//**Configuration and Installation*****************************************************************
/*!\page configuration_and_installation Configuration and Installation
//
// Since \b Blaze is a header-only library, setting up the \b Blaze library on a particular system
// is a fairly easy two step process. In the following, this two step process is explained in
// detail, preceded only by a short summary of the requirements.
//
//
// \n \section requirements Requirements
// <hr>
//
// In order for \b Blaze to work properly, the Boost library must be installed on the system. It
// is recommended to use the newest Boost library available, but \b Blaze requires at minimum the
// Boost version 1.54.0. If you don't have Boost installed on your system, you can download it for
// free from 'http://www.boost.org'.
//
// Additionally, for maximum performance \b Blaze expects you to have a BLAS library installed
// (<a href="http://software.intel.com/en-us/articles/intel-mkl/">Intel MKL</a>,
// <a href="http://developer.amd.com/libraries/acml/">ACML</a>,
// <a href="http://math-atlas.sourceforge.net">Atlas</a>,
// <a href="http://www.tacc.utexas.edu/tacc-projects/gotoblas2">Goto</a>, ...). If you don't
// have a BLAS library installed on your system, \b Blaze will still work and will not be reduced
// in functionality, but performance may be limited. Thus it is strongly recommended to install a
// BLAS library.
//
// Furthermore, for computing the determinant of a dense matrix and for the dense matrix inversion
// \b Blaze requires <a href="https://en.wikipedia.org/wiki/LAPACK">LAPACK</a>. When either of
// these features is used it is necessary to link the LAPACK library to the final executable. If
// no LAPACK library is available the use of these features will result in a linker error.
//
//
// \n \section step_1_installation Step 1: Installation
// <hr>
//
// \subsection step_1_installation_unix Linux/MacOSX User
//
// The first step is the installation of the header files. Since \b Blaze only consists of header
// files, the <tt>./blaze</tt> subdirectory can be simply copied to a standard include directory
// (note that this requires root privileges):
\code
cp -r ./blaze /usr/local/include
\endcode
// Alternatively, on Unix-based machines (which includes Linux and Mac OS X) the
// \c CPLUS_INCLUDE_PATH environment variable can be set. The specified directory will be
// searched after any directories specified on the command line with the option \c -I and
// before the standard default directories (such as \c /usr/local/include and \c /usr/include).
// Assuming a user named 'Jon', the environment variable can be set as follows:
\code
CPLUS_INCLUDE_PATH=/usr/home/jon/blaze
export CPLUS_INCLUDE_PATH
\endcode
// Last but not least, the <tt>./blaze</tt> subdirectory can be explicitly specified on the
// command line. The following example demonstrates this by means of the GNU C++ compiler:
\code
g++ -I/usr/home/jon/blaze -o BlazeTest BlazeTest.cpp
\endcode
// \n \subsection step_1_installation_windows Windows User
//
// Windows doesn't have a standard include directory. Therefore the \b Blaze header files can be
// copied to any other directory or simply left in the default \b Blaze directory. However, the
// chosen include directory has to be explicitly specified as include path. In Visual Studio,
// this is done via the project property pages, configuration properties, C/C++, General settings.
// Here the additional include directories can be specified.
//
//
// \n \section step_2_configuration Step 2: Configuration
// <hr>
//
// The second step is the configuration and customization of the \b Blaze library. Many aspects of
// \b Blaze can be adapted to specific requirements, environments and architectures by customizing
// the header files in the <tt>./blaze/config/</tt> subdirectory. Since the default settings are
// reasonable for most systems this step can also be skipped. However, in order to achieve maximum
// performance a customization of at least the following configuration files is required:
//
// - <b><tt>./blaze/config/BLAS.h</tt></b>: Via this configuration file \b Blaze can be enabled
// to use a third-party BLAS library for several basic linear algebra functions (such as for
// instance dense matrix multiplications). In case no BLAS library is used, all linear algebra
// functions use the default implementations of the \b Blaze library and therefore BLAS is not a
// requirement for the compilation process. However, please note that performance may be limited.
// - <b><tt>./blaze/config/CacheSize.h</tt></b>: This file contains the hardware specific cache
// settings. \b Blaze uses this information to optimize its cache usage. For maximum performance
// it is recommended to adapt these setting to a specific target architecture.
// - <b><tt>./blaze/config/Thresholds.h</tt></b>: This file contains all thresholds for the
// customization of the \b Blaze compute kernels. In order to tune the kernels for a specific
// architecture and to maximize performance it can be necessary to adjust the thresholds,
// especially for a parallel execution (see \ref shared_memory_parallelization).
//
// For an overview of other customization options and more details, please see the section
// \ref configuration_files.
//

//*************************************************************************************************
//**Getting Started********************************************************************************
/*!\page getting_started Getting Started
//
// This short tutorial serves the purpose to give a quick overview of the way mathematical
// expressions have to be formulated in \b Blaze. Starting with \ref vector_types, the following
// long tutorial covers the most important aspects of the \b Blaze math library.
//
//
// \n \section getting_started_vector_example A First Example
//
// \b Blaze is written such that using mathematical expressions is as close to mathematical
// textbooks as possible and therefore as intuitive as possible. In nearly all cases the seemingly
// easiest solution is the right solution and most users experience no problems when trying to
// use \b Blaze in the most natural way. The following example gives a first impression of the
// formulation of a vector addition in \b Blaze:
\code
#include <iostream>
#include <blaze/Math.h>
using blaze::StaticVector;
using blaze::DynamicVector;
// Instantiation of a static 3D column vector. The vector is directly initialized as
// ( 4 -2 5 )
StaticVector<int,3UL> a{ 4, -2, 5 };
// Instantiation of a dynamic 3D column vector. Via the subscript operator the values are set to
// ( 2 5 -3 )
DynamicVector<int> b( 3UL );
b[0] = 2;
b[1] = 5;
b[2] = -3;
// Adding the vectors a and b
DynamicVector<int> c = a + b;
// Printing the result of the vector addition
std::cout << "c =\n" << c << "\n";
\endcode
// Note that the entire \b Blaze math library can be included via the \c blaze/Math.h header
// file. Alternatively, the entire \b Blaze library, including both the math and the entire
// utility module, can be included via the \c blaze/Blaze.h header file. Also note that all
// classes and functions of \b Blaze are contained in the blaze namespace.\n\n
//
// Assuming that this program resides in a source file called \c FirstExample.cpp, it can be
// compiled for instance via the GNU C++ compiler:
\code
g++ -ansi -O3 -DNDEBUG -mavx -o FirstExample FirstExample.cpp
\endcode
// Note the definition of the \c NDEBUG preprocessor symbol. In order to achieve maximum
// performance, it is necessary to compile the program in release mode, which deactivates
// all debugging functionality inside \b Blaze. It is also strongly recommended to specify
// the available architecture specific instruction set (as for instance the AVX instruction
// set, which if available can be activated via the \c -mavx flag). This allows \b Blaze
// to optimize computations via vectorization.\n\n
//
// When running the resulting executable \c FirstExample, the output of the last line of
// this small program is
\code
c =
6
3
2
\endcode
// \n \section getting_started_matrix_example An Example Involving Matrices
//
// Similarly easy and intuitive are expressions involving matrices:
\code
#include <blaze/Math.h>
using namespace blaze;
// Instantiating a dynamic 3D column vector
DynamicVector<int> x{ 4, -1, 3 };
// Instantiating a dynamic 2x3 row-major matrix, preinitialized with 0. Via the function call
// operator three values of the matrix are explicitly set to get the matrix
// ( 1 0 4 )
// ( 0 -2 0 )
DynamicMatrix<int> A( 2UL, 3UL, 0 );
A(0,0) = 1;
A(0,2) = 4;
A(1,1) = -2;
// Performing a matrix/vector multiplication
DynamicVector<int> y = A * x;
// Printing the resulting vector
std::cout << "y =\n" << y << "\n";
// Instantiating a static column-major matrix. The matrix is directly initialized as
// ( 3 -1 )
// ( 0 2 )
// ( -1 0 )
StaticMatrix<int,3UL,2UL,columnMajor> B{ { 3, -1 }, { 0, 2 }, { -1, 0 } };
// Performing a matrix/matrix multiplication
DynamicMatrix<int> C = A * B;
// Printing the resulting matrix
std::cout << "C =\n" << C << "\n";
\endcode
// The output of this program is
\code
y =
16
2
C =
( -1 -1 )
( 0 4 )
\endcode
// \n \section getting_started_complex_example A Complex Example
//
// The following example is much more sophisticated. It shows the implementation of the Conjugate
// Gradient (CG) algorithm (http://en.wikipedia.org/wiki/Conjugate_gradient) by means of the
// \b Blaze library:
//
// \image html cg.jpg
//
// In this example it is not important to understand the CG algorithm itself, but to see the
// advantage of the API of the \b Blaze library. In the \b Blaze implementation we will use a
// sparse matrix/dense vector multiplication for a 2D Poisson equation using \f$ N \times N \f$
// unknowns. It becomes apparent that the core of the algorithm is very close to the mathematical
// formulation and therefore has huge advantages in terms of readability and maintainability,
// while the performance of the code is close to the expected theoretical peak performance:
\code
const size_t NN( N*N );
blaze::CompressedMatrix<double,rowMajor> A( NN, NN );
blaze::DynamicVector<double,columnVector> x( NN, 1.0 ), b( NN, 0.0 ), r( NN ), p( NN ), Ap( NN );
double alpha, beta, delta;
// ... Initializing the sparse matrix A
// Performing the CG algorithm
r = b - A * x;
p = r;
delta = (r,r);
for( size_t iteration=0UL; iteration<iterations; ++iteration )
{
Ap = A * p;
alpha = delta / (p,Ap);
x += alpha * p;
r -= alpha * Ap;
beta = (r,r);
if( std::sqrt( beta ) < 1E-8 ) break;
p = r + ( beta / delta ) * p;
delta = beta;
}
\endcode
// \n Hopefully this short tutorial gives a good first impression of how mathematical expressions
// are formulated with \b Blaze. The following long tutorial, starting with \ref vector_types,
// will cover all aspects of the \b Blaze math library, i.e. it will introduce all vector and
// matrix types, all possible operations on vectors and matrices, and of course all possible
// mathematical expressions.

// <hr>
//
// The blaze::CustomVector class template provides the functionality to represent an external

// structure. Thus in contrast to all other dense vector types a custom vector does not perform
// any kind of memory allocation by itself, but it is provided with an existing array of element
// during construction. A custom vector can therefore be considered an alias to the existing
// array. It can be included via the header file
\code
#include <blaze/math/CustomVector.h>
\endcode
// The type of the elements, the properties of the given array of elements and the transpose
// flag of the vector can be specified via the following four template parameters:
\code
template< typename Type, bool AF, bool PF, bool TF >
class CustomVector;
\endcode
// - Type: specifies the type of the vector elements. blaze::CustomVector can be used with
// any non-cv-qualified, non-reference, non-pointer element type.
// - AF : specifies whether the represented, external arrays are properly aligned with
// respect to the available instruction set (SSE, AVX, ...) or not.
// - PF : specified whether the represented, external arrays are properly padded with
// respect to the available instruction set (SSE, AVX, ...) or not.
// - TF : specifies whether the vector is a row vector (\c blaze::rowVector) or a column
// vector (\c blaze::columnVector). The default value is \c blaze::columnVector.
//
// The blaze::CustomVector is the right choice if any external array needs to be represented as
// a \b Blaze dense vector data structure or if a custom memory allocation strategy needs to be
// realized:
\code
using blaze::CustomVector;
using blaze::aligned;
using blaze::unaligned;
using blaze::padded;
using blaze::unpadded;
// Definition of an unmanaged custom column vector for unaligned, unpadded integer arrays
typedef CustomVector<int,unaligned,unpadded,columnVector> UnalignedUnpadded;
std::vector<int> vec( 7UL );
UnalignedUnpadded a( &vec[0], 7UL );
// Definition of a managed custom column vector for unaligned but padded 'float' arrays
typedef CustomVector<float,unaligned,padded,columnVector> UnalignedPadded;
UnalignedPadded b( new float[16], 9UL, 16UL, blaze::ArrayDelete() );
// Definition of a managed custom row vector for aligned, unpadded 'double' arrays
typedef CustomVector<double,aligned,unpadded,rowVector> AlignedUnpadded;
AlignedUnpadded c( blaze::allocate<double>( 7UL ), 7UL, blaze::Deallocate() );
// Definition of a managed custom row vector for aligned, padded 'complex<double>' arrays
typedef CustomVector<complex<double>,aligned,padded,columnVector> AlignedPadded;
AlignedPadded d( allocate< complex<double> >( 8UL ), 5UL, 8UL, blaze::Deallocate() );
\endcode
// In comparison with the remaining \b Blaze dense vector types blaze::CustomVector has several
// special characteristics. All of these result from the fact that a custom vector is not
// performing any kind of memory allocation, but instead is given an existing array of elements.
// The following sections discuss all of these characteristics:
//
// -# <b>\ref vector_types_custom_vector_memory_management</b>
// -# <b>\ref vector_types_custom_vector_copy_operations</b>
// -# <b>\ref vector_types_custom_vector_alignment</b>
// -# <b>\ref vector_types_custom_vector_padding</b>
//
// \n \subsection vector_types_custom_vector_memory_management Memory Management
//
// The blaze::CustomVector class template acts as an adaptor for an existing array of elements. As
// such it provides everything that is required to use the array just like a native \b Blaze dense
// vector data structure. However, this flexibility comes with the price that the user of a custom
// vector is responsible for the resource management.
//
// When constructing a custom vector there are two choices: Either a user manually manages the
// array of elements outside the custom vector, or alternatively passes the responsibility for
// the memory management to an instance of CustomVector. In the second case the CustomVector
// class employs shared ownership between all copies of the custom vector, which reference the
// same array.
//
// The following examples give an impression of several possible types of custom vectors:
\code
using blaze::CustomVector;
using blaze::ArrayDelete;
using blaze::Deallocate;
using blaze::allocate;
using blaze::aligned;
using blaze::unaligned;
using blaze::padded;
using blaze::unpadded;
using blaze::columnVector;
using blaze::rowVector;
// Definition of a 3-dimensional custom vector with unaligned, unpadded and externally
// managed integer array. Note that the std::vector must be guaranteed to outlive the
// custom vector!
std::vector<int> vec( 3UL );
CustomVector<int,unaligned,unpadded> a( &vec[0], 3UL );
// Definition of a custom row vector with size 3 for unaligned, unpadded integer arrays.
// The responsibility for the memory management is passed to the custom vector by
// providing a deleter of type 'blaze::ArrayDelete' that is used during the destruction
// of the custom vector.
CustomVector<int,unaligned,unpadded,rowVector> b( new int[3], 3UL, ArrayDelete() );
// Definition of a custom vector with size 3 and capacity 16 with aligned and padded
// integer array. The memory management is passed to the custom vector by providing a
// deleter of type 'blaze::Deallocate'.
CustomVector<int,aligned,padded> c( allocate<int>( 16UL ), 3UL, 16UL, Deallocate() );
\endcode
// It is possible to pass any type of deleter to the constructor. The deleter is only required
// to provide a function call operator that can be passed the pointer to the managed array. As
// an example the following code snipped shows the implementation of two native \b Blaze deleters
// blaze::ArrayDelete and blaze::Deallocate:
\code
namespace blaze {
struct ArrayDelete
{
template< typename Type >
inline void operator()( Type ptr ) const { boost::checked_array_delete( ptr ); }
};
struct Deallocate
{
template< typename Type >
inline void operator()( Type ptr ) const { deallocate( ptr ); }
};
} // namespace blaze
\endcode
// \n \subsection vector_types_custom_vector_copy_operations Copy Operations
//
// As with all dense vectors it is possible to copy construct a custom vector:
\code
using blaze::CustomVector;
using blaze::unaligned;
using blaze::unpadded;
typedef CustomVector<int,unaligned,unpadded> CustomType;
std::vector<int> vec( 5UL, 10 ); // Vector of 5 integers of the value 10
CustomType a( &vec[0], 5UL ); // Represent the std::vector as Blaze dense vector
a[1] = 20; // Also modifies the std::vector
CustomType b( a ); // Creating a copy of vector a
b[2] = 20; // Also affect vector a and the std::vector
\endcode
// It is important to note that a custom vector acts as a reference to the specified array. Thus
// the result of the copy constructor is a new custom vector that is referencing and representing
// the same array as the original custom vector. In case a deleter has been provided to the first
// custom vector, both vectors share the responsibility to destroy the array when the last vector
// goes out of scope.
//
// In contrast to copy construction, just as with references, copy assignment does not change
// which array is referenced by the custom vector, but modifies the values of the array:
\code
std::vector<int> vec2( 5UL, 4 ); // Vector of 5 integers of the value 4
CustomType c( &vec2[0], 5UL ); // Represent the std::vector as Blaze dense vector
a = c; // Copy assignment: Set all values of vector a and b to 4.
\endcode
// \n \subsection vector_types_custom_vector_alignment Alignment
//
// In case the custom vector is specified as \c aligned the passed array must be guaranteed to
// be aligned according to the requirements of the used instruction set (SSE, AVX, ...). For
// instance, if AVX is active an array of integers must be 32-bit aligned:
\code
using blaze::CustomVector;
using blaze::Deallocate;
using blaze::aligned;
using blaze::unpadded;
int* array = blaze::allocate<int>( 5UL ); // Needs to be 32-bit aligned
CustomVector<int,aligned,unpadded> a( array, 5UL, Deallocate() );
\endcode
// In case the alignment requirements are violated, a \c std::invalid_argument exception is
// thrown.
//
// \n \subsection vector_types_custom_vector_padding Padding
//
// Adding padding elements to the end of an array can have a significant impact on the performance.
// For instance, assuming that AVX is available, then two aligned, padded, 3-dimensional vectors
// of double precision values can be added via a single SIMD addition operation:
\code
using blaze::CustomVector;
using blaze::Deallocate;
using blaze::allocate;
using blaze::aligned;
using blaze::padded;
typedef CustomVector<double,aligned,padded> CustomType;
// Creating padded custom vectors of size 3 and a capacity of 4
CustomType a( allocate<double>( 4UL ), 3UL, 4UL, Deallocate() );
CustomType b( allocate<double>( 4UL ), 3UL, 4UL, Deallocate() );
CustomType c( allocate<double>( 4UL ), 3UL, 4UL, Deallocate() );
// ... Initialization
c = a + b; // AVX-based vector addition
\endcode
// In this example, maximum performance is possible. However, in case no padding elements are
// inserted, a scalar addition has to be used:
\code
using blaze::CustomVector;
using blaze::Deallocate;
using blaze::allocate;
using blaze::aligned;
using blaze::unpadded;
typedef CustomVector<double,aligned,unpadded> CustomType;
// Creating unpadded custom vector of size 3
CustomType a( allocate<double>( 3UL ), 3UL, Deallocate() );
CustomType b( allocate<double>( 3UL ), 3UL, Deallocate() );
CustomType c( allocate<double>( 3UL ), 3UL, Deallocate() );
// ... Initialization
c = a + b; // Scalar vector addition
\endcode
// Note the different number of constructor parameters for unpadded and padded custom vectors:
// In contrast to unpadded vectors, where during the construction only the size of the array
// has to be specified, during the construction of a padded custom vector it is additionally
// necessary to explicitly specify the capacity of the array.
//
// The number of padding elements is required to be sufficient with respect to the available
// instruction set: In case of an aligned padded custom vector the added padding elements must
// guarantee that the capacity is a multiple of the SIMD vector width. In case of unaligned
// padded vectors \f$ N-1 \f$ additional padding elements are required, where \f$ N \f$ is
// the SIMD vector width. In case the padding is insufficient with respect to the available
// instruction set, a \c std::invalid_argument exception is thrown.
//
// Please also note that \b Blaze will zero initialize the padding elements in order to achieve
// maximum performance!
//
//
// \n \section vector_types_compressed_vector CompressedVector
// <hr>
//
// The blaze::CompressedVector class is the representation of an arbitrarily sized sparse
// vector, which stores only non-zero elements of arbitrary type. It can be included via the
// header file
\code
#include <blaze/math/CompressedVector.h>
\endcode
// The type of the elements and the transpose flag of the vector can be specified via the two
// template parameters:
\code
template< typename Type, bool TF >
class CompressedVector;
\endcode
// - \c Type: specifies the type of the vector elements. CompressedVector can be used with any
// non-cv-qualified, non-reference, non-pointer element type.
// - \c TF : specifies whether the vector is a row vector (\c blaze::rowVector) or a column
// vector (\c blaze::columnVector). The default value is \c blaze::columnVector.
//
// The blaze::CompressedVector is the right choice for all kinds of sparse vectors:
\code
// Definition of a 3-dimensional integral column vector
blaze::CompressedVector<int> a( 3UL );
// Definition of a 4-dimensional single precision column vector with capacity for 3 non-zero elements
blaze::CompressedVector<float,blaze::columnVector> b( 4UL, 3UL );

// \n \section vector_operations_constructors Constructors
// <hr>
//
// Instantiating and setting up a vector is very easy and intuitive. However, there are a few
// rules to take care of:
// - In case the last template parameter (the transpose flag) is omitted, the vector is per
// default a column vector.
// - The elements of a \c StaticVector or \c HybridVector are default initialized (i.e. built-in
// data types are initialized to 0, class types are initialized via the default constructor).
// - Newly allocated elements of a \c DynamicVector or \c CompressedVector remain uninitialized
// if they are of built-in type and are default constructed if they are of class type.
//
// \n \subsection vector_operations_default_construction Default Construction
\code
using blaze::StaticVector;
using blaze::DynamicVector;
using blaze::CompressedVector;
// All vectors can be default constructed. Whereas the size
// of StaticVectors is fixed via the second template parameter,
// the initial size of a default constructed DynamicVector or
// CompressedVector is 0.
StaticVector<int,2UL> v1; // Instantiation of a 2D integer column vector.
// All elements are initialized to 0.
StaticVector<long,3UL,columnVector> v2; // Instantiation of a 3D long integer column vector.
// Again, all elements are initialized to 0L.
DynamicVector<float> v3; // Instantiation of a dynamic single precision column
// vector of size 0.
DynamicVector<double,rowVector> v4; // Instantiation of a dynamic double precision row
// vector of size 0.
CompressedVector<int> v5; // Instantiation of a compressed integer column
// vector of size 0.
CompressedVector<double,rowVector> v6; // Instantiation of a compressed double precision row
// vector of size 0.
\endcode
// \n \subsection vector_operations_size_construction Construction with Specific Size
//
// The \c DynamicVector, \c HybridVector and \c CompressedVector classes offer a constructor that
// allows to immediately give the vector the required size. Whereas both dense vectors (i.e.
// \c DynamicVector and \c HybridVector) use this information to allocate memory for all vector
// elements, \c CompressedVector merely acquires the size but remains empty.
\code
DynamicVector<int,columnVector> v7( 9UL ); // Instantiation of an integer dynamic column vector
// of size 9. The elements are NOT initialized!
HybridVector< complex<float>, 5UL > v8( 2UL ); // Instantiation of a column vector with two single
// precision complex values. The elements are
// default constructed.
CompressedVector<int,rowVector> v9( 10UL ); // Instantiation of a compressed row vector with
// size 10. Initially, the vector provides no
// capacity for non-zero elements.
\endcode
// \n \subsection vector_operations_initialization_constructors Initialization Constructors
//
// All dense vector classes offer a constructor that allows for a direct, homogeneous initialization
// of all vector elements. In contrast, for sparse vectors the predicted number of non-zero elements
// can be specified
\code
StaticVector<int,3UL,rowVector> v10( 2 ); // Instantiation of a 3D integer row vector.
// All elements are initialized to 2.
DynamicVector<float> v11( 3UL, 7.0F ); // Instantiation of a dynamic single precision
// column vector of size 3. All elements are
// set to 7.0F.
CompressedVector<float,rowVector> v12( 15UL, 3UL ); // Instantiation of a single precision column
// vector of size 15, which provides enough
// space for at least 3 non-zero elements.
\endcode
// \n \subsection vector_operations_array_construction Array Construction
//
// Alternatively, all dense vector classes offer a constructor for an initialization with a dynamic
// or static array. If the vector is initialized from a dynamic array, the constructor expects the
// actual size of the array as first argument, the array as second argument. In case of a static
// array, the fixed size of the array is used:
\code
const unique_ptr<double[]> array1( new double[2] );
// ... Initialization of the dynamic array
blaze::StaticVector<double,2UL> v13( 2UL, array1.get() );
int array2[4] = { 4, -5, -6, 7 };
blaze::StaticVector<int,4UL> v14( array2 );
\endcode
// \n \subsection vector_operations_initializer_list_construction Initializer List Construction
//
// In addition, all dense vector classes can be directly initialized by means of an initializer
// list:
\code
blaze::DynamicVector<float> v15{ 1.0F, 2.0F, 3.0F, 4.0F };
\endcode
// \n \subsection vector_operations_copy_construction Copy Construction
//
// All dense and sparse vectors can be created as the copy of any other dense or sparse vector
// with the same transpose flag (i.e. blaze::rowVector or blaze::columnVector).
\code
StaticVector<int,9UL,columnVector> v16( v7 ); // Instantiation of the dense column vector v16
// as copy of the dense column vector v7.
DynamicVector<int,rowVector> v17( v9 ); // Instantiation of the dense row vector v17 as
// copy of the sparse row vector v9.
CompressedVector<int,columnVector> v18( v1 ); // Instantiation of the sparse column vector v18
// as copy of the dense column vector v1.
CompressedVector<float,rowVector> v19( v12 ); // Instantiation of the sparse row vector v19 as
// copy of the row vector v12.
\endcode
// Note that it is not possible to create a \c StaticVector as a copy of a vector with a different
// size:
\code
StaticVector<int,5UL,columnVector> v23( v7 ); // Runtime error: Size does not match!
StaticVector<int,4UL,rowVector> v24( v10 ); // Compile time error: Size does not match!
\endcode
// \n \section vector_operations_assignment Assignment
// <hr>
//
// There are several types of assignment to dense and sparse vectors:
// \ref vector_operations_homogeneous_assignment, \ref vector_operations_array_assignment,
// \ref vector_operations_copy_assignment, and \ref vector_operations_compound_assignment.
//
// \n \subsection vector_operations_homogeneous_assignment Homogeneous Assignment
//
// Sometimes it may be necessary to assign the same value to all elements of a dense vector.
// For this purpose, the assignment operator can be used:
\code
blaze::StaticVector<int,3UL> v1;
blaze::DynamicVector<double> v2;
// Setting all integer elements of the StaticVector to 2
v1 = 2;
// Setting all double precision elements of the DynamicVector to 5.0
v2 = 5.0;
\endcode
// \n \subsection vector_operations_array_assignment Array Assignment
//
// Dense vectors can also be assigned a static array:
\code
blaze::StaticVector<float,2UL> v1;
blaze::DynamicVector<double,rowVector> v2;
float array1[2] = { 1.0F, 2.0F };
double array2[5] = { 2.1, 4.0, -1.7, 8.6, -7.2 };
v1 = array1;
v2 = array2;
\endcode
// \n \subsection vector_operations_initializer_list_assignment Initializer List Assignment
//
// Alternatively, it is possible to directly assign an initializer list to a dense vector:
\code
blaze::StaticVector<float,2UL> v1;
blaze::DynamicVector<double,rowVector> v2;
v1 = { 1.0F, 2.0F };
v2 = { 2.1, 4.0, -1.7, 8.6, -7.2 };
\endcode
// \n \subsection vector_operations_copy_assignment Copy Assignment
//
// For all vector types it is generally possible to assign another vector with the same transpose
// flag (i.e. blaze::columnVector or blaze::rowVector). Note that in case of \c StaticVectors, the
// assigned vector is required to have the same size as the \c StaticVector since the size of a
// \c StaticVector cannot be adapted!
\code
blaze::StaticVector<int,3UL,columnVector> v1;
blaze::DynamicVector<int,columnVector> v2( 3UL );
blaze::DynamicVector<float,columnVector> v3( 5UL );
blaze::CompressedVector<int,columnVector> v4( 3UL );
blaze::CompressedVector<float,rowVector> v5( 3UL );
// ... Initialization of the vectors
v1 = v2; // OK: Assignment of a 3D dense column vector to another 3D dense column vector
v1 = v4; // OK: Assignment of a 3D sparse column vector to a 3D dense column vector
v1 = v3; // Runtime error: Cannot assign a 5D vector to a 3D static vector
v1 = v5; // Compilation error: Cannot assign a row vector to a column vector
\endcode
// \n \subsection vector_operations_compound_assignment Compound Assignment
//
// Next to plain assignment, it is also possible to use addition assignment, subtraction
// assignment, and multiplication assignment. Note however, that in contrast to plain assignment
// the size and the transpose flag of the vectors has be to equal in order to able to perform a
// compound assignment.
\code
blaze::StaticVector<int,5UL,columnVector> v1;
blaze::DynamicVector<int,columnVector> v2( 5UL );
blaze::CompressedVector<float,columnVector> v3( 7UL );
blaze::DynamicVector<float,rowVector> v4( 7UL );
blaze::CompressedVector<float,rowVector> v5( 7UL );
// ... Initialization of the vectors
v1 += v2; // OK: Addition assignment between two column vectors of the same size
v1 += v3; // Runtime error: No compound assignment between vectors of different size
v1 -= v4; // Compilation error: No compound assignment between vectors of different transpose flag
v4 *= v5; // OK: Multiplication assignment between two row vectors of the same size
\endcode
// \n \section vector_operations_element_access Element Access
// <hr>
//
// The easiest and most intuitive way to access a dense or sparse vector is via the subscript
// operator. The indices to access a vector are zero-based:
\code
blaze::DynamicVector<int> v1( 5UL );
v1[0] = 1;
v1[1] = 3;
// ...
blaze::CompressedVector<float> v2( 5UL );
v2[2] = 7.3F;
v2[4] = -1.4F;
\endcode
// Whereas using the subscript operator on a dense vector only accesses the already existing
// element, accessing an element of a sparse vector via the subscript operator potentially
// inserts the element into the vector and may therefore be more expensive. Consider the
// following example:
\code
blaze::CompressedVector<int> v1( 10UL );
for( size_t i=0UL; i<v1.size(); ++i ) {
... = v1[i];
}
\endcode
// Although the compressed vector is only used for read access within the for loop, using the
// subscript operator temporarily inserts 10 non-zero elements into the vector. Therefore, all
// vectors (sparse as well as dense) offer an alternate way via the \c begin(), \c cbegin(),
// \c end(), and \c cend() functions to traverse the currently contained elements by iterators.
// In case of non-const vectors, \c begin() and \c end() return an \c Iterator, which allows a
// manipulation of the non-zero value, in case of a constant vector or in case \c cbegin() or
// \c cend() are used a \c ConstIterator is returned:
\code
using blaze::CompressedVector;
CompressedVector<int> v1( 10UL );
// ... Initialization of the vector
// Traversing the vector by Iterator
for( CompressedVector<int>::Iterator it=v1.begin(); it!=v1.end(); ++it ) {
it->value() = ...; // OK: Write access to the value of the non-zero element.
... = it->value(); // OK: Read access to the value of the non-zero element.
it->index() = ...; // Compilation error: The index of a non-zero element cannot be changed.
... = it->index(); // OK: Read access to the index of the non-zero element.
}
// Traversing the vector by ConstIterator
for( CompressedVector<int>::ConstIterator it=v1.cbegin(); it!=v1.cend(); ++it ) {
it->value() = ...; // Compilation error: Assignment to the value via a ConstIterator is invalid.
... = it->value(); // OK: Read access to the value of the non-zero element.
it->index() = ...; // Compilation error: The index of a non-zero element cannot be changed.
... = it->index(); // OK: Read access to the index of the non-zero element.
}
\endcode
// Note that \c begin(), \c cbegin(), \c end(), and \c cend() are also available as free functions:
\code
for( CompressedVector<int>::Iterator it=begin( v1 ); it!=end( v1 ); ++it ) {
// ...
}
for( CompressedVector<int>::ConstIterator it=cbegin( v1 ); it!=cend( v1 ); ++it ) {
// ...
}
\endcode
// \n \section vector_operations_element_insertion Element Insertion
// <hr>
//
// In contrast to dense vectors, that store all elements independent of their value and that
// offer direct access to all elements, spares vectors only store the non-zero elements contained
// in the vector. Therefore it is necessary to explicitly add elements to the vector. The first
// option to add elements to a sparse vector is the subscript operator:
\code
using blaze::CompressedVector;
CompressedVector<int> v1( 3UL );
v1[1] = 2;
\endcode
// In case the element at the given index is not yet contained in the vector, it is automatically
// inserted. Otherwise the old value is replaced by the new value 2. The operator returns a
// reference to the sparse vector element.\n
// An alternative is the \c set() function: In case the element is not yet contained in the vector
// the element is inserted, else the element's value is modified:
\code
// Insert or modify the value at index 3
v1.set( 3, 1 );
\endcode
// However, insertion of elements can be better controlled via the \c insert() function. In contrast
// to the subscript operator and the \c set() function it emits an exception in case the element is
// already contained in the vector. In order to check for this case, the \c find() function can be
// used:
\code
// In case the element at index 4 is not yet contained in the matrix it is inserted
// with a value of 6.
if( v1.find( 4 ) == v1.end() )
v1.insert( 4, 6 );
\endcode
// Although the \c insert() function is very flexible, due to performance reasons it is not suited
// for the setup of large sparse vectors. A very efficient, yet also very low-level way to fill
// a sparse vector is the \c append() function. It requires the sparse vector to provide enough
// capacity to insert a new element. Additionally, the index of the new element must be larger
// than the index of the previous element. Violating these conditions results in undefined
// behavior!
\code
v1.reserve( 10 ); // Reserving space for 10 non-zero elements
v1.append( 5, -2 ); // Appending the element -2 at index 5
v1.append( 6, 4 ); // Appending the element 4 at index 6
// ...
\endcode
// \n \section vector_operations_member_functions Member Functions
// <hr>
//
// \subsection vector_operations_size .size()
//
// Via the \c size() member function, the current size of a dense or sparse vector can be queried:
\code
// Instantiating a dynamic vector with size 10
blaze::DynamicVector<int> v1( 10UL );
v1.size(); // Returns 10
// Instantiating a compressed vector with size 12 and capacity for 3 non-zero elements
blaze::CompressedVector<double> v2( 12UL, 3UL );
v2.size(); // Returns 12
\endcode
// Alternatively, the free function \c size() can be used to query to current size of a vector.
// In contrast to the member function, the free function can also be used to query the size of
// vector expressions:
\code
size( v1 ); // Returns 10, i.e. has the same effect as the member function
size( v2 ); // Returns 12, i.e. has the same effect as the member function
blaze::DynamicMatrix<int> A( 15UL, 12UL );
size( A * v2 ); // Returns 15, i.e. the size of the resulting vector
\endcode
// \n \subsection vector_operations_capacity .capacity()
//
// Via the \c capacity() (member) function the internal capacity of a dense or sparse vector
// can be queried. Note that the capacity of a vector doesn't have to be equal to the size
// of a vector. In case of a dense vector the capacity will always be greater or equal than
// the size of the vector, in case of a sparse vector the capacity may even be less than
// the size.
\code
v1.capacity(); // Returns at least 10
\endcode
// For symmetry reasons, there is also a free function /c capacity() available that can be used
// to query the capacity:
\code
capacity( v1 ); // Returns at least 10, i.e. has the same effect as the member function
\endcode
// Note, however, that it is not possible to query the capacity of a vector expression:
\code
capacity( A * v1 ); // Compilation error!
\endcode
// \n \subsection vector_operations_nonzeros .nonZeros()
//
// For both dense and sparse vectors the number of non-zero elements can be determined via the
// \c nonZeros() member function. Sparse vectors directly return their number of non-zero
// elements, dense vectors traverse their elements and count the number of non-zero elements.
\code
v1.nonZeros(); // Returns the number of non-zero elements in the dense vector
v2.nonZeros(); // Returns the number of non-zero elements in the sparse vector
\endcode
// There is also a free function \c nonZeros() available to query the current number of non-zero
// elements:
\code
nonZeros( v1 ); // Returns the number of non-zero elements in the dense vector
nonZeros( v2 ); // Returns the number of non-zero elements in the sparse vector
\endcode
// The free \c nonZeros() function can also be used to query the number of non-zero elements in
// a vector expression. However, the result is not the exact number of non-zero elements, but
// may be a rough estimation:
\code
nonZeros( A * v1 ); // Estimates the number of non-zero elements in the vector expression
\endcode
// \n \subsection vector_operations_resize_reserve .resize() / .reserve()
//
// The size of a \c StaticVector is fixed by the second template parameter and a \c CustomVector
// cannot be resized. In contrast, the size of \c DynamicVectors, \c HybridVectors as well as
// \c CompressedVectors can be changed via the \c resize() function:
\code
using blaze::DynamicVector;
using blaze::CompressedVector;
DynamicVector<int,columnVector> v1;
CompressedVector<int,rowVector> v2( 4 );
v2[1] = -2;
v2[3] = 11;
// Adapting the size of the dynamic and compressed vectors. The (optional) second parameter
// specifies whether the existing elements should be preserved. Per default, the existing
// elements are not preserved.
v1.resize( 5UL ); // Resizing vector v1 to 5 elements. Elements of built-in type remain
// uninitialized, elements of class type are default constructed.
v1.resize( 3UL, false ); // Resizing vector v1 to 3 elements. The old elements are lost, the
// new elements are NOT initialized!
v2.resize( 8UL, true ); // Resizing vector v2 to 8 elements. The old elements are preserved.
v2.resize( 5UL, false ); // Resizing vector v2 to 5 elements. The old elements are lost.
\endcode
// Note that resizing a vector invalidates all existing views (see e.g. \ref views_subvectors)
// on the vector:
\code
typedef blaze::DynamicVector<int,rowVector> VectorType;
typedef blaze::Subvector<VectorType> SubvectorType;
VectorType v1( 10UL ); // Creating a dynamic vector of size 10
SubvectorType sv = subvector( v1, 2UL, 5UL ); // Creating a view on the range [2..6]
v1.resize( 6UL ); // Resizing the vector invalidates the view
\endcode
// When the internal capacity of a vector is no longer sufficient, the allocation of a larger
// junk of memory is triggered. In order to avoid frequent reallocations, the \c reserve()
// function can be used up front to set the internal capacity:
\code
blaze::DynamicVector<int> v1;
v1.reserve( 100 );
v1.size(); // Returns 0
v1.capacity(); // Returns at least 100
\endcode
// Note that the size of the vector remains unchanged, but only the internal capacity is set
// according to the specified value!
//
//
// \n \section vector_operations_free_functions Free Functions

// \subsection vector_operations_reset_clear reset() / clear()
//
// In order to reset all elements of a vector, the \c reset() function can be used:

// Setup of a single precision column vector, whose elements are initialized with 2.0F.
blaze::DynamicVector<float> v1( 3UL, 2.0F );
// Resetting all elements to 0.0F. Only the elements are reset, the size of the vector is unchanged.

// Setup of a single precision column vector, whose elements are initialized with -1.0F.
blaze::DynamicVector<float> v1( 5, -1.0F );
// Resetting the entire vector.
clear( v1 ); // Resetting the entire vector

\code

//
//
// \n \subsection vector_operations_isdefault isDefault()
//
// The \c isDefault() function returns whether the given dense or sparse vector is in default state:
\code
blaze::HybridVector<int,20UL> a;

// A vector is in default state if it appears to just have been default constructed. All resizable

// subvectors, rows, and columns) is in default state if all its elements are in default state.
// For instance, in case the vector is instantiated for a built-in integral or floating point data
// type, the function returns \c true in case all vector elements are 0 and \c false in case any

// \n \subsection vector_operations_isUniform isUniform()
//
// In order to check if all vector elements are identical, the \c isUniform function can be used:

// Note that in case of sparse vectors also the zero elements are also taken into account!
//
//
// \n \subsection vector_operations_min_max min() / max()
//
// The \c min() and the \c max() functions return the smallest and largest element of the given
// dense or sparse vector, respectively:
\code
blaze::StaticVector<int,4UL,rowVector> a{ -5, 2, 7, 4 };
blaze::StaticVector<int,4UL,rowVector> b{ -5, 2, -7, -4 };
min( a ); // Returns -5
min( b ); // Returns -7
max( a ); // Returns 7
max( b ); // Returns 2
\endcode
// In case the vector currently has a size of 0, both functions return 0. Additionally, in case
// a given sparse vector is not completely filled, the zero elements are taken into account. For
// example: the following compressed vector has only 2 non-zero elements. However, the minimum
// of this vector is 0:
\code
blaze::CompressedVector<int> c( 4UL, 2UL );
c[0] = 1;
c[2] = 3;
min( c ); // Returns 0
\endcode
// Also note that the \c min() and \c max() functions can be used to compute the smallest and
// largest element of a vector expression:
\code
min( a + b + c ); // Returns -9, i.e. the smallest value of the resulting vector
max( a - b - c ); // Returns 11, i.e. the largest value of the resulting vector
\endcode
// \n \subsection vector_operators_abs abs()
//
// The \c abs() function can be used to compute the absolute values of each element of a vector.

//
// The \c clip() function can be used to restrict all elements of a vector to a specific range:

blaze::StaticVector<double,3UL> a, b;
b = log( a ); // Computes the natural logarithm of each element
b = log2( a ); // Computes the binary logarithm of each element
b = log10( a ); // Computes the common logarithm of each element
\endcode
// \n \subsection vector_operations_trigonometric_functions sin() / cos() / tan() / asin() / acos() / atan()

//
//
// \n \subsection vector_operations_erf erf() / erfc()

//
//
// \n \subsection vector_operations_foreach forEach()
//

b = forEach( a, []( double d ) { return std::sqrt( d ); } );
\endcode
// Although the computation can be parallelized it is not vectorized and thus cannot perform at
// peak performance. However, it is also possible to create vectorized custom operations. See
// \ref custom_operations for a detailed overview of the possibilities of custom operations.
//
//
// \n \subsection vector_operations_length length() / sqrLength()
//
// In order to calculate the length of a vector, both the \c length() and \c sqrLength() function
// can be used:
\code
blaze::StaticVector<float,3UL,rowVector> v{ -1.2F, 2.7F, -2.3F };
const float len = length ( v ); // Computes the current length of the vector
const float sqrlen = sqrLength( v ); // Computes the square length of the vector
\endcode
// Note that both functions can only be used for vectors with built-in or complex element type!
//
//
// \n \subsection vector_operations_vector_transpose trans()
//
// As already mentioned, vectors can either be column vectors (blaze::columnVector) or row vectors
// (blaze::rowVector). A column vector cannot be assigned to a row vector and vice versa. However,
// vectors can be transposed via the \c trans() function:
\code
blaze::DynamicVector<int,columnVector> v1( 4UL );
blaze::CompressedVector<int,rowVector> v2( 4UL );
v1 = v2; // Compilation error: Cannot assign a row vector to a column vector
v1 = trans( v2 ); // OK: Transposing the row vector to a column vector and assigning it
// to the column vector v1
v2 = trans( v1 ); // OK: Transposing the column vector v1 and assigning it to the row vector v2
v1 += trans( v2 ); // OK: Addition assignment of two column vectors
\endcode
// \n \subsection vector_operations_conjugate_transpose ctrans()
//
// It is also possible to compute the conjugate transpose of a vector. This operation is available
// via the \c ctrans() function:
\code
blaze::CompressedVector< complex<float>, rowVector > v1( 4UL );
blaze::DynamicVector< complex<float>, columnVector > v2( 4UL );
v1 = ctrans( v2 ); // Compute the conjugate transpose vector
\endcode
// Note that the \c ctrans() function has the same effect as manually applying the \c conj() and
// \c trans() function in any order:
\code
v1 = trans( conj( v2 ) ); // Computing the conjugate transpose vector
v1 = conj( trans( v2 ) ); // Computing the conjugate transpose vector
\endcode
// \n \subsection vector_operations_normalize normalize()
//
// The \c normalize() function can be used to scale any non-zero vector to a length of 1. In
// case the vector does not contain a single non-zero element (i.e. is a zero vector), the
// \c normalize() function returns a zero vector.
\code
blaze::DynamicVector<float,columnVector> v1( 10UL );
blaze::CompressedVector<double,columnVector> v2( 12UL );
v1 = normalize( v1 ); // Normalizing the dense vector v1
length( v1 ); // Returns 1 (or 0 in case of a zero vector)
v1 = normalize( v2 ); // Assigning v1 the normalized vector v2
length( v1 ); // Returns 1 (or 0 in case of a zero vector)
\endcode
// Note that the \c normalize() function only works for floating point vectors. The attempt to
// use it for an integral vector results in a compile time error.
//
// \n \subsection vector_operations_swap swap()
//
// Via the \c swap() function it is possible to completely swap the contents of two vectors of
// the same type:
\code
blaze::DynamicVector<int,columnVector> v1( 10UL );
blaze::DynamicVector<int,columnVector> v2( 20UL );
swap( v1, v2 ); // Swapping the contents of v1 and v2

// <hr>
//
// The blaze::CustomMatrix class template provides the functionality to represent an external
// array of elements of arbitrary type and a fixed size as a native \b Blaze dense matrix data
// structure. Thus in contrast to all other dense matrix types a custom matrix does not perform
// any kind of memory allocation by itself, but it is provided with an existing array of element
// during construction. A custom matrix can therefore be considered an alias to the existing
// array. It can be included via the header file
\code
#include <blaze/math/CustomMatrix.h>
\endcode
// The type of the elements, the properties of the given array of elements and the storage order
// of the matrix can be specified via the following four template parameters:
\code
template< typename Type, bool AF, bool PF, bool SO >
class CustomMatrix;
\endcode
// - Type: specifies the type of the matrix elements. blaze::CustomMatrix can be used with
// any non-cv-qualified, non-reference, non-pointer element type.
// - AF : specifies whether the represented, external arrays are properly aligned with
// respect to the available instruction set (SSE, AVX, ...) or not.
// - PF : specified whether the represented, external arrays are properly padded with
// respect to the available instruction set (SSE, AVX, ...) or not.
// - SO : specifies the storage order (blaze::rowMajor, blaze::columnMajor) of the matrix.
// The default value is blaze::rowMajor.
//
// The blaze::CustomMatrix is the right choice if any external array needs to be represented as
// a \b Blaze dense matrix data structure or if a custom memory allocation strategy needs to be
// realized:
\code
using blaze::CustomMatrix;
using blaze::aligned;
using blaze::unaligned;
using blaze::padded;
using blaze::unpadded;
// Definition of an unmanaged 3x4 custom matrix for unaligned, unpadded integer arrays

// In comparison with the remaining \b Blaze dense matrix types blaze::CustomMatrix has several
// special characteristics. All of these result from the fact that a custom matrix is not
// performing any kind of memory allocation, but instead is given an existing array of elements.
// The following sections discuss all of these characteristics:
//
// -# <b>\ref matrix_types_custom_matrix_memory_management</b>
// -# <b>\ref matrix_types_custom_matrix_copy_operations</b>
// -# <b>\ref matrix_types_custom_matrix_alignment</b>
// -# <b>\ref matrix_types_custom_matrix_padding</b>
//
// \n \subsection matrix_types_custom_matrix_memory_management Memory Management
//
// The blaze::CustomMatrix class template acts as an adaptor for an existing array of elements. As
// such it provides everything that is required to use the array just like a native \b Blaze dense
// matrix data structure. However, this flexibility comes with the price that the user of a custom
// matrix is responsible for the resource management.
//
// When constructing a custom matrix there are two choices: Either a user manually manages the
// array of elements outside the custom matrix, or alternatively passes the responsibility for
// the memory management to an instance of CustomMatrix. In the second case the CustomMatrix
// class employs shared ownership between all copies of the custom matrix, which reference the
// same array.
//
// The following examples give an impression of several possible types of custom matrices:
\code
using blaze::CustomMatrix;
using blaze::ArrayDelete;
using blaze::Deallocate;
using blaze::allocate;
using blaze::aligned;
using blaze::unaligned;
using blaze::padded;
using blaze::unpadded;
using blaze::rowMajor;
using blaze::columnMajor;
// Definition of a 3x4 custom row-major matrix with unaligned, unpadded and externally
// managed integer array. Note that the std::vector must be guaranteed to outlive the
// custom matrix!
std::vector<int> vec( 12UL );
CustomMatrix<int,unaligned,unpadded> A( &vec[0], 3UL, 4UL );
// Definition of a 3x4 custom row-major matrix for unaligned, unpadded integer arrays.
// The responsibility for the memory management is passed to the custom matrix by
// providing a deleter of type 'blaze::ArrayDelete' that is used during the destruction
// of the custom matrix.
CustomMatrix<int,unaligned,unpadded,rowMajor> B( new int[12], 3UL, 4UL, ArrayDelete() );
// Definition of a custom 8x12 matrix for an aligned and padded integer array of
// capacity 128 (including 8 padding elements per row). The memory management is passed
// to the custom matrix by providing a deleter of type 'blaze::Deallocate'.
CustomMatrix<int,aligned,padded> C( allocate<int>( 128UL ), 8UL, 12UL, 16UL, Deallocate() );
\endcode
// It is possible to pass any type of deleter to the constructor. The deleter is only required
// to provide a function call operator that can be passed the pointer to the managed array. As
// an example the following code snipped shows the implementation of two native \b Blaze deleters
// blaze::ArrayDelete and blaze::Deallocate:
\code
namespace blaze {
struct ArrayDelete
{
template< typename Type >
inline void operator()( Type ptr ) const { boost::checked_array_delete( ptr ); }
};
struct Deallocate
{
template< typename Type >
inline void operator()( Type ptr ) const { deallocate( ptr ); }
};
} // namespace blaze
\endcode
// \n \subsection matrix_types_custom_matrix_copy_operations Copy Operations
//
// As with all dense matrices it is possible to copy construct a custom matrix:
\code
using blaze::CustomMatrix;
using blaze::unaligned;
using blaze::unpadded;
typedef CustomMatrix<int,unaligned,unpadded> CustomType;
std::vector<int> vec( 6UL, 10 ); // Vector of 6 integers of the value 10
CustomType A( &vec[0], 2UL, 3UL ); // Represent the std::vector as Blaze dense matrix
a[1] = 20; // Also modifies the std::vector
CustomType B( a ); // Creating a copy of vector a
b[2] = 20; // Also affect matrix A and the std::vector
\endcode
// It is important to note that a custom matrix acts as a reference to the specified array. Thus
// the result of the copy constructor is a new custom matrix that is referencing and representing
// the same array as the original custom matrix. In case a deleter has been provided to the first
// custom matrix, both matrices share the responsibility to destroy the array when the last matrix
// goes out of scope.
//
// In contrast to copy construction, just as with references, copy assignment does not change
// which array is referenced by the custom matrices, but modifies the values of the array:
\code
std::vector<int> vec2( 6UL, 4 ); // Vector of 6 integers of the value 4
CustomType C( &vec2[0], 2UL, 3UL ); // Represent the std::vector as Blaze dense matrix
A = C; // Copy assignment: Set all values of matrix A and B to 4.
\endcode
// \n \subsection matrix_types_custom_matrix_alignment Alignment
//
// In case the custom matrix is specified as \c aligned the passed array must adhere to some
// alignment restrictions based on the alignment requirements of the used data type and the
// used instruction set (SSE, AVX, ...). The restriction applies to the first element of each
// row/column: In case of a row-major matrix the first element of each row must be properly
// aligned, in case of a column-major matrix the first element of each column must be properly
// aligned. For instance, if a row-major matrix is used and AVX is active the first element of
// each row must be 32-bit aligned:
\code
using blaze::CustomMatrix;
using blaze::Deallocate;
using blaze::aligned;
using blaze::padded;
using blaze::rowMajor;
int* array = blaze::allocate<int>( 40UL ); // Is guaranteed to be 32-bit aligned
CustomMatrix<int,aligned,padded,rowMajor> A( array, 5UL, 6UL, 8UL, Deallocate() );
\endcode
// In the example, the row-major matrix has six columns. However, since with AVX eight integer
// values are loaded together the matrix is padded with two additional elements. This guarantees
// that the first element of each row is 32-bit aligned. In case the alignment requirements are
// violated, a \c std::invalid_argument exception is thrown.
//
// \n \subsection matrix_types_custom_matrix_padding Padding
//
// Adding padding elements to the end of each row/column can have a significant impact on the
// performance. For instance, assuming that AVX is available, then two aligned, padded, 3x3 double
// precision matrices can be added via three SIMD addition operations:
\code
using blaze::CustomMatrix;
using blaze::Deallocate;
using blaze::allocate;
using blaze::aligned;
using blaze::padded;
typedef CustomMatrix<double,aligned,padded> CustomType;
// Creating padded custom 3x3 matrix with an additional padding element in each row
CustomType A( allocate<double>( 12UL ), 3UL, 3UL, 4UL, Deallocate() );
CustomType B( allocate<double>( 12UL ), 3UL, 3UL, 4UL, Deallocate() );
CustomType C( allocate<double>( 12UL ), 3UL, 3UL, 4UL, Deallocate() );
// ... Initialization
C = A + B; // AVX-based matrix addition
\endcode
// In this example, maximum performance is possible. However, in case no padding elements are
// inserted a scalar addition has to be used:
\code
using blaze::CustomMatrix;
using blaze::Deallocate;
using blaze::allocate;
using blaze::aligned;
using blaze::unpadded;
typedef CustomMatrix<double,aligned,unpadded> CustomType;
// Creating unpadded custom 3x3 matrix
CustomType A( allocate<double>( 12UL ), 3UL, 3UL, 4UL, Deallocate() );
CustomType B( allocate<double>( 12UL ), 3UL, 3UL, 4UL, Deallocate() );
CustomType C( allocate<double>( 12UL ), 3UL, 3UL, 4UL, Deallocate() );
// ... Initialization
C = A + B; // Scalar matrix addition
\endcode
// Note that the construction of padded and unpadded aligned matrices looks identical. However,
// in case of padded matrices, \b Blaze will zero initialize the padding element and use them
// in all computations in order to achieve maximum performance. In case of an unpadded matrix
// \b Blaze will ignore the elements with the downside that it is not possible to load a complete
// row to an AVX register, which makes it necessary to fall back to a scalar addition.
//
// The number of padding elements is required to be sufficient with respect to the available
// instruction set: In case of an aligned padded custom matrix the added padding elements must
// guarantee that the total number of elements in each row/column is a multiple of the SIMD
// vector width. In case of an unaligned padded matrix the number of padding elements can be
// greater or equal the number of padding elements of an aligned padded custom matrix. In case
// the padding is insufficient with respect to the available instruction set, a
// \c std::invalid_argument exception is thrown.
//

// \n \section matrix_operations_constructors Constructors
// <hr>
//
// Matrices are just as easy and intuitive to create as vectors. Still, there are a few rules
// to be aware of:
// - In case the last template parameter (the storage order) is omitted, the matrix is per
// default stored in row-major order.
// - The elements of a \c StaticMatrix or \c HybridMatrix are default initialized (i.e. built-in
// data types are initialized to 0, class types are initialized via the default constructor).
// - Newly allocated elements of a \c DynamicMatrix or \c CompressedMatrix remain uninitialized
// if they are of built-in type and are default constructed if they are of class type.
//
// \n \subsection matrix_operations_default_construction Default Construction
\code
using blaze::StaticMatrix;
using blaze::DynamicMatrix;
using blaze::CompressedMatrix;
// All matrices can be default constructed. Whereas the size of
// a StaticMatrix is fixed via the second and third template
// parameter, the initial size of a constructed DynamicMatrix
// or CompressedMatrix is 0.
StaticMatrix<int,2UL,2UL> M1; // Instantiation of a 2x2 integer row-major
// matrix. All elements are initialized to 0.
DynamicMatrix<float> M2; // Instantiation of a single precision dynamic
// row-major matrix with 0 rows and 0 columns.
DynamicMatrix<double,columnMajor> M3; // Instantiation of a double precision dynamic
// column-major matrix with 0 rows and 0 columns.
CompressedMatrix<int> M4; // Instantiation of a compressed integer
// row-major matrix of size 0x0.
CompressedMatrix<double,columnMajor> M5; // Instantiation of a compressed double precision
// column-major matrix of size 0x0.
\endcode
// \n \subsection matrix_operations_size_construction Construction with Specific Size
//
// The \c DynamicMatrix, \c HybridMatrix, and \c CompressedMatrix classes offer a constructor
// that allows to immediately give the matrices a specific number of rows and columns:
\code
DynamicMatrix<int> M6( 5UL, 4UL ); // Instantiation of a 5x4 dynamic row-major
// matrix. The elements are not initialized.
HybridMatrix<double,5UL,9UL> M7( 3UL, 7UL ); // Instantiation of a 3x7 hybrid row-major
// matrix. The elements are not initialized.
CompressedMatrix<float,columnMajor> M8( 8UL, 6UL ); // Instantiation of an empty 8x6 compressed
// column-major matrix.
\endcode
// Note that dense matrices (in this case \c DynamicMatrix and \c HybridMatrix) immediately
// allocate enough capacity for all matrix elements. Sparse matrices on the other hand (in this
// example \c CompressedMatrix) merely acquire the size, but don't necessarily allocate memory.
//
//
// \n \subsection matrix_operations_initialization_constructors Initialization Constructors
//
// All dense matrix classes offer a constructor for a direct, homogeneous initialization of all
// matrix elements. In contrast, for sparse matrices the predicted number of non-zero elements
// can be specified.
\code
StaticMatrix<int,4UL,3UL,columnMajor> M9( 7 ); // Instantiation of a 4x3 integer column-major
// matrix. All elements are initialized to 7.
DynamicMatrix<float> M10( 2UL, 5UL, 2.0F ); // Instantiation of a 2x5 single precision row-major
// matrix. All elements are initialized to 2.0F.
CompressedMatrix<int> M11( 3UL, 4UL, 4 ); // Instantiation of a 3x4 integer row-major
// matrix with capacity for 4 non-zero elements.
\endcode
// \n \subsection matrix_operations_array_construction Array Construction
//
// Alternatively, all dense matrix classes offer a constructor for an initialization with a
// dynamic or static array. If the matrix is initialized from a dynamic array, the constructor
// expects the dimensions of values provided by the array as first and second argument, the
// array as third argument. In case of a static array, the fixed size of the array is used:
\code
const std::unique_ptr<double[]> array1( new double[6] );
// ... Initialization of the dynamic array
blaze::StaticMatrix<double,2UL,3UL> M12( 2UL, 3UL, array1.get() );
int array2[2][2] = { { 4, -5 }, { -6, 7 } };
blaze::StaticMatrix<int,2UL,2UL,rowMajor> M13( array2 );
\endcode
// \n \subsection matrix_operations_initializer_list_construction
//
// In addition, all dense matrix classes can be directly initialized by means of an initializer
// list:
\code
blaze::DynamicMatrix<float,columnMajor> M14{ { 3.1F, 6.4F },
{ -0.9F, -1.2F },
{ 4.8F, 0.6F } };
\endcode
// \n \subsection matrix_operations_copy_construction Copy Construction
//
// All dense and sparse matrices can be created as a copy of another dense or sparse matrix.
\code
StaticMatrix<int,5UL,4UL,rowMajor> M15( M6 ); // Instantiation of the dense row-major matrix M15
// as copy of the dense row-major matrix M6.
DynamicMatrix<float,columnMajor> M16( M8 ); // Instantiation of the dense column-major matrix M16
// as copy of the sparse column-major matrix M8.
CompressedMatrix<double,columnMajor> M17( M7 ); // Instantiation of the compressed column-major matrix
// M17 as copy of the dense row-major matrix M7.
CompressedMatrix<float,rowMajor> M18( M8 ); // Instantiation of the compressed row-major matrix
// M18 as copy of the compressed column-major matrix M8.
\endcode
// Note that it is not possible to create a \c StaticMatrix as a copy of a matrix with a different
// number of rows and/or columns:
\code
StaticMatrix<int,4UL,5UL,rowMajor> M19( M6 ); // Runtime error: Number of rows and columns
// does not match!
StaticMatrix<int,4UL,4UL,columnMajor> M20( M9 ); // Compile time error: Number of columns does
// not match!
\endcode
// \n \section matrix_operations_assignment Assignment
// <hr>
//
// There are several types of assignment to dense and sparse matrices:
// \ref matrix_operations_homogeneous_assignment, \ref matrix_operations_array_assignment,
// \ref matrix_operations_copy_assignment, and \ref matrix_operations_compound_assignment.
//
//
// \n \subsection matrix_operations_homogeneous_assignment Homogeneous Assignment
//
// It is possible to assign the same value to all elements of a dense matrix. All dense matrix
// classes provide an according assignment operator:
\code
blaze::StaticMatrix<int,3UL,2UL> M1;
blaze::DynamicMatrix<double> M2;
// Setting all integer elements of the StaticMatrix to 4
M1 = 4;
// Setting all double precision elements of the DynamicMatrix to 3.5
M2 = 3.5
\endcode
// \n \subsection matrix_operations_array_assignment Array Assignment
//
// Dense matrices can also be assigned a static array:
\code
blaze::StaticMatrix<int,2UL,2UL,rowMajor> M1;
blaze::StaticMatrix<int,2UL,2UL,columnMajor> M2;
blaze::DynamicMatrix<double> M3;
int array1[2][2] = { { 1, 2 }, { 3, 4 } };
double array2[3][2] = { { 3.1, 6.4 }, { -0.9, -1.2 }, { 4.8, 0.6 } };
M1 = array1;
M2 = array1;
M3 = array2;
\endcode
// Note that the dimensions of the static array have to match the size of a \c StaticMatrix,
// whereas a \c DynamicMatrix is resized according to the array dimensions:
\f$ M3 = \left(\begin{array}{*{2}{c}}
3.1 & 6.4 \\
-0.9 & -1.2 \\
4.8 & 0.6 \\
\end{array}\right)\f$
// \n \subsection matrix_operations_initializer_list_assignment Initializer List Assignment
//
// Alternatively, it is possible to directly assign an initializer list to a dense matrix:
\code
blaze::DynamicMatrix<double> M;
M = { { 3.1, 6.4 }, { -0.9, -1.2 }, { 4.8, 0.6 } };
\endcode
// \n \subsection matrix_operations_copy_assignment Copy Assignment
//
// All kinds of matrices can be assigned to each other. The only restriction is that since a
// \c StaticMatrix cannot change its size, the assigned matrix must match both in the number of
// rows and in the number of columns.
\code
blaze::StaticMatrix<int,3UL,2UL,rowMajor> M1;
blaze::DynamicMatrix<int,rowMajor> M2( 3UL, 2UL );
blaze::DynamicMatrix<float,rowMajor> M3( 5UL, 2UL );
blaze::CompressedMatrix<int,rowMajor> M4( 3UL, 2UL );
blaze::CompressedMatrix<float,columnMajor> M5( 3UL, 2UL );
// ... Initialization of the matrices
M1 = M2; // OK: Assignment of a 3x2 dense row-major matrix to another 3x2 dense row-major matrix
M1 = M4; // OK: Assignment of a 3x2 sparse row-major matrix to a 3x2 dense row-major matrix
M1 = M3; // Runtime error: Cannot assign a 5x2 matrix to a 3x2 static matrix
M1 = M5; // OK: Assignment of a 3x2 sparse column-major matrix to a 3x2 dense row-major matrix
\endcode
// \n \subsection matrix_operations_compound_assignment Compound Assignment
//
// Compound assignment is also available for matrices: addition assignment, subtraction assignment,
// and multiplication assignment. In contrast to plain assignment, however, the number of rows
// and columns of the two operands have to match according to the arithmetic operation.
\code
blaze::StaticMatrix<int,2UL,3UL,rowMajor> M1;
blaze::DynamicMatrix<int,rowMajor> M2( 2UL, 3UL );
blaze::CompressedMatrix<float,columnMajor> M3( 2UL, 3UL );
blaze::CompressedMatrix<float,rowMajor> M4( 2UL, 4UL );
blaze::StaticMatrix<float,2UL,4UL,rowMajor> M5;
blaze::CompressedMatrix<float,rowMajor> M6( 3UL, 2UL );
// ... Initialization of the matrices
M1 += M2; // OK: Addition assignment between two row-major matrices of the same dimensions
M1 -= M3; // OK: Subtraction assignment between between a row-major and a column-major matrix
M1 += M4; // Runtime error: No compound assignment between matrices of different size
M1 -= M5; // Compilation error: No compound assignment between matrices of different size
M2 *= M6; // OK: Multiplication assignment between two row-major matrices
\endcode
// Note that the multiplication assignment potentially changes the number of columns of the
// target matrix:
\f$\left(\begin{array}{*{3}{c}}
2 & 0 & 1 \\
0 & 3 & 2 \\
\end{array}\right) \times
\left(\begin{array}{*{2}{c}}
4 & 0 \\
1 & 0 \\
0 & 3 \\
\end{array}\right) =
\left(\begin{array}{*{2}{c}}
8 & 3 \\
3 & 6 \\
\end{array}\right)\f$
// Since a \c StaticMatrix cannot change its size, only a square StaticMatrix can be used in a
// multiplication assignment with other square matrices of the same dimensions.
//
//
// \n \section matrix_operations_element_access Element Access
// <hr>
//
// The easiest way to access a specific dense or sparse matrix element is via the function call
// operator. The indices to access a matrix are zero-based:
\code
blaze::DynamicMatrix<int> M1( 4UL, 6UL );
M1(0,0) = 1;
M1(0,1) = 3;
// ...
blaze::CompressedMatrix<double> M2( 5UL, 3UL );
M2(0,2) = 4.1;
M2(1,1) = -6.3;
\endcode
// Since dense matrices allocate enough memory for all contained elements, using the function
// call operator on a dense matrix directly returns a reference to the accessed value. In case
// of a sparse matrix, if the accessed value is currently not contained in the matrix, the
// value is inserted into the matrix prior to returning a reference to the value, which can
// be much more expensive than the direct access to a dense matrix. Consider the following
// example:
\code
blaze::CompressedMatrix<int> M1( 4UL, 4UL );
for( size_t i=0UL; i<M1.rows(); ++i ) {
for( size_t j=0UL; j<M1.columns(); ++j ) {
... = M1(i,j);
}
}
\endcode
// Although the compressed matrix is only used for read access within the for loop, using the
// function call operator temporarily inserts 16 non-zero elements into the matrix. Therefore,
// all matrices (sparse as well as dense) offer an alternate way via the \c begin(), \c cbegin(),
// \c end() and \c cend() functions to traverse all contained elements by iterator. Note that
// it is not possible to traverse all elements of the matrix, but that it is only possible to
// traverse elements in a row/column-wise fashion. In case of a non-const matrix, \c begin() and
// \c end() return an \c Iterator, which allows a manipulation of the non-zero value, in case of
// a constant matrix or in case \c cbegin() or \c cend() are used a \c ConstIterator is returned:
\code
using blaze::CompressedMatrix;
CompressedMatrix<int,rowMajor> M1( 4UL, 6UL );
// Traversing the matrix by Iterator
for( size_t i=0UL; i<A.rows(); ++i ) {
for( CompressedMatrix<int,rowMajor>::Iterator it=A.begin(i); it!=A.end(i); ++it ) {
it->value() = ...; // OK: Write access to the value of the non-zero element.
... = it->value(); // OK: Read access to the value of the non-zero element.
it->index() = ...; // Compilation error: The index of a non-zero element cannot be changed.
... = it->index(); // OK: Read access to the index of the non-zero element.
}
}
// Traversing the matrix by ConstIterator
for( size_t i=0UL; i<A.rows(); ++i ) {
for( CompressedMatrix<int,rowMajor>::ConstIterator it=A.cbegin(i); it!=A.cend(i); ++it ) {
it->value() = ...; // Compilation error: Assignment to the value via a ConstIterator is invalid.
... = it->value(); // OK: Read access to the value of the non-zero element.
it->index() = ...; // Compilation error: The index of a non-zero element cannot be changed.
... = it->index(); // OK: Read access to the index of the non-zero element.
}
}
\endcode
// Note that \c begin(), \c cbegin(), \c end(), and \c cend() are also available as free functions:
\code
for( size_t i=0UL; i<A.rows(); ++i ) {
for( CompressedMatrix<int,rowMajor>::Iterator it=begin( A, i ); it!=end( A, i ); ++it ) {
// ...
}
}
for( size_t i=0UL; i<A.rows(); ++i ) {
for( CompressedMatrix<int,rowMajor>::ConstIterator it=cbegin( A, i ); it!=cend( A, i ); ++it ) {
// ...
}
}
\endcode
// \n \section matrix_operations_element_insertion Element Insertion
// <hr>
//
// Whereas a dense matrix always provides enough capacity to store all matrix elements, a sparse
// matrix only stores the non-zero elements. Therefore it is necessary to explicitly add elements
// to the matrix. The first possibility to add elements to a sparse matrix is the function call
// operator:
\code
using blaze::CompressedMatrix;
CompressedMatrix<int> M1( 3UL, 4UL );
M1(1,2) = 9;
\endcode
// In case the element at the given position is not yet contained in the sparse matrix, it is
// automatically inserted. Otherwise the old value is replaced by the new value 2. The operator
// returns a reference to the sparse vector element.\n
// An alternative is the \c set() function: In case the element is not yet contained in the matrix
// the element is inserted, else the element's value is modified:
\code
// Insert or modify the value at position (2,0)
M1.set( 2, 0, 1 );
\endcode
// However, insertion of elements can be better controlled via the \c insert() function. In
// contrast to the function call operator and the \c set() function it emits an exception in case
// the element is already contained in the matrix. In order to check for this case, the \c find()
// function can be used:
\code
// In case the element at position (2,3) is not yet contained in the matrix it is inserted
// with a value of 4.
if( M1.find( 2, 3 ) == M1.end( 2 ) )
M1.insert( 2, 3, 4 );
\endcode
// Although the \c insert() function is very flexible, due to performance reasons it is not
// suited for the setup of large sparse matrices. A very efficient, yet also very low-level
// way to fill a sparse matrix is the \c append() function. It requires the sparse matrix to
// provide enough capacity to insert a new element in the specified row. Additionally, the
// index of the new element must be larger than the index of the previous element in the same
// row. Violating these conditions results in undefined behavior!
\code
M1.reserve( 0, 3 ); // Reserving space for three non-zero elements in row 0
M1.append( 0, 1, 2 ); // Appending the element 2 in row 0 at column index 1
M1.append( 0, 2, -4 ); // Appending the element -4 in row 0 at column index 2
// ...
\endcode
// The most efficient way to fill a sparse matrix with elements, however, is a combination of
// \c reserve(), \c append(), and the \c finalize() function:
\code
blaze::CompressedMatrix<int> M1( 3UL, 5UL );
M1.reserve( 3 ); // Reserving enough space for 3 non-zero elements
M1.append( 0, 1, 1 ); // Appending the value 1 in row 0 with column index 1
M1.finalize( 0 ); // Finalizing row 0
M1.append( 1, 1, 2 ); // Appending the value 2 in row 1 with column index 1
M1.finalize( 1 ); // Finalizing row 1
M1.append( 2, 0, 3 ); // Appending the value 3 in row 2 with column index 0
M1.finalize( 2 ); // Finalizing row 2
\endcode
// \n \section matrix_operations_member_functions Member Functions
// <hr>
//
// \subsection matrix_operations_rows .rows()
//
// The current number of rows of a matrix can be acquired via the \c rows() member function:
\code
// Instantiating a dynamic matrix with 10 rows and 8 columns
blaze::DynamicMatrix<int> M1( 10UL, 8UL );
M1.rows(); // Returns 10
// Instantiating a compressed matrix with 8 rows and 12 columns
blaze::CompressedMatrix<double> M2( 8UL, 12UL );
M2.rows(); // Returns 8
\endcode
// Alternatively, the free functions \c rows() can be used to query the current number of rows of
// a matrix. In contrast to the member function, the free function can also be used to query the
// number of rows of a matrix expression:
\code
rows( M1 ); // Returns 10, i.e. has the same effect as the member function
rows( M2 ); // Returns 8, i.e. has the same effect as the member function
rows( M1 * M2 ); // Returns 10, i.e. the number of rows of the resulting matrix
\endcode
// \n \subsection matrix_operations_columns .columns()
//
// The current number of columns of a matrix can be acquired via the \c columns() member function:
\code
// Instantiating a dynamic matrix with 6 rows and 8 columns
blaze::DynamicMatrix<int> M1( 6UL, 8UL );
M1.columns(); // Returns 8
// Instantiating a compressed matrix with 8 rows and 7 columns
blaze::CompressedMatrix<double> M2( 8UL, 7UL );
M2.columns(); // Returns 7
\endcode
// There is also a free function \c columns() available, which can also be used to query the number
// of columns of a matrix expression:
\code
columns( M1 ); // Returns 8, i.e. has the same effect as the member function
columns( M2 ); // Returns 7, i.e. has the same effect as the member function
columns( M1 * M2 ); // Returns 7, i.e. the number of columns of the resulting matrix
\endcode
// \n \subsection matrix_operations_capacity .capacity()
//
// The \c capacity() member function returns the internal capacity of a dense or sparse matrix.
// Note that the capacity of a matrix doesn't have to be equal to the size of a matrix. In case of
// a dense matrix the capacity will always be greater or equal than the total number of elements
// of the matrix. In case of a sparse matrix, the capacity will usually be much less than the
// total number of elements.
\code
blaze::DynamicMatrix<float> M1( 5UL, 7UL );
blaze::StaticMatrix<float,7UL,4UL> M2;
M1.capacity(); // Returns at least 35
M2.capacity(); // Returns at least 28
\endcode
// There is also a free function \c capacity() available to query the capacity. However, please
// note that this function cannot be used to query the capacity of a matrix expression:
\code
capacity( M1 ); // Returns at least 35, i.e. has the same effect as the member function
capacity( M2 ); // Returns at least 28, i.e. has the same effect as the member function
capacity( M1 * M2 ); // Compilation error!
\endcode
// \n \subsection matrix_operations_nonzeros .nonZeros()
//
// For both dense and sparse matrices the current number of non-zero elements can be queried
// via the \c nonZeros() member function. In case of matrices there are two flavors of the
// \c nonZeros() function: One returns the total number of non-zero elements in the matrix,
// the second returns the number of non-zero elements in a specific row (in case of a row-major
// matrix) or column (in case of a column-major matrix). Sparse matrices directly return their
// number of non-zero elements, dense matrices traverse their elements and count the number of
// non-zero elements.
\code
blaze::DynamicMatrix<int,rowMajor> M1( 3UL, 5UL );
// ... Initializing the dense matrix
M1.nonZeros(); // Returns the total number of non-zero elements in the dense matrix
M1.nonZeros( 2 ); // Returns the number of non-zero elements in row 2
\endcode
\code
blaze::CompressedMatrix<double,columnMajor> M2( 4UL, 7UL );
// ... Initializing the sparse matrix
M2.nonZeros(); // Returns the total number of non-zero elements in the sparse matrix
M2.nonZeros( 3 ); // Returns the number of non-zero elements in column 3
\endcode
// The free \c nonZeros() function can also be used to query the number of non-zero elements in a
// matrix expression. However, the result is not the exact number of non-zero elements, but may be
// a rough estimation:
\code
nonZeros( M1 ); // Has the same effect as the member function
nonZeros( M1, 2 ); // Has the same effect as the member function

\endcode
// The function works for both \c rowMajor and \c columnMajor matrices. Note, however, that the

//
// Furthermore, \c lu() can be used with adaptors. For instance, the following example demonstrates

//
// Adaptors act as wrappers around the general \ref matrix_types. They adapt the interface of the
// matrices such that certain invariants are preserved. Due to this adaptors can provide a compile
// time guarantee of certain properties, which can be exploited for optimized performance.
//
// The \b Blaze library provides a total of 9 different adaptors:

// </ul>
// </li>
// </ul>
//
// In combination with the general matrix types, \b Blaze provides a total of 40 different matrix
// types that make it possible to exactly adapt the type of matrix to every specific problem.
//
//
// \n \section adaptors_examples Examples
// <hr>
//
// The following code examples give an impression on the use of adaptors. The first example shows
// the multiplication between two lower matrices:
\code
using blaze::DynamicMatrix;
using blaze::LowerMatrix;
using blaze::rowMajor;
using blaze::columnMajor;
LowerMatrix< DynamicMatrix<double,rowMajor> > A;
LowerMatrix< DynamicMatrix<double,columnMajor> > B;
DynamicMatrix<double,columnMajor> C;
// ... Resizing and initialization
C = A * B;
\endcode
// When multiplying two matrices, at least one of which is triangular, \b Blaze can exploit the
// fact that either the lower or upper part of the matrix contains only default elements and
// restrict the algorithm to the non-zero elements. Thus the adaptor provides a significant
// performance advantage in comparison to a general matrix multiplication, especially for large
// matrices.
//
// The second example shows the \c SymmetricMatrix adaptor in a row-major dense matrix/sparse
// vector multiplication:
\code
using blaze::DynamicMatrix;
using blaze::DynamicVector;
using blaze::CompressedVector;
using blaze::rowMajor;
using blaze::columnVector;
SymmetricMatrix< DynamicMatrix<double,rowMajor> > A;
CompressedVector<double,columnVector> x;
DynamicVector<double,columnVector> y;
// ... Resizing and initialization
y = A * x;
\endcode
// In this example it is not intuitively apparent that using a row-major matrix is not the best
// possible choice in terms of performance since the computation cannot be vectorized. Choosing
// a column-major matrix instead, however, would enable a vectorized computation. Therefore
// \b Blaze exploits the fact that \c A is symmetric, selects the best suited storage order and
// evaluates the multiplication as
\code
y = trans( A ) * x;
\endcode
// which significantly increases the performance.

// \n \section adaptors_symmetric_matrices_general Symmetric Matrices
// <hr>
//
// In contrast to general matrices, which have no restriction in their number of rows and columns
// and whose elements can have any value, symmetric matrices provide the compile time guarantee
// to be square matrices with pair-wise identical values. Mathematically, this means that a
// symmetric matrix is always equal to its transpose (\f$ A = A^T \f$) and that all non-diagonal
// values have an identical counterpart (\f$ a_{ij} == a_{ji} \f$). This symmetry property can
// be exploited to provide higher efficiency and/or lower memory consumption. Within the \b Blaze
// library, symmetric matrices are realized by the \ref adaptors_symmetric_matrices_symmetricmatrix
// class template.
//
//
// \n \section adaptors_symmetric_matrices_symmetricmatrix SymmetricMatrix
// <hr>
//
// The SymmetricMatrix class template is an adapter for existing dense and sparse matrix types.
// It inherits the properties and the interface of the given matrix type \c MT and extends it
// by enforcing the additional invariant of symmetry (i.e. the matrix is always equal to its
// transpose \f$ A = A^T \f$). It can be included via the header file
\code
#include <blaze/math/SymmetricMatrix.h>
\endcode
// The type of the adapted matrix can be specified via template parameter:
\code
template< typename MT >
class SymmetricMatrix;
\endcode
// \c MT specifies the type of the matrix to be adapted. SymmetricMatrix can be used with any
// non-cv-qualified, non-reference, non-pointer, non-expression dense or sparse matrix type. Note
// that the given matrix type must be either resizable (as for instance blaze::HybridMatrix or
// blaze::DynamicMatrix) or must be square at compile time (as for instance blaze::StaticMatrix).
//
// The following examples give an impression of several possible symmetric matrices:
\code
using blaze::unaligned;
using blaze::unpadded;
using blaze::rowMajor;
using blaze::columnMajor;
// Definition of a 3x3 row-major dense symmetric matrix with static memory
blaze::SymmetricMatrix< blaze::StaticMatrix<int,3UL,3UL,rowMajor> > A;
// Definition of a resizable column-major dense symmetric matrix based on HybridMatrix
blaze::SymmetricMatrix< blaze::HybridMatrix<float,4UL,4UL,columnMajor> B;
// Definition of a resizable row-major dense symmetric matrix based on DynamicMatrix
blaze::SymmetricMatrix< blaze::DynamicMatrix<double,rowMajor> > C;
// Definition of a fixed size row-major dense symmetric matrix based on CustomMatrix

// Definition of a compressed row-major single precision symmetric matrix
blaze::SymmetricMatrix< blaze::CompressedMatrix<float,blaze::rowMajor> > E;
\endcode
// The storage order of a symmetric matrix is depending on the storage order of the adapted matrix
// type \c MT. In case the adapted matrix is stored in a row-wise fashion (i.e. is specified as
// blaze::rowMajor), the symmetric matrix will also be a row-major matrix. Otherwise, if the
// adapted matrix is column-major (i.e. is specified as blaze::columnMajor), the symmetric matrix
// will also be a column-major matrix.
//
//
// \n \section adaptors_symmetric_matrices_special_properties Special Properties of Symmetric Matrices
// <hr>
//
// A symmetric matrix is used exactly like a matrix of the underlying, adapted matrix type \c MT.

// some important exceptions resulting from the symmetry constraint:
//
// -# <b>\ref adaptors_symmetric_matrices_square</b>
// -# <b>\ref adaptors_symmetric_matrices_symmetry</b>
// -# <b>\ref adaptors_symmetric_matrices_initialization</b>
//
// \n \subsection adaptors_symmetric_matrices_square Symmetric Matrices Must Always be Square!
//
// In case a resizable matrix is used (as for instance blaze::HybridMatrix, blaze::DynamicMatrix,
// or blaze::CompressedMatrix), this means that the according constructors, the \c resize() and
// the \c extend() functions only expect a single parameter, which specifies both the number of
// rows and columns, instead of two (one for the number of rows and one for the number of columns):
\code
using blaze::DynamicMatrix;
using blaze::SymmetricMatrix;
using blaze::rowMajor;
// Default constructed, default initialized, row-major 3x3 symmetric dynamic matrix
SymmetricMatrix< DynamicMatrix<double,rowMajor> > A( 3 );
// Resizing the matrix to 5x5
A.resize( 5 );
// Extending the number of rows and columns by 2, resulting in a 7x7 matrix
A.extend( 2 );
\endcode
// In case a matrix with a fixed size is used (as for instance blaze::StaticMatrix), the number
// of rows and number of columns must be specified equally:
\code
using blaze::StaticMatrix;
using blaze::SymmetricMatrix;
using blaze::columnMajor;
// Correct setup of a fixed size column-major 3x3 symmetric static matrix
SymmetricMatrix< StaticMatrix<int,3UL,3UL,columnMajor> > A;
// Compilation error: the provided matrix type is not a square matrix type
SymmetricMatrix< StaticMatrix<int,3UL,4UL,columnMajor> > B;
\endcode
// \n \subsection adaptors_symmetric_matrices_symmetry The Symmetric Property is Always Enforced!
//
// This means that modifying the element \f$ a_{ij} \f$ of a symmetric matrix also modifies its
// counterpart element \f$ a_{ji} \f$. Also, it is only possible to assign matrices that are
// symmetric themselves:
\code
using blaze::CompressedMatrix;
using blaze::DynamicMatrix;
using blaze::StaticMatrix;
using blaze::SymmetricMatrix;
using blaze::rowMajor;
// Default constructed, row-major 3x3 symmetric compressed matrix
SymmetricMatrix< CompressedMatrix<double,rowMajor> > A( 3 );
// Initializing three elements via the function call operator
A(0,0) = 1.0; // Initialization of the diagonal element (0,0)
A(0,2) = 2.0; // Initialization of the elements (0,2) and (2,0)
// Inserting three more elements via the insert() function
A.insert( 1, 1, 3.0 ); // Inserting the diagonal element (1,1)
A.insert( 1, 2, 4.0 ); // Inserting the elements (1,2) and (2,1)
// Access via a non-const iterator
*A.begin(1UL) = 10.0; // Modifies both elements (1,0) and (0,1)
// Erasing elements via the erase() function
A.erase( 0, 0 ); // Erasing the diagonal element (0,0)
A.erase( 0, 2 ); // Erasing the elements (0,2) and (2,0)
// Construction from a symmetric dense matrix
StaticMatrix<double,3UL,3UL> B{ { 3.0, 8.0, -2.0 },
{ 8.0, 0.0, -1.0 },
{ -2.0, -1.0, 4.0 } };
SymmetricMatrix< DynamicMatrix<double,rowMajor> > C( B ); // OK
// Assignment of a non-symmetric dense matrix
StaticMatrix<double,3UL,3UL> D{ { 3.0, 7.0, -2.0 },
{ 8.0, 0.0, -1.0 },
{ -2.0, -1.0, 4.0 } };
C = D; // Throws an exception; symmetric invariant would be violated!
\endcode
// The same restriction also applies to the \c append() function for sparse matrices: Appending
// the element \f$ a_{ij} \f$ additionally inserts the element \f$ a_{ji} \f$ into the matrix.
// Despite the additional insertion, the \c append() function still provides the most efficient
// way to set up a symmetric sparse matrix. In order to achieve the maximum efficiency, the
// capacity of the individual rows/columns of the matrix should to be specifically prepared with
// \c reserve() calls:
\code
using blaze::CompressedMatrix;
using blaze::SymmetricMatrix;
using blaze::rowMajor;
// Setup of the symmetric matrix
//
// ( 0 1 3 )
// A = ( 1 2 0 )
// ( 3 0 0 )
//
SymmetricMatrix< CompressedMatrix<double,rowMajor> > A( 3 );
A.reserve( 5 ); // Reserving enough space for 5 non-zero elements
A.reserve( 0, 2 ); // Reserving two non-zero elements in the first row
A.reserve( 1, 2 ); // Reserving two non-zero elements in the second row
A.reserve( 2, 1 ); // Reserving a single non-zero element in the third row
A.append( 0, 1, 1.0 ); // Appending the value 1 at position (0,1) and (1,0)
A.append( 1, 1, 2.0 ); // Appending the value 2 at position (1,1)
A.append( 2, 0, 3.0 ); // Appending the value 3 at position (2,0) and (0,2)
\endcode
// The symmetry property is also enforced for symmetric custom matrices: In case the given array
// of elements does not represent a symmetric matrix, a \c std::invalid_argument exception is
// thrown:
\code
using blaze::CustomMatrix;
using blaze::SymmetricMatrix;
using blaze::unaligned;
using blaze::unpadded;
using blaze::rowMajor;
typedef SymmetricMatrix< CustomMatrix<double,unaligned,unpadded,rowMajor> > CustomSymmetric;
// Creating a 3x3 symmetric custom matrix from a properly initialized array

2.0, 3.0, 5.0,
4.0, 5.0, 6.0 };
CustomSymmetric A( array, 3UL ); // OK
// Attempt to create a second 3x3 symmetric custom matrix from an uninitialized array
CustomSymmetric B( new double[9UL], 3UL, blaze::ArrayDelete() ); // Throws an exception
\endcode
// Finally, the symmetry property is enforced for views (rows, columns, submatrices, ...) on the
// symmetric matrix. The following example demonstrates that modifying the elements of an entire
// row of the symmetric matrix also affects the counterpart elements in the according column of
// the matrix:
\code
using blaze::DynamicMatrix;
using blaze::SymmetricMatrix;
// Setup of the symmetric matrix
//
// ( 0 1 0 2 )
// A = ( 1 3 4 0 )
// ( 0 4 0 5 )
// ( 2 0 5 0 )
//
SymmetricMatrix< DynamicMatrix<int> > A( 4 );
A(0,1) = 1;
A(0,3) = 2;
A(1,1) = 3;
A(1,2) = 4;
A(2,3) = 5;
// Setting all elements in the 1st row to 0 results in the matrix
//
// ( 0 0 0 2 )
// A = ( 0 0 0 0 )
// ( 0 0 0 5 )
// ( 2 0 5 0 )
//
row( A, 1 ) = 0;
\endcode
// The next example demonstrates the (compound) assignment to submatrices of symmetric matrices.
// Since the modification of element \f$ a_{ij} \f$ of a symmetric matrix also modifies the
// element \f$ a_{ji} \f$, the matrix to be assigned must be structured such that the symmetry
// of the symmetric matrix is preserved. Otherwise a \c std::invalid_argument exception is
// thrown:
\code
using blaze::DynamicMatrix;
using blaze::SymmetricMatrix;
// Setup of two default 4x4 symmetric matrices
SymmetricMatrix< DynamicMatrix<int> > A1( 4 ), A2( 4 );
// Setup of the 3x2 dynamic matrix
//
// ( 1 2 )
// B = ( 3 4 )
// ( 5 6 )
//
DynamicMatrix<int> B{ { 1, 2 }, { 3, 4 }, { 5, 6 } };
// OK: Assigning B to a submatrix of A1 such that the symmetry can be preserved
//
// ( 0 0 1 2 )
// A1 = ( 0 0 3 4 )
// ( 1 3 5 6 )
// ( 2 4 6 0 )
//
submatrix( A1, 0UL, 2UL, 3UL, 2UL ) = B; // OK
// Error: Assigning B to a submatrix of A2 such that the symmetry cannot be preserved!
// The elements marked with X cannot be assigned unambiguously!
//
// ( 0 1 2 0 )
// A2 = ( 1 3 X 0 )
// ( 2 X 6 0 )
// ( 0 0 0 0 )
//
submatrix( A2, 0UL, 1UL, 3UL, 2UL ) = B; // Assignment throws an exception!
\endcode
// \n \subsection adaptors_symmetric_matrices_initialization The Elements of a Dense Symmetric Matrix are Always Default Initialized!
//
// Although this results in a small loss of efficiency (especially in case all default values are

using blaze::DynamicMatrix;
using blaze::SymmetricMatrix;
// Uninitialized, 5x5 row-major dynamic matrix
DynamicMatrix<int,rowMajor> A( 5, 5 );
// Default initialized, 5x5 row-major symmetric dynamic matrix

// \n \section adaptors_symmetric_matrices_performance Performance Considerations
// <hr>
//
// When the symmetric property of a matrix is known beforehands using the SymmetricMatrix adaptor
// instead of a general matrix can be a considerable performance advantage. The \b Blaze library
// tries to exploit the properties of symmetric matrices whenever possible. However, there are
// also situations when using a symmetric matrix introduces some overhead. The following examples
// demonstrate several situations where symmetric matrices can positively or negatively impact
// performance.
//
// \n \subsection adaptors_symmetric_matrices_matrix_matrix_multiplication Positive Impact: Matrix/Matrix Multiplication
//
// When multiplying two matrices, at least one of which is symmetric, \b Blaze can exploit the fact
// that \f$ A = A^T \f$ and choose the fastest and most suited combination of storage orders for the
// multiplication. The following example demonstrates this by means of a dense matrix/sparse matrix
// multiplication:
\code
using blaze::DynamicMatrix;
using blaze::SymmetricMatrix;
using blaze::rowMajor;
using blaze::columnMajor;
SymmetricMatrix< DynamicMatrix<double,rowMajor> > A;
SymmetricMatrix< CompressedMatrix<double,columnMajor> > B;
DynamicMatrix<double,columnMajor> C;
// ... Resizing and initialization
C = A * B;
\endcode
// Intuitively, the chosen combination of a row-major and a column-major matrix is the most suited
// for maximum performance. However, \b Blaze evaluates the multiplication as
\code
C = A * trans( B );
\endcode
// which significantly increases the performance since in contrast to the original formulation the
// optimized form can be vectorized. Therefore, in the context of matrix multiplications, using the
// SymmetricMatrix adapter is obviously an advantage.
//
// \n \subsection adaptors_symmetric_matrices_matrix_vector_multiplication Positive Impact: Matrix/Vector Multiplication
//
// A similar optimization is possible in case of matrix/vector multiplications:
\code
using blaze::DynamicMatrix;
using blaze::DynamicVector;
using blaze::CompressedVector;
using blaze::rowMajor;
using blaze::columnVector;
SymmetricMatrix< DynamicMatrix<double,rowMajor> > A;
CompressedVector<double,columnVector> x;
DynamicVector<double,columnVector> y;
// ... Resizing and initialization
y = A * x;
\endcode
// In this example it is not intuitively apparent that using a row-major matrix is not the best
// possible choice in terms of performance since the computation cannot be vectorized. Choosing
// a column-major matrix instead, however, would enable a vectorized computation. Therefore
// \b Blaze exploits the fact that \c A is symmetric, selects the best suited storage order and
// evaluates the multiplication as
\code
y = trans( A ) * x;
\endcode
// which also significantly increases the performance.
//
// \n \subsection adaptors_symmetric_matrices_views Positive Impact: Row/Column Views on Column/Row-Major Matrices
//
// Another example is the optimization of a row view on a column-major symmetric matrix:
\code
using blaze::DynamicMatrix;
using blaze::SymmetricMatrix;
using blaze::Row;
using blaze::rowMajor;
using blaze::columnMajor;
typedef SymmetricMatrix< DynamicMatrix<double,columnMajor> > DynamicSymmetric;
DynamicSymmetric A( 10UL );
Row<DynamicSymmetric> row5 = row( A, 5UL );
\endcode
// Usually, a row view on a column-major matrix results in a considerable performance decrease in
// comparison to a row view on a row-major matrix due to the non-contiguous storage of the matrix
// elements. However, in case of symmetric matrices, \b Blaze instead uses the according column of
// the matrix, which provides the same performance as if the matrix would be row-major. Note that
// this also works for column views on row-major matrices, where \b Blaze can use the according
// row instead of a column in order to provide maximum performance.
//
// \n \subsection adaptors_symmetric_matrices_assignment Negative Impact: Assignment of a General Matrix
//
// In contrast to using a symmetric matrix on the right-hand side of an assignment (i.e. for read
// access), which introduces absolutely no performance penalty, using a symmetric matrix on the
// left-hand side of an assignment (i.e. for write access) may introduce additional overhead when
// it is assigned a general matrix, which is not symmetric at compile time:
\code
using blaze::DynamicMatrix;
using blaze::SymmetricMatrix;
SymmetricMatrix< DynamicMatrix<double> > A, C;
DynamicMatrix<double> B;
B = A; // Only read-access to the symmetric matrix; no performance penalty
C = A; // Assignment of a symmetric matrix to another symmetric matrix; no runtime overhead
C = B; // Assignment of a general matrix to a symmetric matrix; some runtime overhead
\endcode
// When assigning a general, potentially not symmetric matrix to a symmetric matrix it is necessary
// to check whether the matrix is symmetric at runtime in order to guarantee the symmetry property
// of the symmetric matrix. In case it turns out to be symmetric, it is assigned as efficiently as
// possible, if it is not, an exception is thrown. In order to prevent this runtime overhead it is
// therefore generally advisable to assign symmetric matrices to other symmetric matrices.\n
// In this context it is especially noteworthy that in contrast to additions and subtractions the
// multiplication of two symmetric matrices does not necessarily result in another symmetric matrix:
\code
SymmetricMatrix< DynamicMatrix<double> > A, B, C;
C = A + B; // Results in a symmetric matrix; no runtime overhead
C = A - B; // Results in a symmetric matrix; no runtime overhead
C = A * B; // Is not guaranteed to result in a symmetric matrix; some runtime overhead
\endcode

// \n \section adaptors_hermitian_matrices_general Hermitian Matrices
// <hr>
//
// In addition to symmetric matrices, \b Blaze also provides an adaptor for Hermitian matrices.
// Hermitian matrices provide the compile time guarantee to be square matrices with pair-wise
// conjugate complex values. Mathematically, this means that an Hermitian matrix is always equal
// to its conjugate transpose (\f$ A = \overline{A^T} \f$) and that all non-diagonal values have
// a complex conjugate counterpart (\f$ a_{ij} == \overline{a_{ji}} \f$). Within the \b Blaze
// library, Hermitian matrices are realized by the \ref adaptors_hermitian_matrices_hermitianmatrix
// class template.
//
//
// \n \section adaptors_hermitian_matrices_hermitianmatrix HermitianMatrix
// <hr>
//
// The HermitianMatrix class template is an adapter for existing dense and sparse matrix types.
// It inherits the properties and the interface of the given matrix type \c MT and extends it by
// enforcing the additional invariant of Hermitian symmetry (i.e. the matrix is always equal to
// its conjugate transpose \f$ A = \overline{A^T} \f$). It can be included via the header file
\code
#include <blaze/math/HermitianMatrix.h>
\endcode
// The type of the adapted matrix can be specified via template parameter:
\code
template< typename MT >
class HermitianMatrix;
\endcode
// \c MT specifies the type of the matrix to be adapted. HermitianMatrix can be used with any
// non-cv-qualified, non-reference, non-pointer, non-expression dense or sparse matrix type. Also,
// the given matrix type must have numeric element types (i.e. all integral types except \c bool,
// floating point and complex types). Note that the given matrix type must be either resizable (as
// for instance blaze::HybridMatrix or blaze::DynamicMatrix) or must be square at compile time (as
// for instance blaze::StaticMatrix).
//
// The following examples give an impression of several possible Hermitian matrices:
\code
using blaze::unaligned;
using blaze::unpadded;
using blaze::rowMajor;
using blaze::columnMajor;
// Definition of a 3x3 row-major dense Hermitian matrix with static memory
blaze::HermitianMatrix< blaze::StaticMatrix<int,3UL,3UL,rowMajor> > A;
// Definition of a resizable column-major dense Hermitian matrix based on HybridMatrix
blaze::HermitianMatrix< blaze::HybridMatrix<float,4UL,4UL,columnMajor> B;
// Definition of a resizable row-major dense Hermitian matrix based on DynamicMatrix
blaze::HermitianMatrix< blaze::DynamicMatrix<std::complex<double>,rowMajor> > C;
// Definition of a fixed size row-major dense Hermitian matrix based on CustomMatrix
blaze::HermitianMatrix< blaze::CustomMatrix<double,unaligned,unpadded,rowMajor> > D;
// Definition of a compressed row-major single precision complex Hermitian matrix
blaze::HermitianMatrix< blaze::CompressedMatrix<std::complex<float>,rowMajor> > E;
\endcode
// The storage order of a Hermitian matrix is depending on the storage order of the adapted matrix
// type \c MT. In case the adapted matrix is stored in a row-wise fashion (i.e. is specified as
// blaze::rowMajor), the Hermitian matrix will also be a row-major matrix. Otherwise, if the
// adapted matrix is column-major (i.e. is specified as blaze::columnMajor), the Hermitian matrix
// will also be a column-major matrix.
//
//
// \n \section adaptors_hermitian_matrices_vs_symmetric_matrices Hermitian Matrices vs. Symmetric Matrices
//
// The blaze::HermitianMatrix adaptor and the blaze::SymmetricMatrix adaptor share several traits.
// However, there are a couple of differences, both from a mathematical point of view as well as
// from an implementation point of view.
//
// From a mathematical point of view, a matrix is called symmetric when it is equal to its
// transpose (\f$ A = A^T \f$) and it is called Hermitian when it is equal to its conjugate
// transpose (\f$ A = \overline{A^T} \f$). For matrices of real values, however, these two
// conditions coincide, which means that symmetric matrices of real values are also Hermitian
// and Hermitian matrices of real values are also symmetric.
//
// From an implementation point of view, \b Blaze restricts Hermitian matrices to numeric data
// types (i.e. all integral types except \c bool, floating point and complex types), whereas
// symmetric matrices can also be block matrices (i.e. can have vector or matrix elements).
// For built-in element types, the HermitianMatrix adaptor behaves exactly like the according
// SymmetricMatrix implementation. For complex element types, however, the Hermitian property
// is enforced (see also \ref adaptors_hermitian_matrices_hermitian).
\code
using blaze::DynamicMatrix;
using blaze::DynamicVector;
using blaze::HermitianMatrix;
using blaze::SymmetricMatrix;
// The following two matrices provide an identical experience (including performance)
HermitianMatrix< DynamicMatrix<double> > A; // Both Hermitian and symmetric
SymmetricMatrix< DynamicMatrix<double> > B; // Both Hermitian and symmetric
// The following two matrices will behave differently
HermitianMatrix< DynamicMatrix< complex<double> > > C; // Only Hermitian
SymmetricMatrix< DynamicMatrix< complex<double> > > D; // Only symmetric
// Hermitian block matrices are not allowed
HermitianMatrix< DynamicMatrix< DynamicVector<double> > > E; // Compilation error!
SymmetricMatrix< DynamicMatrix< DynamicVector<double> > > F; // Symmetric block matrix
\endcode
// \n \section adaptors_hermitian_matrices_special_properties Special Properties of Hermitian Matrices
// <hr>
//
// A Hermitian matrix is used exactly like a matrix of the underlying, adapted matrix type \c MT.
// It also provides (nearly) the same interface as the underlying matrix type. However, there are
// some important exceptions resulting from the Hermitian symmetry constraint:
//
// -# <b>\ref adaptors_hermitian_matrices_square</b>
// -# <b>\ref adaptors_hermitian_matrices_hermitian</b>
// -# <b>\ref adaptors_hermitian_matrices_initialization</b>
//
// \n \subsection adaptors_hermitian_matrices_square Hermitian Matrices Must Always be Square!
//
// In case a resizable matrix is used (as for instance blaze::HybridMatrix, blaze::DynamicMatrix,
// or blaze::CompressedMatrix), this means that the according constructors, the \c resize() and
// the \c extend() functions only expect a single parameter, which specifies both the number of
// rows and columns, instead of two (one for the number of rows and one for the number of columns):
\code
using blaze::DynamicMatrix;
using blaze::HermitianMatrix;
using blaze::rowMajor;
// Default constructed, default initialized, row-major 3x3 Hermitian dynamic matrix
HermitianMatrix< DynamicMatrix<std::complex<double>,rowMajor> > A( 3 );
// Resizing the matrix to 5x5
A.resize( 5 );
// Extending the number of rows and columns by 2, resulting in a 7x7 matrix
A.extend( 2 );
\endcode
// In case a matrix with a fixed size is used (as for instance blaze::StaticMatrix), the number
// of rows and number of columns must be specified equally:
\code
using blaze::StaticMatrix;
using blaze::HermitianMatrix;
using blaze::columnMajor;
// Correct setup of a fixed size column-major 3x3 Hermitian static matrix
HermitianMatrix< StaticMatrix<std::complex<float>,3UL,3UL,columnMajor> > A;
// Compilation error: the provided matrix type is not a square matrix type
HermitianMatrix< StaticMatrix<std::complex<float>,3UL,4UL,columnMajor> > B;
\endcode
// \n \subsection adaptors_hermitian_matrices_hermitian The Hermitian Property is Always Enforced!
//
// This means that the following properties of a Hermitian matrix are always guaranteed:
//
// - The diagonal elements are real numbers, i.e. the imaginary part is zero
// - Element \f$ a_{ij} \f$ is always the complex conjugate of element \f$ a_{ji} \f$
//
// Thus modifying the element \f$ a_{ij} \f$ of a Hermitian matrix also modifies its
// counterpart element \f$ a_{ji} \f$. Also, it is only possible to assign matrices that
// are Hermitian themselves:
\code
using blaze::CompressedMatrix;
using blaze::DynamicMatrix;
using blaze::StaticMatrix;
using blaze::HermitianMatrix;
using blaze::rowMajor;
typedef std::complex<double> cplx;

using blaze::rowMajor;

A.append( 1, 1, cplx( 2.0, 0.0 ) ); // Appending an element at position (1,1)
A.append( 2, 0, cplx( 3.0, 4.0 ) ); // Appending an element at position (2,0) and (0,2)
\endcode
// The Hermitian property is also enforced for Hermitian custom matrices: In case the given array
// of elements does not represent a Hermitian matrix, a \c std::invalid_argument exception is

\endcode
// Finally, the Hermitian property is enforced for views (rows, columns, submatrices, ...) on the

// \n \section adaptors_hermitian_matrices_performance Performance Considerations
// <hr>
//
// When the Hermitian property of a matrix is known beforehands using the HermitianMatrix adaptor
// instead of a general matrix can be a considerable performance advantage. This is particularly
// true in case the Hermitian matrix is also symmetric (i.e. has built-in element types). The
// \b Blaze library tries to exploit the properties of Hermitian (symmetric) matrices whenever
// possible. However, there are also situations when using a Hermitian matrix introduces some
// overhead. The following examples demonstrate several situations where Hermitian matrices can
// positively or negatively impact performance.
//
// \n \subsection adaptors_hermitian_matrices_matrix_matrix_multiplication Positive Impact: Matrix/Matrix Multiplication
//
// When multiplying two matrices, at least one of which is symmetric, \b Blaze can exploit the fact
// that \f$ A = A^T \f$ and choose the fastest and most suited combination of storage orders for the
// multiplication. The following example demonstrates this by means of a dense matrix/sparse matrix
// multiplication:
\code
using blaze::DynamicMatrix;
using blaze::HermitianMatrix;
using blaze::rowMajor;
using blaze::columnMajor;
HermitianMatrix< DynamicMatrix<double,rowMajor> > A; // Both Hermitian and symmetric
HermitianMatrix< CompressedMatrix<double,columnMajor> > B; // Both Hermitian and symmetric
DynamicMatrix<double,columnMajor> C;
// ... Resizing and initialization
C = A * B;
\endcode
// Intuitively, the chosen combination of a row-major and a column-major matrix is the most suited
// for maximum performance. However, \b Blaze evaluates the multiplication as
\code
C = A * trans( B );
\endcode
// which significantly increases the performance since in contrast to the original formulation the
// optimized form can be vectorized. Therefore, in the context of matrix multiplications, using a
// symmetric matrix is obviously an advantage.
//
// \n \subsection adaptors_hermitian_matrices_matrix_vector_multiplication Positive Impact: Matrix/Vector Multiplication
//
// A similar optimization is possible in case of matrix/vector multiplications:
\code
using blaze::DynamicMatrix;
using blaze::DynamicVector;
using blaze::CompressedVector;
using blaze::HermitianMatrix;
using blaze::rowMajor;
using blaze::columnVector;
HermitianMatrix< DynamicMatrix<double,rowMajor> > A; // Hermitian and symmetric
CompressedVector<double,columnVector> x;
DynamicVector<double,columnVector> y;
// ... Resizing and initialization
y = A * x;
\endcode
// In this example it is not intuitively apparent that using a row-major matrix is not the best
// possible choice in terms of performance since the computation cannot be vectorized. Choosing
// a column-major matrix instead, however, would enable a vectorized computation. Therefore
// \b Blaze exploits the fact that \c A is symmetric, selects the best suited storage order and
// evaluates the multiplication as
\code
y = trans( A ) * x;
\endcode
// which also significantly increases the performance.
//
// \n \subsection adaptors_hermitian_matrices_views Positive Impact: Row/Column Views on Column/Row-Major Matrices
//
// Another example is the optimization of a row view on a column-major symmetric matrix:
\code
using blaze::DynamicMatrix;
using blaze::HermitianMatrix;
using blaze::Row;
using blaze::rowMajor;
using blaze::columnMajor;
typedef HermitianMatrix< DynamicMatrix<double,columnMajor> > DynamicHermitian;
DynamicHermitian A( 10UL ); // Both Hermitian and symmetric
Row<DynamicHermitian> row5 = row( A, 5UL );
\endcode
// Usually, a row view on a column-major matrix results in a considerable performance decrease in
// comparison to a row view on a row-major matrix due to the non-contiguous storage of the matrix
// elements. However, in case of symmetric matrices, \b Blaze instead uses the according column of
// the matrix, which provides the same performance as if the matrix would be row-major. Note that
// this also works for column views on row-major matrices, where \b Blaze can use the according
// row instead of a column in order to provide maximum performance.
//
// \n \subsection adaptors_hermitian_matrices_assignment Negative Impact: Assignment of a General Matrix
//
// In contrast to using a Hermitian matrix on the right-hand side of an assignment (i.e. for read
// access), which introduces absolutely no performance penalty, using a Hermitian matrix on the
// left-hand side of an assignment (i.e. for write access) may introduce additional overhead when
// it is assigned a general matrix, which is not Hermitian at compile time:
\code
using blaze::DynamicMatrix;
using blaze::HermitianMatrix;
HermitianMatrix< DynamicMatrix< complex<double> > > A, C;
DynamicMatrix<double> B;
B = A; // Only read-access to the Hermitian matrix; no performance penalty
C = A; // Assignment of a Hermitian matrix to another Hermitian matrix; no runtime overhead
C = B; // Assignment of a general matrix to a Hermitian matrix; some runtime overhead
\endcode
// When assigning a general, potentially not Hermitian matrix to a Hermitian matrix it is necessary
// to check whether the matrix is Hermitian at runtime in order to guarantee the Hermitian property
// of the Hermitian matrix. In case it turns out to be Hermitian, it is assigned as efficiently as
// possible, if it is not, an exception is thrown. In order to prevent this runtime overhead it is
// therefore generally advisable to assign Hermitian matrices to other Hermitian matrices.\n
// In this context it is especially noteworthy that in contrast to additions and subtractions the
// multiplication of two Hermitian matrices does not necessarily result in another Hermitian matrix:
\code
HermitianMatrix< DynamicMatrix<double> > A, B, C;
C = A + B; // Results in a Hermitian matrix; no runtime overhead
C = A - B; // Results in a Hermitian matrix; no runtime overhead
C = A * B; // Is not guaranteed to result in a Hermitian matrix; some runtime overhead
\endcode

// <hr>
//
// Triangular matrices come in three flavors: Lower triangular matrices provide the compile time
// guarantee to be square matrices and that the upper part of the matrix contains only default
// elements that cannot be modified. Upper triangular matrices on the other hand provide the
// compile time guarantee to be square and that the lower part of the matrix contains only fixed
// default elements. Finally, diagonal matrices provide the compile time guarantee to be square
// and that both the lower and upper part of the matrix contain only immutable default elements.
// These properties can be exploited to gain higher performance and/or to save memory. Within the
// \b Blaze library, several kinds of lower and upper triangular and diagonal matrices are realized
// by the following class templates:
//
// Lower triangular matrices:

//
// In case a resizable matrix is used (as for instance blaze::HybridMatrix, blaze::DynamicMatrix,

// Extending the number of rows and columns by 2, resulting in a 7x7 matrix

// The next example demonstrates the (compound) assignment to rows/columns and submatrices of

\endcode
// \n \subsection adaptors_triangular_matrices_initialization The Elements of a Dense Triangular Matrix are Always Default Initialized!
//
// Although this results in a small loss of efficiency during the creation of a dense lower or
// upper matrix this initialization is important since otherwise the lower/upper matrix property
// of dense lower matrices would not be guaranteed:
\code
using blaze::DynamicMatrix;
using blaze::LowerMatrix;
using blaze::UpperMatrix;
// Uninitialized, 5x5 row-major dynamic matrix
DynamicMatrix<int,rowMajor> A( 5, 5 );
// 5x5 row-major lower dynamic matrix with default initialized upper matrix
LowerMatrix< DynamicMatrix<int,rowMajor> > B( 5 );
// 7x7 column-major upper dynamic matrix with default initialized lower matrix
UpperMatrix< DynamicMatrix<int,columnMajor> > C( 7 );
// 3x3 row-major diagonal dynamic matrix with default initialized lower and upper matrix
DiagonalMatrix< DynamicMatrix<int,rowMajor> > D( 3 );
\endcode
// \n \subsection adaptors_triangular_matrices_storage Dense Triangular Matrices Store All Elements!
//
// All dense triangular matrices store all \f$ N \times N \f$ elements, including the immutable
// elements in the lower or upper part, respectively. Therefore dense triangular matrices don't
// provide any kind of memory reduction! There are two main reasons for this: First, storing also
// the zero elements guarantees maximum performance for many algorithms that perform vectorized
// operations on the triangular matrices, which is especially true for small dense matrices.
// Second, conceptually all triangular adaptors merely restrict the interface to the matrix type
// \c MT and do not change the data layout or the underlying matrix type.
//
// This property matters most for diagonal matrices. In order to achieve the perfect combination
// of performance and memory consumption for a diagonal matrix it is recommended to use dense
// matrices for small diagonal matrices and sparse matrices for large diagonal matrices:
\code
// Recommendation 1: use dense matrices for small diagonal matrices
typedef blaze::DiagonalMatrix< blaze::StaticMatrix<float,3UL,3UL> > SmallDiagonalMatrix;
// Recommendation 2: use sparse matrices for large diagonal matrices
typedef blaze::DiagonalMatrix< blaze::CompressedMatrix<float> > LargeDiagonalMatrix;
\endcode
// \n \subsection adaptors_triangular_matrices_scaling Unitriangular Matrices Cannot Be Scaled!
//
// Since the diagonal elements of a unitriangular matrix have a fixed value of 1 it is not possible
// to self-scale such a matrix:
\code
using blaze::DynamicMatrix;
using blaze::UniLowerMatrix;
UniLowerMatrix< DynamicMatrix<int> > A( 4 );
A *= 2; // Compilation error; Scale operation is not available on an unilower matrix
A /= 2; // Compilation error; Scale operation is not available on an unilower matrix
A.scale( 2 ); // Compilation error; Scale function is not available on an unilower matrix
A = A * 2; // Throws an exception; Invalid assignment of non-unilower matrix
A = A / 2; // Throws an exception; Invalid assignment of non-unilower matrix
\endcode
// \n \section adaptors_triangular_matrices_arithmetic_operations Arithmetic Operations
// <hr>
//
// A lower and upper triangular matrix can participate in numerical operations in any way any other
// dense or sparse matrix can participate. It can also be combined with any other dense or sparse
// vector or matrix. The following code example gives an impression of the use of blaze::LowerMatrix
// and blaze::UpperMatrix within arithmetic operations:
\code
using blaze::LowerMatrix;
using blaze::DynamicMatrix;
using blaze::HybridMatrix;
using blaze::StaticMatrix;
using blaze::CompressedMatrix;
using blaze::rowMajor;
using blaze::columnMajor;
DynamicMatrix<double,rowMajor> A( 3, 3 );
CompressedMatrix<double,rowMajor> B( 3, 3 );
LowerMatrix< DynamicMatrix<double,rowMajor> > C( 3 );
UpperMatrix< CompressedMatrix<double,rowMajor> > D( 3 );
LowerMatrix< HybridMatrix<float,3UL,3UL,rowMajor> > E;
UpperMatrix< StaticMatrix<float,3UL,3UL,columnMajor> > F;
E = A + B; // Matrix addition and assignment to a row-major lower matrix
F = C - D; // Matrix subtraction and assignment to a column-major upper matrix
F = A * D; // Matrix multiplication between a dense and a sparse matrix
C *= 2.0; // In-place scaling of matrix C
E = 2.0 * B; // Scaling of matrix B
F = C * 2.0; // Scaling of matrix C
E += A - B; // Addition assignment
F -= C + D; // Subtraction assignment
F *= A * D; // Multiplication assignment
\endcode
// Note that diagonal, unitriangular and strictly triangular matrix types can be used in the same
// way, but may pose some additional restrictions (see the according class documentations).
//
//
// \n \section adaptors_triangular_matrices_block_matrices Triangular Block Matrices
// <hr>
//
// It is also possible to use triangular block matrices:
\code
using blaze::CompressedMatrix;
using blaze::DynamicMatrix;
using blaze::StaticMatrix;
using blaze::LowerMatrix;
using blaze::UpperMatrix;
// Definition of a 5x5 lower block matrix based on DynamicMatrix
LowerMatrix< DynamicMatrix< StaticMatrix<int,3UL,3UL> > > A( 5 );
// Definition of a 7x7 upper block matrix based on CompressedMatrix
UpperMatrix< CompressedMatrix< StaticMatrix<int,3UL,3UL> > > B( 7 );
\endcode
// Also in this case the triangular matrix invariant is enforced, i.e. it is not possible to
// manipulate elements in the upper part (lower triangular matrix) or the lower part (upper
// triangular matrix) of the matrix:
\code
const StaticMatrix<int,3UL,3UL> C{ { 1, -4, 5 },
{ 6, 8, -3 },
{ 2, -1, 2 } };
A(2,4)(1,1) = -5; // Invalid manipulation of upper matrix element; Results in an exception
B.insert( 4, 2, C ); // Invalid insertion of the elements (4,2); Results in an exception
\endcode
// Note that unitriangular matrices are restricted to numeric element types and therefore cannot
// be used for block matrices:
\code
using blaze::CompressedMatrix;
using blaze::DynamicMatrix;
using blaze::StaticMatrix;
using blaze::UniLowerMatrix;
using blaze::UniUpperMatrix;
// Compilation error: lower unitriangular matrices are restricted to numeric element types
UniLowerMatrix< DynamicMatrix< StaticMatrix<int,3UL,3UL> > > A( 5 );
// Compilation error: upper unitriangular matrices are restricted to numeric element types
UniUpperMatrix< CompressedMatrix< StaticMatrix<int,3UL,3UL> > > B( 7 );
\endcode

//
// \n \section adaptors_triangular_matrices_performance Performance Considerations
// <hr>
//
// The \b Blaze library tries to exploit the properties of lower and upper triangular matrices
// whenever and wherever possible. Therefore using triangular matrices instead of a general
// matrices can result in a considerable performance improvement. However, there are also
// situations when using a triangular matrix introduces some overhead. The following examples
// demonstrate several common situations where triangular matrices can positively or negatively
// impact performance.
//
// \n \subsection adaptors_triangular_matrices_matrix_matrix_multiplication Positive Impact: Matrix/Matrix Multiplication
//
// When multiplying two matrices, at least one of which is triangular, \b Blaze can exploit the
// fact that either the lower or upper part of the matrix contains only default elements and
// restrict the algorithm to the non-zero elements. The following example demonstrates this by
// means of a dense matrix/dense matrix multiplication with lower triangular matrices:
\code
using blaze::DynamicMatrix;
using blaze::LowerMatrix;
using blaze::rowMajor;
using blaze::columnMajor;
LowerMatrix< DynamicMatrix<double,rowMajor> > A;
LowerMatrix< DynamicMatrix<double,columnMajor> > B;
DynamicMatrix<double,columnMajor> C;
// ... Resizing and initialization
C = A * B;
\endcode
// In comparison to a general matrix multiplication, the performance advantage is significant,
// especially for large matrices. Therefore is it highly recommended to use the blaze::LowerMatrix
// and blaze::UpperMatrix adaptors when a matrix is known to be lower or upper triangular,
// respectively. Note however that the performance advantage is most pronounced for dense matrices
// and much less so for sparse matrices.
//
// \n \subsection adaptors_triangular_matrices_matrix_vector_multiplication Positive Impact: Matrix/Vector Multiplication
//
// A similar performance improvement can be gained when using a triangular matrix in a matrix/vector
// multiplication:
\code
using blaze::DynamicMatrix;
using blaze::DynamicVector;
using blaze::rowMajor;
using blaze::columnVector;
LowerMatrix< DynamicMatrix<double,rowMajor> > A;
DynamicVector<double,columnVector> x, y;
// ... Resizing and initialization
y = A * x;
\endcode
// In this example, \b Blaze also exploits the structure of the matrix and approx. halves the
// runtime of the multiplication. Also in case of matrix/vector multiplications the performance
// improvement is most pronounced for dense matrices and much less so for sparse matrices.
//
// \n \subsection adaptors_triangular_matrices_assignment Negative Impact: Assignment of a General Matrix
//
// In contrast to using a triangular matrix on the right-hand side of an assignment (i.e. for
// read access), which introduces absolutely no performance penalty, using a triangular matrix
// on the left-hand side of an assignment (i.e. for write access) may introduce additional
// overhead when it is assigned a general matrix, which is not triangular at compile time:
\code
using blaze::DynamicMatrix;
using blaze::LowerMatrix;
LowerMatrix< DynamicMatrix<double> > A, C;
DynamicMatrix<double> B;
B = A; // Only read-access to the lower matrix; no performance penalty
C = A; // Assignment of a lower matrix to another lower matrix; no runtime overhead
C = B; // Assignment of a general matrix to a lower matrix; some runtime overhead
\endcode
// When assigning a general (potentially not lower triangular) matrix to a lower matrix or a
// general (potentially not upper triangular) matrix to an upper matrix it is necessary to check
// whether the matrix is lower or upper at runtime in order to guarantee the triangular property
// of the matrix. In case it turns out to be lower or upper, respectively, it is assigned as
// efficiently as possible, if it is not, an exception is thrown. In order to prevent this runtime
// overhead it is therefore generally advisable to assign lower or upper triangular matrices to
// other lower or upper triangular matrices.\n
// In this context it is especially noteworthy that the addition, subtraction, and multiplication
// of two triangular matrices of the same structure always results in another triangular matrix:
\code
LowerMatrix< DynamicMatrix<double> > A, B, C;
C = A + B; // Results in a lower matrix; no runtime overhead
C = A - B; // Results in a lower matrix; no runtime overhead
C = A * B; // Results in a lower matrix; no runtime overhead
\endcode
\code
UpperMatrix< DynamicMatrix<double> > A, B, C;
C = A + B; // Results in a upper matrix; no runtime overhead
C = A - B; // Results in a upper matrix; no runtime overhead
C = A * B; // Results in a upper matrix; no runtime overhead
\endcode

// Views represents parts of a vector or matrix, such as a subvector, a submatrix, or a specific

// Views also act as alias to the elements of the vector or matrix: Changes made to the elements

// Subvectors provide views on a specific part of a dense or sparse vector. As such, subvectors
// act as a reference to a specific range within a vector. This reference is valid and can be
// used in every way any other dense or sparse vector can be used as long as the vector containing

// vector are immediately visible in the subvector.
//
//
// \n \section views_subvectors_class The Subvector Class Template
// <hr>
//
// The blaze::Subvector class template represents a view on a specific subvector of a dense or
// sparse vector primitive. It can be included via the header file
\code
#include <blaze/math/Subvector.h>
\endcode
// The type of the vector is specified via two template parameters:
\code
template< typename VT, bool AF >
class Subvector;
\endcode
// - \c VT: specifies the type of the vector primitive. Subvector can be used with every vector
// primitive or view, but does not work with any vector expression type.
// - \c AF: the alignment flag specifies whether the subvector is aligned (blaze::aligned) or
// unaligned (blaze::unaligned). The default value is blaze::unaligned.
//
//
// \n \section views_subvectors_setup Setup of Subvectors
// <hr>
//
// A view on a dense or sparse subvector can be created very conveniently via the \c subvector()
// function. This view can be treated as any other vector, i.e. it can be assigned to, it can
// be copied from, and it can be used in arithmetic operations. A subvector created from a row
// vector can be used as any other row vector, a subvector created from a column vector can be
// used as any other column vector. The view can also be used on both sides of an assignment:
// The subvector can either be used as an alias to grant write access to a specific subvector
// of a vector primitive on the left-hand side of an assignment or to grant read-access to a
// specific subvector of a vector primitive or expression on the right-hand side of an assignment.
// The following example demonstrates this in detail:
\code
typedef blaze::DynamicVector<double,blaze::rowVector> DenseVectorType;
typedef blaze::CompressedVector<int,blaze::rowVector> SparseVectorType;
DenseVectorType d1, d2;
SparseVectorType s1, s2;
// ... Resizing and initialization
// Creating a view on the first ten elements of the dense vector d1
blaze::Subvector<DenseVectorType> dsv = subvector( d1, 0UL, 10UL );
// Creating a view on the second ten elements of the sparse vector s1
blaze::Subvector<SparseVectorType> ssv = subvector( s1, 10UL, 10UL );
// Creating a view on the addition of d2 and s2
dsv = subvector( d2 + s2, 5UL, 10UL );
// Creating a view on the multiplication of d2 and s2
ssv = subvector( d2 * s2, 2UL, 10UL );
\endcode
// The \c subvector() function can be used on any dense or sparse vector, including expressions,
// as demonstrated in the example. Note however that a blaze::Subvector can only be instantiated
// with a dense or sparse vector primitive, i.e. with types that can be written, and not with an
// expression type.
//
//
// \n \section views_subvectors_common_operations Common Operations
// <hr>
//
// A subvector view can be used like any other dense or sparse vector. For instance, the current
// number of elements can be obtained via the \c size() function, the current capacity via the
// \c capacity() function, and the number of non-zero elements via the \c nonZeros() function.
// However, since subvectors are references to a specific range of a vector, several operations
// are not possible on views, such as resizing and swapping. The following example shows this by
// means of a dense subvector view:
\code
typedef blaze::DynamicVector<int,blaze::rowVector> VectorType;
typedef blaze::Subvector<VectorType> SubvectorType;
VectorType v( 42UL );
// ... Resizing and initialization
// Creating a view on the range [5..15] of vector v
SubvectorType sv = subvector( v, 5UL, 10UL );
sv.size(); // Returns the number of elements in the subvector
sv.capacity(); // Returns the capacity of the subvector
sv.nonZeros(); // Returns the number of non-zero elements contained in the subvector
sv.resize( 84UL ); // Compilation error: Cannot resize a subvector of a vector
SubvectorType sv2 = subvector( v, 15UL, 10UL );
swap( sv, sv2 ); // Compilation error: Swap operation not allowed
\endcode
// \n \section views_subvectors_element_access Element Access

B = forEach( A, []( double d ){ return std::sqrt( d ); } );
\endcode
// This example demonstrates the most convenient way of defining a custom operation by passing a

// In order for the functor to work in a call to \c forEach() it must define a function call
// operator, which accepts arguments of the type of the according vector or matrix elements.
//
// Although the operation is automatically parallelized depending on the size of the vector or

//
// All SIMD types provide the \c value data member for a direct access to the underlying intrinsic

double operator()( double a ) const
{
return std::sqrt( a );
}
simd_double_t load( simd_double_t a ) const
{
return _mm256_sqrt_pd( a.value );
}

\endcode
// In this example, whenever vectorization is generally applicable, the \c load() function is
// called instead of the function call operator for as long as the number of remaining elements
// is larger-or-equal to the width of the packed SIMD type. In all other cases (which also
// includes peel-off and remainder loops) the scalar operation is used.
//
// Please note that this example has two drawbacks: First, it will only compile in case the
// intrinsic \c _mm256_sqrt_pd() function is available (i.e. when AVX is active). Second, the
// availability of AVX is not taken into account. The first drawback can be alleviated by making
// the \c load() function a function template. The second drawback can be dealt with by adding a
// \c simdEnabled() function template to the functor:
\code
struct Sqrt
{
double operator()( double a ) const
{
return std::sqrt( a );
}
template< typename T >
T load( T a ) const
{
return _mm256_sqrt_pd( a.value );
}
template< typename T >
static constexpr bool simdEnabled() {
#if defined(__AVX__)
return true;
#else
return false;
#endif
}
};
\endcode
// The \c simdEnabled() function must be a \c static, \c constexpr function and must return whether
// or not vectorization is available for the given data type \c T. In case the function returns
// \c true, the \c load() function is used for a vectorized evaluation, in case the function
// returns \c false, \c load() is not called.
//
// Note that this is a simplified example that is only working when used for dense vectors and
// matrices with double precision floating point elements. The following code shows the complete
// implementation of the according functor that is used within the \b Blaze library. The \b Blaze
// \c Sqrt functor is working for all data types that are providing a square root operation:
\code
namespace blaze {
struct Sqrt

{
return sqrt( a );
}

BLAZE_ALWAYS_INLINE auto load( const T& a ) const
{
BLAZE_CONSTRAINT_MUST_BE_SIMD_TYPE( T );
return sqrt( a );

//
// \n \section openmp_setup OpenMP Setup
// <hr>
//
// To enable the OpenMP-based parallelization, all that needs to be done is to explicitly specify
// the use of OpenMP on the command line:
\code
-fopenmp // GNU C++ compiler
-openmp // Intel C++ compiler
/openmp // Visual Studio
\endcode
// This simple action will cause the \b Blaze library to automatically try to run all operations
// in parallel with the specified number of threads.
//
// As common for OpenMP, the number of threads can be specified either via an environment variable
\code
export OMP_NUM_THREADS=4 // Unix systems
set OMP_NUM_THREADS=4 // Windows systems
\endcode
// or via an explicit call to the \c omp_set_num_threads() function:
\code
omp_set_num_threads( 4 );
\endcode
// Alternatively, the number of threads can also be specified via the \c setNumThreads() function
// provided by the \b Blaze library:
\code
blaze::setNumThreads( 4 );
\endcode
// Please note that the \b Blaze library does not limit the available number of threads. Therefore
// it is in YOUR responsibility to choose an appropriate number of threads. The best performance,
// though, can be expected if the specified number of threads matches the available number of
// cores.
//
// In order to query the number of threads used for the parallelization of operations, the
// \c getNumThreads() function can be used:
\code
const size_t threads = blaze::getNumThreads();
\endcode
// In the context of OpenMP, the function returns the maximum number of threads OpenMP will use
// within a parallel region and is therefore equivalent to the \c omp_get_max_threads() function.
//
//
// \n \section openmp_configuration OpenMP Configuration
// <hr>
//
// Note that \b Blaze is not unconditionally running an operation in parallel. In case \b Blaze
// deems the parallel execution as counterproductive for the overall performance, the operation
// is executed serially. One of the main reasons for not executing an operation in parallel is
// the size of the operands. For instance, a vector addition is only executed in parallel if the
// size of both vector operands exceeds a certain threshold. Otherwise, the performance could
// seriously decrease due to the overhead caused by the thread setup. However, in order to be
// able to adjust the \b Blaze library to a specific system, it is possible to configure these
// thresholds manually. All shared memory thresholds are contained within the configuration file
// <tt>./blaze/config/Thresholds.h</tt>.
//
// Please note that these thresholds are highly sensitiv to the used system architecture and
// the shared memory parallelization technique (see also \ref cpp_threads_parallelization and
// \ref boost_threads_parallelization). Therefore the default values cannot guarantee maximum
// performance for all possible situations and configurations. They merely provide a reasonable
// standard for the current CPU generation.
//
//
// \n \section openmp_first_touch First Touch Policy
// <hr>
//
// So far the \b Blaze library does not (yet) automatically initialize dynamic memory according
// to the first touch principle. Consider for instance the following vector triad example:
\code
using blaze::columnVector;
const size_t N( 1000000UL );
blaze::DynamicVector<double,columnVector> a( N ), b( N ), c( N ), d( N );
// Initialization of the vectors b, c, and d
for( size_t i=0UL; i<N; ++i ) {
b[i] = rand<double>();
c[i] = rand<double>();
d[i] = rand<double>();
}
// Performing a vector triad
a = b + c * d;
\endcode
// If this code, which is prototypical for many OpenMP applications that have not been optimized
// for ccNUMA architectures, is run across several locality domains (LD), it will not scale
// beyond the maximum performance achievable on a single LD if the working set does not fit into
// the cache. This is because the initialization loop is executed by a single thread, writing to
// \c b, \c c, and \c d for the first time. Hence, all memory pages belonging to those arrays will
// be mapped into a single LD.
//
// As mentioned above, this problem can be solved by performing vector initialization in parallel:
\code
// ...
// Initialization of the vectors b, c, and d
#pragma omp parallel for
for( size_t i=0UL; i<N; ++i ) {
b[i] = rand<double>();
c[i] = rand<double>();
d[i] = rand<double>();
}
// ...
\endcode
// This simple modification makes a huge difference on ccNUMA in memory-bound situations (as for
// instance in all BLAS level 1 operations and partially BLAS level 2 operations). Therefore, in
// order to achieve the maximum possible performance, it is imperative to initialize the memory
// according to the later use of the data structures.
//
//
// \n \section openmp_limitations Limitations of the OpenMP Parallelization
// <hr>
//
// There are a few important limitations to the current \b Blaze OpenMP parallelization. The first
// one involves the explicit use of an OpenMP parallel region (see \ref openmp_parallel), the
// other one the OpenMP \c sections directive (see \ref openmp_sections).
//
//
// \n \subsection openmp_parallel The Parallel Directive
//
// In OpenMP threads are explicitly spawned via the an OpenMP parallel directive:
\code
// Serial region, executed by a single thread
#pragma omp parallel
{
// Parallel region, executed by the specified number of threads
}
// Serial region, executed by a single thread
\endcode
// Conceptually, the specified number of threads (see \ref openmp_setup) is created every time a
// parallel directive is encountered. Therefore, from a performance point of view, it seems to be
// beneficial to use a single OpenMP parallel directive for several operations:
\code
blaze::DynamicVector<double> x, y1, y2;
blaze::DynamicMatrix<double> A, B;
#pragma omp parallel
{
y1 = A * x;
y2 = B * x;
}
\endcode
// Unfortunately, this optimization approach is not allowed within the \b Blaze library. More
// explicitly, it is not allowed to put an operation into a parallel region. The reason is that
// the entire code contained within a parallel region is executed by all threads. Although this
// appears to just comprise the contained computations, a computation (or more specifically the
// assignment of an expression to a vector or matrix) can contain additional logic that must not
// be handled by multiple threads (as for instance memory allocations, setup of temporaries, etc.).
// Therefore it is not possible to manually start a parallel region for several operations, but
// \b Blaze will spawn threads automatically, depending on the specifics of the operation at hand
// and the given operands.
//
// \n \subsection openmp_sections The Sections Directive
//
// OpenMP provides several work-sharing construct to distribute work among threads. One of these
// constructs is the \c sections directive:
\code
blaze::DynamicVector<double> x, y1, y2;
blaze::DynamicMatrix<double> A, B;
// ... Resizing and initialization
#pragma omp sections
{
#pragma omp section
y1 = A * x;
#pragma omp section
y2 = B * x;
}
\endcode
// In this example, two threads are used to compute two distinct matrix/vector multiplications
// concurrently. Thereby each of the \c sections is executed by exactly one thread.
//
// Unfortunately \b Blaze does not support concurrent parallel computations and therefore this
// approach does not work with any of the \b Blaze parallelization techniques. All techniques
// (including the C++11 and Boost thread parallelizations; see \ref cpp_threads_parallelization
// and \ref boost_threads_parallelization) are optimized for the parallel computation of an
// operation within a single thread of execution. This means that \b Blaze tries to use all
// available threads to compute the result of a single operation as efficiently as possible.
// Therefore, for this special case, it is advisable to disable all \b Blaze parallelizations
// and to let \b Blaze compute all operations within a \c sections directive in serial. This can
// be done by either completely disabling the \b Blaze parallelization (see \ref serial_execution)
// or by selectively serializing all operations within a \c sections directive via the \c serial()
// function:
\code
blaze::DynamicVector<double> x, y1, y2;
blaze::DynamicMatrix<double> A, B;
// ... Resizing and initialization
#pragma omp sections
{
#pragma omp section
y1 = serial( A * x );
#pragma omp section
y2 = serial( B * x );
}
\endcode
// Please note that the use of the \c BLAZE_SERIAL_SECTION (see also \ref serial_execution) does
// NOT work in this context!

// As in case of the OpenMP-based parallelization \b Blaze is not unconditionally running an
// operation in parallel. In case \b Blaze deems the parallel execution as counterproductive for
// the overall performance, the operation is executed serially. One of the main reasons for not
// executing an operation in parallel is the size of the operands. For instance, a vector addition
// is only executed in parallel if the size of both vector operands exceeds a certain threshold.
// Otherwise, the performance could seriously decrease due to the overhead caused by the thread
// setup. However, in order to be able to adjust the \b Blaze library to a specific system, it
// is possible to configure these thresholds manually. All thresholds are contained within the
// configuration file <tt>./blaze/config/Thresholds.h</tt>.
//
// Please note that these thresholds are highly sensitiv to the used system architecture and
// the shared memory parallelization technique. Therefore the default values cannot guarantee
// maximum performance for all possible situations and configurations. They merely provide a
// reasonable standard for the current CPU generation. Also note that the provided defaults
// have been determined using the OpenMP parallelization and require individual adaption for
// the C++11 thread parallelization.

// Unfortunately, the C++11 parallelization of the \b Blaze library is affected from this bug.

// ... Using the C++11 thread parallelization of Blaze
shutDownThreads();

\f[ A = P \cdot L \cdot U, \f]\n

// diagonal elements of \c L are not stored. In case \a A is a row-major matrix the result is

// - \f$ A^T*x=b \f$ if \a A is row-major

//**Configuration Files****************************************************************************
/*!\page configuration_files Configuration Files
//
// \tableofcontents
//
//
// Sometimes it might necessary to adapt \b Blaze to specific requirements. For this purpose
// \b Blaze provides several configuration files in the <tt>./blaze/config/</tt> subdirectory,
// which provide ample opportunity to customize internal settings, behavior, and thresholds.
// This chapter explains the most important of these configuration files.
//
//
// \n \section transpose_flag Default Vector Storage
// <hr>
//
// The \b Blaze default is that all vectors are created as column vectors (if not specified
// explicitly):
\code
blaze::StaticVector<double,3UL> x; // Creates a 3-dimensional static column vector
\endcode
// The header file <tt>./blaze/config/TransposeFlag.h</tt> allows the configuration of the default
// vector storage (i.e. the default transpose flag of the vectors). Via the \c defaultTransposeFlag
// value the default transpose flag for all vector of the \b Blaze library can be specified:
\code
constexpr bool defaultTransposeFlag = columnVector;
\endcode
// Valid settings for the \c defaultTransposeFlag are blaze::rowVector and blaze::columnVector.
//
//
// \n \section storage_order Default Matrix Storage
// <hr>
//
// Matrices are by default created as row-major matrices:
\code
blaze::StaticMatrix<double,3UL,3UL> A; // Creates a 3x3 row-major matrix
\endcode
// The header file <tt>./blaze/config/StorageOrder.h</tt> allows the configuration of the default
// matrix storage order. Via the \c defaultStorageOrder value the default storage order for all
// matrices of the \b Blaze library can be specified.
\code
constexpr bool defaultStorageOrder = rowMajor;
\endcode
// Valid settings for the \c defaultStorageOrder are blaze::rowMajor and blaze::columnMajor.
//
//
// \n \section blas_mode BLAS Mode
// <hr>
//
// In order to achieve maximum performance for multiplications with dense matrices, \b Blaze can
// be configured to use a BLAS library. Via the following compilation switch in the configuration
// file <tt>./blaze/config/BLAS.h</tt> BLAS can be enabled:
\code
#define BLAZE_BLAS_MODE 1
\endcode
// In case the selected BLAS library provides parallel execution, the \c BLAZE_BLAS_IS_PARALLEL
// switch should be activated to prevent \b Blaze from parallelizing on its own:
\code
#define BLAZE_BLAS_IS_PARALLEL 1
\endcode
// In case no BLAS library is available, \b Blaze will still work and will not be reduced in
// functionality, but performance may be limited.
//
//
// \n \section cache_size Cache Size
// <hr>
//
// The optimization of several \b Blaze compute kernels depends on the cache size of the target
// architecture. By default, \b Blaze assumes a cache size of 3 MiByte. However, for optimal
// speed the exact cache size of the system should be provided via the \c cacheSize value in the
// <tt>./blaze/config/CacheSize.h</tt> configuration file:
\code
constexpr size_t cacheSize = 3145728UL;
\endcode
// \n \section vectorization Vectorization
// <hr>
//
// In order to achieve maximum performance and to exploit the compute power of a target platform
// the \b Blaze library attempts to vectorize all linear algebra operations by SSE, AVX, and/or
// MIC intrinsics, depending on which instruction set is available. However, it is possible to
// disable the vectorization entirely by the compile time switch in the configuration file
// <tt>./blaze/config/Vectorization.h</tt>:
\code
#define BLAZE_USE_VECTORIZATION 1
\endcode
// In case the switch is set to 1, vectorization is enabled and the \b Blaze library is allowed
// to use intrinsics to speed up computations. In case the switch is set to 0, vectorization is
// disabled entirely and the \b Blaze library chooses default, non-vectorized functionality for
// the operations. Note that deactivating the vectorization may pose a severe performance
// limitation for a large number of operations!
//
//
// \n \section thresholds Thresholds
// <hr>
//
// For many computations \b Blaze distinguishes between small and large vectors and matrices.
// This separation is especially important for the parallel execution of computations, since
// the use of several threads only pays off for sufficiently large vectors and matrices.
// Additionally, it also enables \b Blaze to select kernels that are optimized for a specific
// size.
//
// In order to distinguish between small and large data structures \b Blaze provides several
// thresholds that can be adapted to the characteristics of the target platform. For instance,
// the \c DMATDVECMULT_THRESHOLD specifies the threshold between the application of the custom
// \b Blaze kernels for small dense matrix/dense vector multiplications and the BLAS kernels
// for large multiplications. All thresholds, including the thresholds for the OpenMP- and
// thread-based parallelization, are contained within the configuration file
// <tt>./blaze/config/Thresholds.h</tt>.
//
//
// \n \section padding Padding
// <hr>
//
// By default the \b Blaze library uses padding for all dense vectors and matrices in order to
// achieve maximum performance in all operations. Due to padding, the proper alignment of data
// elements can be guaranteed and the need for remainder loops is minimized. However, on the
// downside padding introduces an additional memory overhead, which can be large depending on
// the used data type.
//
// The configuration file <tt>./blaze/config/Optimizations.h</tt> provides a compile time switch
// that can be used to (de-)activate padding:
\code
constexpr bool usePadding = true;
\endcode
// If \c usePadding is set to \c true padding is enabled for all dense vectors and matrices, if
// it is set to \c false padding is disabled. Note however that disabling padding can considerably
// reduce the performance of all dense vector and matrix operations!
//
//
// \n \section streaming Streaming (Non-Temporal Stores)
// <hr>
//
// For vectors and matrices that don't fit into the cache anymore non-temporal stores can provide
// a significant performance advantage of about 20%. However, this advantage is only in effect in
// case the memory bandwidth of the target architecture is maxed out. If the target architecture's
// memory bandwidth cannot be exhausted the use of non-temporal stores can decrease performance
// instead of increasing it.
//
// The configuration file <tt>./blaze/config/Optimizations.h</tt> provides a compile time switch
// that can be used to (de-)activate streaming:
\code
constexpr bool useStreaming = true;
\endcode
// If \c useStreaming is set to \c true streaming is enabled, if it is set to \c false streaming
// is disabled. It is recommended to consult the target architecture's white papers to decide
// whether streaming is beneficial or hurtful for performance.

// \n \section block_vectors_and_matrices_general General Concepts
// <hr>
//
// In addition to fundamental element types, the \b Blaze library supports vectors and matrices
// with non-fundamental element type. For instance, it is possible to define block matrices by
// using a matrix type as the element type:
\code
using blaze::DynamicMatrix;
using blaze::DynamicVector;
using blaze::rowMajor;
using blaze::columnVector;
DynamicMatrix< DynamicMatrix<double,rowMajor>, rowMajor > A;
DynamicVector< DynamicVector<double,columnVector >, columnVector > x, y;
// ... Resizing and initialization
y = A * x;
\endcode
// The matrix/vector multiplication in this example runs fully parallel and uses vectorization
// for every inner matrix/vector multiplication and vector addition.
//
//
// \n \section block_vectors_and_matrices_pitfalls Pitfalls
// <hr>
//
// The only thing to keep in mind when using non-fundamental element types is that all operations
// between the elements have to be well defined. More specifically, the size of vector and matrix
// elements has to match. The attempt to combine two non-matching elements results in either a
// compilation error (in case of statically sized elements) or an exception (for dynamically sized
// elements):
\code
DynamicVector< StaticVector<int,2UL> > a;
DynamicVector< StaticVector<int,3UL> > b;
DynamicVector< DynamicVector<int> > c( a + b ); // Compilation error: element size doesn't match
\endcode
// Therefore please don't forget that dynamically sized elements (e.g. \c blaze::DynamicVector,
// \c blaze::HybridVector, \c blaze::DynamicMatrix, \c blaze::HybridMatrix, ...) need to be sized
// accordingly upfront.
//
//
// \n \section block_vectors_and_matrices_example Example
// <hr>
//
// The following example demonstrates a complete multiplication between a statically sized block
// matrix and block vector:
\code
// ( ( 1 1 ) ( 2 2 ) ) ( ( 1 ) ) ( ( 10 ) )

//**Custom Data Types******************************************************************************
/*!\page custom_data_types Custom Data Types
//
//
// The \b Blaze library tries hard to make the use of custom data types as convenient, easy and
// intuitive as possible. However, unfortunately it is not possible to meet the requirements of
// all possible data types. Thus it might be necessary to provide \b Blaze with some additional
// information about the data type. The following sections give an overview of the necessary steps
// to enable the use of the hypothetical custom data type \c custom::double_t for vector and
// matrix operations. For example:
\code
blaze::DynamicVector<custom::double_t> a, b, c;
// ... Resizing and initialization
c = a + b;
\endcode
// The \b Blaze library assumes that the \c custom::double_t data type provides \c operator+()
// for additions, \c operator-() for subtractions, \c operator*() for multiplications and
// \c operator/() for divisions. If any of these functions is missing it is necessary to implement
// the operator to perform the according operation. For this example we assume that the custom
// data type provides the four following functions instead of operators:
\code
namespace custom {
double_t add ( const double_t& a, const double_t b );
double_t sub ( const double_t& a, const double_t b );
double_t mult( const double_t& a, const double_t b );
double_t div ( const double_t& a, const double_t b );
} // namespace custom
\endcode
// The following implementations will satisfy the requirements of the \b Blaze library:
\code
inline custom::double_t operator+( const custom::double_t& a, const custom::double_t& b )
{
return add( a, b );
}
inline custom::double_t operator-( const custom::double_t& a, const custom::double_t& b )
{
return sub( a, b );
}
inline custom::double_t operator*( const custom::double_t& a, const custom::double_t& b )
{
return mult( a, b );
}
inline custom::double_t operator/( const custom::double_t& a, const custom::double_t& b )
{
return div( a, b );
}
\endcode
// \b Blaze will use all the information provided with these functions (for instance the return
// type) to properly handle the operations. In the rare case that the return type cannot be
// automatically determined from the operator it might be additionally necessary to provide a
// specialization of the following four \b Blaze class templates:
\code
namespace blaze {
template<>
struct AddTrait<custom::double_t,custom::double_t> {
typedef custom::double_t Type;
};
template<>
struct SubTrait<custom::double_t,custom::double_t> {
typedef custom::double_t Type;
};
template<>
struct MultTrait<custom::double_t,custom::double_t> {
typedef custom::double_t Type;
};
template<>
struct DivTrait<custom::double_t,custom::double_t> {
typedef custom::double_t Type;
};
} // namespace blaze
\endcode
// The same steps are necessary if several custom data types need to be combined (as for instance
// \c custom::double_t and \c custom::float_t). Note that in this case both permutations need to
// be taken into account:
\code
custom::double_t operator+( const custom::double_t& a, const custom::float_t& b );
custom::double_t operator+( const custom::float_t& a, const custom::double_t& b );
// ...
\endcode
// Please note that only built-in data types apply for vectorization and thus custom data types
// cannot achieve maximum performance!

//**Customization of the Error Reporting Mechanism*************************************************
/*!\page error_reporting_customization Customization of the Error Reporting Mechanism
//
// \tableofcontents
//
//
// \n \section error_reporting_background Background
// <hr>
//
// The default way of \b Blaze to report errors of any kind is to throw a standard exception.
// However, although in general this approach works well, in certain environments and under
// special circumstances exceptions may not be the mechanism of choice and a different error
// reporting mechanism may be desirable. For this reason, \b Blaze provides several macros,
// which enable the customization of the error reporting mechanism. Via these macros it is
// possible to replace the standard exceptions by some other exception type or a completely
// different approach to report errors.
//
//
// \n \section error_reporting_general_customization Customization of the Reporting Mechanism
// <hr>
//
// In some cases it might be necessary to adapt the entire error reporting mechanism and to
// replace it by some other means to signal failure. The primary macro for this purpose is the
// \c BLAZE_THROW macro:
\code
#define BLAZE_THROW( EXCEPTION ) \
throw EXCEPTION
\endcode
// This macro represents the default mechanism of the \b Blaze library to report errors of any
// kind. In order to customize the error reporing mechanism all that needs to be done is to
// define the macro prior to including any \b Blaze header file. This will cause the \b Blaze
// specific mechanism to be overridden. The following example demonstrates this by replacing
// exceptions by a call to a \c log() function and a direct call to abort:
\code
#define BLAZE_THROW( EXCEPTION ) \
log( "..." ); \
abort()
#include <blaze/Blaze.h>
\endcode
// Doing this will trigger a call to \c log() and an abort instead of throwing an exception
// whenever an error (such as an invalid argument) is detected.
//
// \note It is possible to execute several statements instead of executing a single statement to
// throw an exception. Also note that it is recommended to define the macro such that a subsequent
// semicolon is required!
//
// \warning This macro is provided with the intention to assist in adapting \b Blaze to special
// conditions and environments. However, the customization of the error reporting mechanism via
// this macro can have a significant effect on the library. Thus be advised to use the macro
// with due care!
//
//
// \n \section error_reporting_exception_customization Customization of the Type of Exceptions
// <hr>
//
// In addition to the customization of the entire error reporting mechanism it is also possible
// to customize the type of exceptions being thrown. This can be achieved by customizing any
// number of the following macros:
\code
#define BLAZE_THROW_BAD_ALLOC \
BLAZE_THROW( std::bad_alloc() )
#define BLAZE_THROW_LOGIC_ERROR( MESSAGE ) \
BLAZE_THROW( std::logic_error( MESSAGE ) )
#define BLAZE_THROW_INVALID_ARGUMENT( MESSAGE ) \
BLAZE_THROW( std::invalid_argument( MESSAGE ) )
#define BLAZE_THROW_LENGTH_ERROR( MESSAGE ) \
BLAZE_THROW( std::length_error( MESSAGE ) )
#define BLAZE_THROW_OUT_OF_RANGE( MESSAGE ) \
BLAZE_THROW( std::out_of_range( MESSAGE ) )
#define BLAZE_THROW_RUNTIME_ERROR( MESSAGE ) \
BLAZE_THROW( std::runtime_error( MESSAGE ) )
\endcode
// In order to customize the type of exception the according macro has to be defined prior to
// including any \b Blaze header file. This will override the \b Blaze default behavior. The
// following example demonstrates this by replacing \c std::invalid_argument by a custom
// exception type:
\code
class InvalidArgument
{
public:
InvalidArgument();
explicit InvalidArgument( const std::string& message );
// ...
};
#define BLAZE_THROW_INVALID_ARGUMENT( MESSAGE ) \
BLAZE_THROW( InvalidArgument( MESSAGE ) )
#include <blaze/Blaze.h>
\endcode
// By manually defining the macro, an \c InvalidArgument exception is thrown instead of a
// \c std::invalid_argument exception. Note that it is recommended to define the macro such
// that a subsequent semicolon is required!
//
// \warning These macros are provided with the intention to assist in adapting \b Blaze to
// special conditions and environments. However, the customization of the type of an exception
// via this macro may have an effect on the library. Thus be advised to use the macro with due
// care!
//
//
// \n \section error_reporting_special_errors Customization of Special Errors
// <hr>
//
// Last but not least it is possible to customize the error reporting for special kinds of errors.
// This can be achieved by customizing any number of the following macros:
\code
#define BLAZE_THROW_DIVISION_BY_ZERO( MESSAGE ) \
BLAZE_THROW_RUNTIME_ERROR( MESSAGE )
#define BLAZE_THROW_LAPACK_ERROR( MESSAGE ) \
BLAZE_THROW_RUNTIME_ERROR( MESSAGE )
\endcode
// As explained in the previous sections, in order to customize the handling of special errors
// the according macro has to be defined prior to including any \b Blaze header file. This will
// override the \b Blaze default behavior.

//*************************************************************************************************
//**Intra-Statement Optimization*******************************************************************
/*!\page intra_statement_optimization Intra-Statement Optimization
//
// One of the prime features of the \b Blaze library is the automatic intra-statement optimization.
// In order to optimize the overall performance of every single statement \b Blaze attempts to
// rearrange the operands based on their types. For instance, the following addition of dense and
// sparse vectors
\code
blaze::DynamicVector<double> d1, d2, d3;
blaze::CompressedVector<double> s1;
// ... Resizing and initialization
d3 = d1 + s1 + d2;
\endcode
// is automatically rearranged and evaluated as
\code
// ...
d3 = d1 + d2 + s1; // <- Note that s1 and d2 have been rearranged
\endcode
// This order of operands is highly favorable for the overall performance since the addition of
// the two dense vectors \c d1 and \c d2 can be handled much more efficiently in a vectorized
// fashion.
//
// This intra-statement optimization can have a tremendous effect on the performance of a statement.
// Consider for instance the following computation:
\code
blaze::DynamicMatrix<double> A, B;
blaze::DynamicVector<double> x, y;
// ... Resizing and initialization
y = A * B * x;
\endcode
// Since multiplications are evaluated from left to right, this statement would result in a
// matrix/matrix multiplication, followed by a matrix/vector multiplication. However, if the
// right subexpression is evaluated first, the performance can be dramatically improved since the
// matrix/matrix multiplication can be avoided in favor of a second matrix/vector multiplication.
// The \b Blaze library exploits this by automatically restructuring the expression such that the
// right multiplication is evaluated first:
\code
// ...
y = A * ( B * x );
\endcode
// Note however that although this intra-statement optimization may result in a measurable or
// even significant performance improvement, this behavior may be undesirable for several reasons,
// for instance because of numerical stability. Therefore, in case the order of evaluation matters,
// the best solution is to be explicit and to separate a statement into several statements:
\code
blaze::DynamicVector<double> d1, d2, d3;
blaze::CompressedVector<double> s1;
// ... Resizing and initialization
d3 = d1 + s1; // Compute the dense vector/sparse vector addition first ...
d3 += d2; // ... and afterwards add the second dense vector
\endcode
\code
// ...
blaze::DynamicMatrix<double> A, B, C;
blaze::DynamicVector<double> x, y;
// ... Resizing and initialization
C = A * B; // Compute the left-hand side matrix-matrix multiplication first ...
y = C * x; // ... before the right-hand side matrix-vector multiplication
\endcode
// Alternatively, it is also possible to use the \c eval() function to fix the order of evaluation:
\code
blaze::DynamicVector<double> d1, d2, d3;
blaze::CompressedVector<double> s1;
// ... Resizing and initialization
d3 = d1 + eval( s1 + d2 );
\endcode
\code
blaze::DynamicMatrix<double> A, B;
blaze::DynamicVector<double> x, y;
// ... Resizing and initialization
y = eval( A * B ) * x;
\endcode

@defgroup ATOMIC_OPS Atomic Operations
These functions are used for implementing the many different varieties of atomic operations.
The compiler is at liberty to inline atomic operations that are naturally supported
by the target architecture. For instance on IA-32 architecture an atomic like this can be inlined
@code
static int s = 0;
#pragma omp atomic
s++;
@endcode
using the single instruction: `lock; incl s`
However the runtime does provide entrypoints for these operations to support compilers that choose
not to inline them. (For instance, `__kmpc_atomic_fixed4_add` could be used to perform the
increment above.)
The names of the functions are encoded by using the data type name and the operation name, as in these tables.
Data Type | Data type encoding

int8_t | `fixed1`
uint8_t | `fixed1u`
int16_t | `fixed2`

For non-commutative operations, `_rev` can also be added for the reversed operation.
For the functions that capture the result, the suffix `_cpt` is added.
Update Functions
================
The general form of an atomic function that just performs an update (without a `capture`)
@code
void __kmpc_atomic_<datatype>_<operation>( ident_t *id_ref, int gtid, TYPE * lhs, TYPE rhs );
@endcode
@param ident_t a pointer to source location
@param gtid the global thread id
@param lhs a pointer to the left operand
@param rhs the right operand
`capture` functions
===================
The capture functions perform an atomic update and return a result, which is either the value
before the capture, or that after. They take an additional argument to determine which result is returned.
Their general form is therefore
@code
TYPE __kmpc_atomic_<datatype>_<operation>_cpt( ident_t *id_ref, int gtid, TYPE * lhs, TYPE rhs, int flag );
@endcode
@param ident_t a pointer to source location
@param gtid the global thread id
@param lhs a pointer to the left operand
@param rhs the right operand
@param flag one if the result is to be captured *after* the operation, zero if captured *before*.
The one set of exceptions to this is the `complex<float>` type where the value is not returned,
rather an extra argument pointer is passed.
They look like
@code
void __kmpc_atomic_cmplx4_<op>_cpt( ident_t *id_ref, int gtid, kmp_cmplx32 * lhs, kmp_cmplx32 rhs, kmp_cmplx32 * out, int flag );
@endcode
Read and Write Operations
=========================
The OpenMP<sup>*</sup> standard now supports atomic operations that simply ensure that the
value is read or written atomically, with no modification
performed. In many cases on IA-32 architecture these operations can be inlined since
the architecture guarantees that no tearing occurs on aligned objects
accessed with a single memory operation of up to 64 bits in size.
The general form of the read operations is
@code
TYPE __kmpc_atomic_<type>_rd ( ident_t *id_ref, int gtid, TYPE * loc );
@endcode
For the write operations the form is
@code
void __kmpc_atomic_<type>_wr ( ident_t *id_ref, int gtid, TYPE * lhs, TYPE rhs );
@endcode
Full list of functions
======================
This leads to the generation of 376 atomic functions, as follows.
Functons for integers
---------------------
There are versions here for integers of size 1,2,4 and 8 bytes both signed and unsigned (where that matters).

Functions for Complex types
---------------------------
Functions for complex types whose component floating point variables are of size 4,8,10 or 16 bytes.
The names here are based on the size of the component float, *not* the size of the complex type. So
`__kmpc_atomc_cmplx8_add` is an operation on a `complex<double>` or `complex(kind=8)`, *not* `complex<float>`.

// For GNU compatibility, we may need to use a critical section,
// even though it is not required by the ISA.
//
// On IA-32 architecture, all atomic operations except for fixed 4 byte add,
// sub, and bitwise logical ops, and 1 & 2 byte logical ops use a common
// critical section. On Intel(R) 64, all atomic operations are done with fetch
// and add or compare and exchange. Therefore, the FLAG parameter to this
// macro is either KMP_ARCH_X86 or 0 (or 1, for Intel-specific extension which
// require a critical section, where we predict that they will be implemented
// in the Gnu codegen by calling GOMP_atomic_start() / GOMP_atomic_end()).
//
// When the OP_GOMP_CRITICAL macro is used in a *CRITICAL* macro construct,
// the FLAG parameter should always be 1. If we know that we will be using
// a critical section, then we want to make certain that we use the generic
// lock __kmp_atomic_lock to protect the atomic update, and not of of the
// locks that are specialized based upon the size or type of the data.
//
// If FLAG is 0, then we are relying on dead code elimination by the build
// compiler to get rid of the useless block of code, and save a needless
// branch at runtime.

//**Configuration and Installation*****************************************************************
/*!\page configuration_and_installation Configuration and Installation
//
// Since \b Blaze is a header-only library, setting up the \b Blaze library on a particular system
// is a fairly easy two step process. In the following, this two step process is explained in
// detail, preceded only by a short summary of the requirements.
//
//
// \n \section requirements Requirements
// <hr>
//
// In order for \b Blaze to work properly, the Boost library must be installed on the system. It
// is recommended to use the newest Boost library available, but \b Blaze requires at minimum the
// Boost version 1.54.0. If you don't have Boost installed on your system, you can download it for
// free from 'http://www.boost.org'.
//
// Additionally, for maximum performance \b Blaze expects you to have a BLAS library installed
// (<a href="http://software.intel.com/en-us/articles/intel-mkl/">Intel MKL</a>,
// <a href="http://developer.amd.com/libraries/acml/">ACML</a>,
// <a href="http://math-atlas.sourceforge.net">Atlas</a>,
// <a href="http://www.tacc.utexas.edu/tacc-projects/gotoblas2">Goto</a>, ...). If you don't
// have a BLAS library installed on your system, \b Blaze will still work and will not be reduced
// in functionality, but performance may be limited. Thus it is strongly recommended to install a
// BLAS library.
//
// Furthermore, for computing the determinant of a dense matrix and for the dense matrix inversion
// \b Blaze requires <a href="https://en.wikipedia.org/wiki/LAPACK">LAPACK</a>. When either of
// these features is used it is necessary to link the LAPACK library to the final executable. If
// no LAPACK library is available the use of these features will result in a linker error.
//
//
// \n \section step_1_installation Step 1: Installation
// <hr>
//
// \subsection step_1_installation_unix Linux/MacOSX User
//
// The first step is the installation of the header files. Since \b Blaze only consists of header
// files, the <tt>./blaze</tt> subdirectory can be simply copied to a standard include directory
// (note that this requires root privileges):
\code
cp -r ./blaze /usr/local/include
\endcode
// Alternatively, on Unix-based machines (which includes Linux and Mac OS X) the
// \c CPLUS_INCLUDE_PATH environment variable can be set. The specified directory will be
// searched after any directories specified on the command line with the option \c -I and
// before the standard default directories (such as \c /usr/local/include and \c /usr/include).
// Assuming a user named 'Jon', the environment variable can be set as follows:
\code
CPLUS_INCLUDE_PATH=/usr/home/jon/blaze
export CPLUS_INCLUDE_PATH
\endcode
// Last but not least, the <tt>./blaze</tt> subdirectory can be explicitly specified on the
// command line. The following example demonstrates this by means of the GNU C++ compiler:
\code
g++ -I/usr/home/jon/blaze -o BlazeTest BlazeTest.cpp
\endcode
// \n \subsection step_1_installation_windows Windows User
//
// Windows doesn't have a standard include directory. Therefore the \b Blaze header files can be
// copied to any other directory or simply left in the default \b Blaze directory. However, the
// chosen include directory has to be explicitly specified as include path. In Visual Studio,
// this is done via the project property pages, configuration properties, C/C++, General settings.
// Here the additional include directories can be specified.
//
//
// \n \section step_2_configuration Step 2: Configuration
// <hr>
//
// The second step is the configuration and customization of the \b Blaze library. Many aspects of
// \b Blaze can be adapted to specific requirements, environments and architectures by customizing
// the header files in the <tt>./blaze/config/</tt> subdirectory. Since the default settings are
// reasonable for most systems this step can also be skipped. However, in order to achieve maximum
// performance a customization of at least the following configuration files is required:
//
// - <b><tt>./blaze/config/BLAS.h</tt></b>: Via this configuration file \b Blaze can be enabled
// to use a third-party BLAS library for several basic linear algebra functions (such as for
// instance dense matrix multiplications). In case no BLAS library is used, all linear algebra
// functions use the default implementations of the \b Blaze library and therefore BLAS is not a
// requirement for the compilation process. However, please note that performance may be limited.
// - <b><tt>./blaze/config/CacheSize.h</tt></b>: This file contains the hardware specific cache
// settings. \b Blaze uses this information to optimize its cache usage. For maximum performance
// it is recommended to adapt these setting to a specific target architecture.
// - <b><tt>./blaze/config/Thresholds.h</tt></b>: This file contains all thresholds for the
// customization of the \b Blaze compute kernels. In order to tune the kernels for a specific
// architecture and to maximize performance it can be necessary to adjust the thresholds,
// especially for a parallel execution (see \ref shared_memory_parallelization).
//
// For an overview of other customization options and more details, please see the section
// \ref configuration_files.

//*************************************************************************************************
//**Getting Started********************************************************************************
/*!\page getting_started Getting Started
//
// This short tutorial serves the purpose to give a quick overview of the way mathematical
// expressions have to be formulated in \b Blaze. Starting with \ref vector_types, the following
// long tutorial covers the most important aspects of the \b Blaze math library.
//
//
// \n \section getting_started_vector_example A First Example
//
// \b Blaze is written such that using mathematical expressions is as close to mathematical
// textbooks as possible and therefore as intuitive as possible. In nearly all cases the seemingly
// easiest solution is the right solution and most users experience no problems when trying to
// use \b Blaze in the most natural way. The following example gives a first impression of the
// formulation of a vector addition in \b Blaze:
\code
#include <iostream>
#include <blaze/Math.h>
using blaze::StaticVector;
using blaze::DynamicVector;
// Instantiation of a static 3D column vector. The vector is directly initialized as
// ( 4 -2 5 )
StaticVector<int,3UL> a{ 4, -2, 5 };
// Instantiation of a dynamic 3D column vector. Via the subscript operator the values are set to
// ( 2 5 -3 )
DynamicVector<int> b( 3UL );
b[0] = 2;
b[1] = 5;
b[2] = -3;
// Adding the vectors a and b
DynamicVector<int> c = a + b;
// Printing the result of the vector addition
std::cout << "c =\n" << c << "\n";
\endcode
// Note that the entire \b Blaze math library can be included via the \c blaze/Math.h header
// file. Alternatively, the entire \b Blaze library, including both the math and the entire
// utility module, can be included via the \c blaze/Blaze.h header file. Also note that all
// classes and functions of \b Blaze are contained in the blaze namespace.\n\n
//
// Assuming that this program resides in a source file called \c FirstExample.cpp, it can be
// compiled for instance via the GNU C++ compiler:
\code
g++ -ansi -O3 -DNDEBUG -mavx -o FirstExample FirstExample.cpp
\endcode
// Note the definition of the \c NDEBUG preprocessor symbol. In order to achieve maximum
// performance, it is necessary to compile the program in release mode, which deactivates
// all debugging functionality inside \b Blaze. It is also strongly recommended to specify
// the available architecture specific instruction set (as for instance the AVX instruction
// set, which if available can be activated via the \c -mavx flag). This allows \b Blaze
// to optimize computations via vectorization.\n\n
//
// When running the resulting executable \c FirstExample, the output of the last line of
// this small program is
\code
c =
6
3
2
\endcode
// \n \section getting_started_matrix_example An Example Involving Matrices
//
// Similarly easy and intuitive are expressions involving matrices:
\code
#include <blaze/Math.h>
using namespace blaze;
// Instantiating a dynamic 3D column vector
DynamicVector<int> x{ 4, -1, 3 };
// Instantiating a dynamic 2x3 row-major matrix, preinitialized with 0. Via the function call
// operator three values of the matrix are explicitly set to get the matrix
// ( 1 0 4 )
// ( 0 -2 0 )
DynamicMatrix<int> A( 2UL, 3UL, 0 );
A(0,0) = 1;
A(0,2) = 4;
A(1,1) = -2;
// Performing a matrix/vector multiplication
DynamicVector<int> y = A * x;
// Printing the resulting vector
std::cout << "y =\n" << y << "\n";
// Instantiating a static column-major matrix. The matrix is directly initialized as
// ( 3 -1 )
// ( 0 2 )
// ( -1 0 )
StaticMatrix<int,3UL,2UL,columnMajor> B{ { 3, -1 }, { 0, 2 }, { -1, 0 } };
// Performing a matrix/matrix multiplication
DynamicMatrix<int> C = A * B;
// Printing the resulting matrix
std::cout << "C =\n" << C << "\n";
\endcode
// The output of this program is
\code
y =
16
2
C =
( -1 -1 )
( 0 4 )
\endcode
// \n \section getting_started_complex_example A Complex Example
//
// The following example is much more sophisticated. It shows the implementation of the Conjugate
// Gradient (CG) algorithm (http://en.wikipedia.org/wiki/Conjugate_gradient) by means of the
// \b Blaze library:
//
// \image html cg.jpg
//
// In this example it is not important to understand the CG algorithm itself, but to see the
// advantage of the API of the \b Blaze library. In the \b Blaze implementation we will use a
// sparse matrix/dense vector multiplication for a 2D Poisson equation using \f$ N \times N \f$
// unknowns. It becomes apparent that the core of the algorithm is very close to the mathematical
// formulation and therefore has huge advantages in terms of readability and maintainability,
// while the performance of the code is close to the expected theoretical peak performance:
\code
const size_t NN( N*N );
blaze::CompressedMatrix<double,rowMajor> A( NN, NN );
blaze::DynamicVector<double,columnVector> x( NN, 1.0 ), b( NN, 0.0 ), r( NN ), p( NN ), Ap( NN );
double alpha, beta, delta;
// ... Initializing the sparse matrix A
// Performing the CG algorithm
r = b - A * x;
p = r;
delta = (r,r);
for( size_t iteration=0UL; iteration<iterations; ++iteration )
{
Ap = A * p;
alpha = delta / (p,Ap);
x += alpha * p;
r -= alpha * Ap;
beta = (r,r);
if( std::sqrt( beta ) < 1E-8 ) break;
p = r + ( beta / delta ) * p;
delta = beta;
}
\endcode
// \n Hopefully this short tutorial gives a good first impression of how mathematical expressions
// are formulated with \b Blaze. The following long tutorial, starting with \ref vector_types,
// will cover all aspects of the \b Blaze math library, i.e. it will introduce all vector and
// matrix types, all possible operations on vectors and matrices, and of course all possible
// mathematical expressions.

// <hr>
//
// The blaze::CustomVector class template provides the functionality to represent an external
// array of elements of arbitrary type and a fixed size as a native \b Blaze dense vector data
// structure. Thus in contrast to all other dense vector types a custom vector does not perform
// any kind of memory allocation by itself, but it is provided with an existing array of element
// during construction. A custom vector can therefore be considered an alias to the existing
// array. It can be included via the header file
\code
#include <blaze/math/CustomVector.h>
\endcode
// The type of the elements, the properties of the given array of elements and the transpose
// flag of the vector can be specified via the following four template parameters:
\code
template< typename Type, bool AF, bool PF, bool TF >
class CustomVector;
\endcode
// - Type: specifies the type of the vector elements. blaze::CustomVector can be used with
// any non-cv-qualified, non-reference, non-pointer element type.
// - AF : specifies whether the represented, external arrays are properly aligned with
// respect to the available instruction set (SSE, AVX, ...) or not.
// - PF : specified whether the represented, external arrays are properly padded with
// respect to the available instruction set (SSE, AVX, ...) or not.
// - TF : specifies whether the vector is a row vector (\c blaze::rowVector) or a column
// vector (\c blaze::columnVector). The default value is \c blaze::columnVector.
//
// The blaze::CustomVector is the right choice if any external array needs to be represented as
// a \b Blaze dense vector data structure or if a custom memory allocation strategy needs to be
// realized:
\code
using blaze::CustomVector;
using blaze::aligned;
using blaze::unaligned;
using blaze::padded;
using blaze::unpadded;
// Definition of an unmanaged custom column vector for unaligned, unpadded integer arrays
typedef CustomVector<int,unaligned,unpadded,columnVector> UnalignedUnpadded;
std::vector<int> vec( 7UL );
UnalignedUnpadded a( &vec[0], 7UL );
// Definition of a managed custom column vector for unaligned but padded 'float' arrays
typedef CustomVector<float,unaligned,padded,columnVector> UnalignedPadded;
UnalignedPadded b( new float[16], 9UL, 16UL, blaze::ArrayDelete() );
// Definition of a managed custom row vector for aligned, unpadded 'double' arrays
typedef CustomVector<double,aligned,unpadded,rowVector> AlignedUnpadded;
AlignedUnpadded c( blaze::allocate<double>( 7UL ), 7UL, blaze::Deallocate() );
// Definition of a managed custom row vector for aligned, padded 'complex<double>' arrays
typedef CustomVector<complex<double>,aligned,padded,columnVector> AlignedPadded;
AlignedPadded d( allocate< complex<double> >( 8UL ), 5UL, 8UL, blaze::Deallocate() );
\endcode
// In comparison with the remaining \b Blaze dense vector types blaze::CustomVector has several
// special characteristics. All of these result from the fact that a custom vector is not
// performing any kind of memory allocation, but instead is given an existing array of elements.
// The following sections discuss all of these characteristics:
//
// -# <b>\ref vector_types_custom_vector_memory_management</b>
// -# <b>\ref vector_types_custom_vector_copy_operations</b>
// -# <b>\ref vector_types_custom_vector_alignment</b>
// -# <b>\ref vector_types_custom_vector_padding</b>
//
// \n \subsection vector_types_custom_vector_memory_management Memory Management
//
// The blaze::CustomVector class template acts as an adaptor for an existing array of elements. As
// such it provides everything that is required to use the array just like a native \b Blaze dense
// vector data structure. However, this flexibility comes with the price that the user of a custom
// vector is responsible for the resource management.
//
// When constructing a custom vector there are two choices: Either a user manually manages the
// array of elements outside the custom vector, or alternatively passes the responsibility for
// the memory management to an instance of CustomVector. In the second case the CustomVector
// class employs shared ownership between all copies of the custom vector, which reference the
// same array.
//
// The following examples give an impression of several possible types of custom vectors:
\code
using blaze::CustomVector;
using blaze::ArrayDelete;
using blaze::Deallocate;
using blaze::allocate;
using blaze::aligned;
using blaze::unaligned;
using blaze::padded;
using blaze::unpadded;
using blaze::columnVector;
using blaze::rowVector;
// Definition of a 3-dimensional custom vector with unaligned, unpadded and externally
// managed integer array. Note that the std::vector must be guaranteed to outlive the
// custom vector!
std::vector<int> vec( 3UL );
CustomVector<int,unaligned,unpadded> a( &vec[0], 3UL );
// Definition of a custom row vector with size 3 for unaligned, unpadded integer arrays.
// The responsibility for the memory management is passed to the custom vector by
// providing a deleter of type 'blaze::ArrayDelete' that is used during the destruction
// of the custom vector.
CustomVector<int,unaligned,unpadded,rowVector> b( new int[3], 3UL, ArrayDelete() );
// Definition of a custom vector with size 3 and capacity 16 with aligned and padded
// integer array. The memory management is passed to the custom vector by providing a
// deleter of type 'blaze::Deallocate'.
CustomVector<int,aligned,padded> c( allocate<int>( 16UL ), 3UL, 16UL, Deallocate() );
\endcode
// It is possible to pass any type of deleter to the constructor. The deleter is only required
// to provide a function call operator that can be passed the pointer to the managed array. As
// an example the following code snipped shows the implementation of two native \b Blaze deleters
// blaze::ArrayDelete and blaze::Deallocate:
\code
namespace blaze {
struct ArrayDelete
{
template< typename Type >
inline void operator()( Type ptr ) const { boost::checked_array_delete( ptr ); }
};
struct Deallocate
{
template< typename Type >
inline void operator()( Type ptr ) const { deallocate( ptr ); }
};
} // namespace blaze
\endcode
// \n \subsection vector_types_custom_vector_copy_operations Copy Operations
//
// As with all dense vectors it is possible to copy construct a custom vector:
\code
using blaze::CustomVector;
using blaze::unaligned;
using blaze::unpadded;
typedef CustomVector<int,unaligned,unpadded> CustomType;
std::vector<int> vec( 5UL, 10 ); // Vector of 5 integers of the value 10
CustomType a( &vec[0], 5UL ); // Represent the std::vector as Blaze dense vector
a[1] = 20; // Also modifies the std::vector
CustomType b( a ); // Creating a copy of vector a
b[2] = 20; // Also affect vector a and the std::vector
\endcode
// It is important to note that a custom vector acts as a reference to the specified array. Thus
// the result of the copy constructor is a new custom vector that is referencing and representing
// the same array as the original custom vector. In case a deleter has been provided to the first
// custom vector, both vectors share the responsibility to destroy the array when the last vector
// goes out of scope.
//
// In contrast to copy construction, just as with references, copy assignment does not change
// which array is referenced by the custom vector, but modifies the values of the array:
\code
std::vector<int> vec2( 5UL, 4 ); // Vector of 5 integers of the value 4
CustomType c( &vec2[0], 5UL ); // Represent the std::vector as Blaze dense vector
a = c; // Copy assignment: Set all values of vector a and b to 4.
\endcode
// \n \subsection vector_types_custom_vector_alignment Alignment
//
// In case the custom vector is specified as \c aligned the passed array must be guaranteed to
// be aligned according to the requirements of the used instruction set (SSE, AVX, ...). For
// instance, if AVX is active an array of integers must be 32-bit aligned:
\code
using blaze::CustomVector;
using blaze::Deallocate;
using blaze::aligned;
using blaze::unpadded;
int* array = blaze::allocate<int>( 5UL ); // Needs to be 32-bit aligned
CustomVector<int,aligned,unpadded> a( array, 5UL, Deallocate() );
\endcode
// In case the alignment requirements are violated, a \c std::invalid_argument exception is
// thrown.
//
// \n \subsection vector_types_custom_vector_padding Padding
//
// Adding padding elements to the end of an array can have a significant impact on the performance.
// For instance, assuming that AVX is available, then two aligned, padded, 3-dimensional vectors
// of double precision values can be added via a single SIMD addition operation:
\code
using blaze::CustomVector;
using blaze::Deallocate;
using blaze::allocate;
using blaze::aligned;
using blaze::padded;
typedef CustomVector<double,aligned,padded> CustomType;
// Creating padded custom vectors of size 3 and a capacity of 4
CustomType a( allocate<double>( 4UL ), 3UL, 4UL, Deallocate() );
CustomType b( allocate<double>( 4UL ), 3UL, 4UL, Deallocate() );
CustomType c( allocate<double>( 4UL ), 3UL, 4UL, Deallocate() );
// ... Initialization
c = a + b; // AVX-based vector addition
\endcode
// In this example, maximum performance is possible. However, in case no padding elements are
// inserted, a scalar addition has to be used:
\code
using blaze::CustomVector;
using blaze::Deallocate;
using blaze::allocate;
using blaze::aligned;
using blaze::unpadded;
typedef CustomVector<double,aligned,unpadded> CustomType;
// Creating unpadded custom vector of size 3
CustomType a( allocate<double>( 3UL ), 3UL, Deallocate() );
CustomType b( allocate<double>( 3UL ), 3UL, Deallocate() );
CustomType c( allocate<double>( 3UL ), 3UL, Deallocate() );
// ... Initialization
c = a + b; // Scalar vector addition
\endcode
// Note the different number of constructor parameters for unpadded and padded custom vectors:
// In contrast to unpadded vectors, where during the construction only the size of the array
// has to be specified, during the construction of a padded custom vector it is additionally
// necessary to explicitly specify the capacity of the array.
//
// The number of padding elements is required to be sufficient with respect to the available
// instruction set: In case of an aligned padded custom vector the added padding elements must
// guarantee that the capacity is a multiple of the SIMD vector width. In case of unaligned
// padded vectors \f$ N-1 \f$ additional padding elements are required, where \f$ N \f$ is
// the SIMD vector width. In case the padding is insufficient with respect to the available
// instruction set, a \c std::invalid_argument exception is thrown.
//
// Please also note that \b Blaze will zero initialize the padding elements in order to achieve
// maximum performance!
//
//
// \n \section vector_types_compressed_vector CompressedVector
// <hr>

//
// Instantiating and setting up a vector is very easy and intuitive. However, there are a few
// rules to take care of:
// - In case the last template parameter (the transpose flag) is omitted, the vector is per
// default a column vector.
// - The elements of a \c StaticVector or \c HybridVector are default initialized (i.e. built-in
// data types are initialized to 0, class types are initialized via the default constructor).
// - Newly allocated elements of a \c DynamicVector or \c CompressedVector remain uninitialized
// if they are of built-in type and are default constructed if they are of class type.
//
// \n \subsection vector_operations_default_construction Default Construction
\code
using blaze::StaticVector;
using blaze::DynamicVector;
using blaze::CompressedVector;
// All vectors can be default constructed. Whereas the size
// of StaticVectors is fixed via the second template parameter,
// the initial size of a default constructed DynamicVector or
// CompressedVector is 0.
StaticVector<int,2UL> v1; // Instantiation of a 2D integer column vector.
// All elements are initialized to 0.
StaticVector<long,3UL,columnVector> v2; // Instantiation of a 3D long integer column vector.
// Again, all elements are initialized to 0L.
DynamicVector<float> v3; // Instantiation of a dynamic single precision column
// vector of size 0.
DynamicVector<double,rowVector> v4; // Instantiation of a dynamic double precision row
// vector of size 0.
CompressedVector<int> v5; // Instantiation of a compressed integer column
// vector of size 0.
CompressedVector<double,rowVector> v6; // Instantiation of a compressed double precision row
// vector of size 0.
\endcode
// \n \subsection vector_operations_size_construction Construction with Specific Size
//
// The \c DynamicVector, \c HybridVector and \c CompressedVector classes offer a constructor that
// allows to immediately give the vector the required size. Whereas both dense vectors (i.e.
// \c DynamicVector and \c HybridVector) use this information to allocate memory for all vector
// elements, \c CompressedVector merely acquires the size but remains empty.
\code
DynamicVector<int,columnVector> v7( 9UL ); // Instantiation of an integer dynamic column vector
// of size 9. The elements are NOT initialized!
HybridVector< complex<float>, 5UL > v8( 2UL ); // Instantiation of a column vector with two single
// precision complex values. The elements are
// default constructed.
CompressedVector<int,rowVector> v9( 10UL ); // Instantiation of a compressed row vector with
// size 10. Initially, the vector provides no
// capacity for non-zero elements.
\endcode
// \n \subsection vector_operations_initialization_constructors Initialization Constructors
//
// All dense vector classes offer a constructor that allows for a direct, homogeneous initialization
// of all vector elements. In contrast, for sparse vectors the predicted number of non-zero elements
// can be specified
\code
StaticVector<int,3UL,rowVector> v10( 2 ); // Instantiation of a 3D integer row vector.
// All elements are initialized to 2.
DynamicVector<float> v11( 3UL, 7.0F ); // Instantiation of a dynamic single precision
// column vector of size 3. All elements are
// set to 7.0F.
CompressedVector<float,rowVector> v12( 15UL, 3UL ); // Instantiation of a single precision column
// vector of size 15, which provides enough
// space for at least 3 non-zero elements.
\endcode
// \n \subsection vector_operations_array_construction Array Construction
//
// Alternatively, all dense vector classes offer a constructor for an initialization with a dynamic
// or static array. If the vector is initialized from a dynamic array, the constructor expects the
// actual size of the array as first argument, the array as second argument. In case of a static
// array, the fixed size of the array is used:
\code
const unique_ptr<double[]> array1( new double[2] );
// ... Initialization of the dynamic array
blaze::StaticVector<double,2UL> v13( 2UL, array1.get() );
int array2[4] = { 4, -5, -6, 7 };
blaze::StaticVector<int,4UL> v14( array2 );
\endcode
// \n \subsection vector_operations_initializer_list_construction Initializer List Construction
//
// In addition, all dense vector classes can be directly initialized by means of an initializer
// list:
\code
blaze::DynamicVector<float> v15{ 1.0F, 2.0F, 3.0F, 4.0F };
\endcode
// \n \subsection vector_operations_copy_construction Copy Construction
//
// All dense and sparse vectors can be created as the copy of any other dense or sparse vector
// with the same transpose flag (i.e. blaze::rowVector or blaze::columnVector).
\code
StaticVector<int,9UL,columnVector> v16( v7 ); // Instantiation of the dense column vector v16
// as copy of the dense column vector v7.
DynamicVector<int,rowVector> v17( v9 ); // Instantiation of the dense row vector v17 as
// copy of the sparse row vector v9.
CompressedVector<int,columnVector> v18( v1 ); // Instantiation of the sparse column vector v18
// as copy of the dense column vector v1.
CompressedVector<float,rowVector> v19( v12 ); // Instantiation of the sparse row vector v19 as
// copy of the row vector v12.
\endcode
// Note that it is not possible to create a \c StaticVector as a copy of a vector with a different
// size:
\code
StaticVector<int,5UL,columnVector> v23( v7 ); // Runtime error: Size does not match!
StaticVector<int,4UL,rowVector> v24( v10 ); // Compile time error: Size does not match!
\endcode
// \n \section vector_operations_assignment Assignment
// <hr>
//
// There are several types of assignment to dense and sparse vectors:
// \ref vector_operations_homogeneous_assignment, \ref vector_operations_array_assignment,
// \ref vector_operations_copy_assignment, and \ref vector_operations_compound_assignment.
//
// \n \subsection vector_operations_homogeneous_assignment Homogeneous Assignment
//
// Sometimes it may be necessary to assign the same value to all elements of a dense vector.
// For this purpose, the assignment operator can be used:
\code
blaze::StaticVector<int,3UL> v1;
blaze::DynamicVector<double> v2;
// Setting all integer elements of the StaticVector to 2
v1 = 2;
// Setting all double precision elements of the DynamicVector to 5.0
v2 = 5.0;
\endcode
// \n \subsection vector_operations_array_assignment Array Assignment
//
// Dense vectors can also be assigned a static array:
\code
blaze::StaticVector<float,2UL> v1;
blaze::DynamicVector<double,rowVector> v2;
float array1[2] = { 1.0F, 2.0F };
double array2[5] = { 2.1, 4.0, -1.7, 8.6, -7.2 };
v1 = array1;
v2 = array2;
\endcode
// \n \subsection vector_operations_initializer_list_assignment Initializer List Assignment
//
// Alternatively, it is possible to directly assign an initializer list to a dense vector:
\code
blaze::StaticVector<float,2UL> v1;
blaze::DynamicVector<double,rowVector> v2;
v1 = { 1.0F, 2.0F };
v2 = { 2.1, 4.0, -1.7, 8.6, -7.2 };
\endcode
// \n \subsection vector_operations_copy_assignment Copy Assignment
//
// For all vector types it is generally possible to assign another vector with the same transpose
// flag (i.e. blaze::columnVector or blaze::rowVector). Note that in case of \c StaticVectors, the
// assigned vector is required to have the same size as the \c StaticVector since the size of a
// \c StaticVector cannot be adapted!
\code
blaze::StaticVector<int,3UL,columnVector> v1;
blaze::DynamicVector<int,columnVector> v2( 3UL );
blaze::DynamicVector<float,columnVector> v3( 5UL );
blaze::CompressedVector<int,columnVector> v4( 3UL );
blaze::CompressedVector<float,rowVector> v5( 3UL );
// ... Initialization of the vectors
v1 = v2; // OK: Assignment of a 3D dense column vector to another 3D dense column vector
v1 = v4; // OK: Assignment of a 3D sparse column vector to a 3D dense column vector
v1 = v3; // Runtime error: Cannot assign a 5D vector to a 3D static vector
v1 = v5; // Compilation error: Cannot assign a row vector to a column vector
\endcode
// \n \subsection vector_operations_compound_assignment Compound Assignment
//
// Next to plain assignment, it is also possible to use addition assignment, subtraction
// assignment, and multiplication assignment. Note however, that in contrast to plain assignment
// the size and the transpose flag of the vectors has be to equal in order to able to perform a
// compound assignment.
\code
blaze::StaticVector<int,5UL,columnVector> v1;
blaze::DynamicVector<int,columnVector> v2( 5UL );
blaze::CompressedVector<float,columnVector> v3( 7UL );
blaze::DynamicVector<float,rowVector> v4( 7UL );
blaze::CompressedVector<float,rowVector> v5( 7UL );
// ... Initialization of the vectors
v1 += v2; // OK: Addition assignment between two column vectors of the same size
v1 += v3; // Runtime error: No compound assignment between vectors of different size
v1 -= v4; // Compilation error: No compound assignment between vectors of different transpose flag
v4 *= v5; // OK: Multiplication assignment between two row vectors of the same size
\endcode
// \n \section vector_operations_element_access Element Access
// <hr>
//
// The easiest and most intuitive way to access a dense or sparse vector is via the subscript
// operator. The indices to access a vector are zero-based:
\code
blaze::DynamicVector<int> v1( 5UL );
v1[0] = 1;
v1[1] = 3;
// ...
blaze::CompressedVector<float> v2( 5UL );
v2[2] = 7.3F;
v2[4] = -1.4F;
\endcode
// Whereas using the subscript operator on a dense vector only accesses the already existing
// element, accessing an element of a sparse vector via the subscript operator potentially
// inserts the element into the vector and may therefore be more expensive. Consider the
// following example:
\code
blaze::CompressedVector<int> v1( 10UL );
for( size_t i=0UL; i<v1.size(); ++i ) {
... = v1[i];
}
\endcode
// Although the compressed vector is only used for read access within the for loop, using the
// subscript operator temporarily inserts 10 non-zero elements into the vector. Therefore, all
// vectors (sparse as well as dense) offer an alternate way via the \c begin(), \c cbegin(),
// \c end(), and \c cend() functions to traverse the currently contained elements by iterators.
// In case of non-const vectors, \c begin() and \c end() return an \c Iterator, which allows a
// manipulation of the non-zero value, in case of a constant vector or in case \c cbegin() or
// \c cend() are used a \c ConstIterator is returned:
\code
using blaze::CompressedVector;
CompressedVector<int> v1( 10UL );
// ... Initialization of the vector
// Traversing the vector by Iterator
for( CompressedVector<int>::Iterator it=v1.begin(); it!=v1.end(); ++it ) {
it->value() = ...; // OK: Write access to the value of the non-zero element.
... = it->value(); // OK: Read access to the value of the non-zero element.
it->index() = ...; // Compilation error: The index of a non-zero element cannot be changed.
... = it->index(); // OK: Read access to the index of the non-zero element.
}
// Traversing the vector by ConstIterator
for( CompressedVector<int>::ConstIterator it=v1.cbegin(); it!=v1.cend(); ++it ) {
it->value() = ...; // Compilation error: Assignment to the value via a ConstIterator is invalid.
... = it->value(); // OK: Read access to the value of the non-zero element.
it->index() = ...; // Compilation error: The index of a non-zero element cannot be changed.
... = it->index(); // OK: Read access to the index of the non-zero element.
}
\endcode
// Note that \c begin(), \c cbegin(), \c end(), and \c cend() are also available as free functions:
\code
for( CompressedVector<int>::Iterator it=begin( v1 ); it!=end( v1 ); ++it ) {
// ...
}
for( CompressedVector<int>::ConstIterator it=cbegin( v1 ); it!=cend( v1 ); ++it ) {
// ...
}
\endcode
// \n \section vector_operations_element_insertion Element Insertion
// <hr>
//
// In contrast to dense vectors, that store all elements independent of their value and that
// offer direct access to all elements, spares vectors only store the non-zero elements contained
// in the vector. Therefore it is necessary to explicitly add elements to the vector. The first
// option to add elements to a sparse vector is the subscript operator:
\code
using blaze::CompressedVector;
CompressedVector<int> v1( 3UL );
v1[1] = 2;
\endcode
// In case the element at the given index is not yet contained in the vector, it is automatically
// inserted. Otherwise the old value is replaced by the new value 2. The operator returns a
// reference to the sparse vector element.\n
// An alternative is the \c set() function: In case the element is not yet contained in the vector
// the element is inserted, else the element's value is modified:
\code
// Insert or modify the value at index 3
v1.set( 3, 1 );
\endcode
// However, insertion of elements can be better controlled via the \c insert() function. In contrast
// to the subscript operator and the \c set() function it emits an exception in case the element is
// already contained in the vector. In order to check for this case, the \c find() function can be
// used:
\code
// In case the element at index 4 is not yet contained in the matrix it is inserted
// with a value of 6.
if( v1.find( 4 ) == v1.end() )
v1.insert( 4, 6 );
\endcode
// Although the \c insert() function is very flexible, due to performance reasons it is not suited
// for the setup of large sparse vectors. A very efficient, yet also very low-level way to fill
// a sparse vector is the \c append() function. It requires the sparse vector to provide enough
// capacity to insert a new element. Additionally, the index of the new element must be larger
// than the index of the previous element. Violating these conditions results in undefined
// behavior!
\code
v1.reserve( 10 ); // Reserving space for 10 non-zero elements
v1.append( 5, -2 ); // Appending the element -2 at index 5
v1.append( 6, 4 ); // Appending the element 4 at index 6
// ...
\endcode
// \n \section vector_operations_member_functions Member Functions
// <hr>
//
// \subsection vector_operations_size .size()
//
// Via the \c size() member function, the current size of a dense or sparse vector can be queried:
\code
// Instantiating a dynamic vector with size 10
blaze::DynamicVector<int> v1( 10UL );
v1.size(); // Returns 10
// Instantiating a compressed vector with size 12 and capacity for 3 non-zero elements
blaze::CompressedVector<double> v2( 12UL, 3UL );
v2.size(); // Returns 12
\endcode
// Alternatively, the free function \c size() can be used to query to current size of a vector.
// In contrast to the member function, the free function can also be used to query the size of
// vector expressions:
\code
size( v1 ); // Returns 10, i.e. has the same effect as the member function
size( v2 ); // Returns 12, i.e. has the same effect as the member function
blaze::DynamicMatrix<int> A( 15UL, 12UL );
size( A * v2 ); // Returns 15, i.e. the size of the resulting vector
\endcode
// \n \subsection vector_operations_capacity .capacity()
//
// Via the \c capacity() (member) function the internal capacity of a dense or sparse vector
// can be queried. Note that the capacity of a vector doesn't have to be equal to the size
// of a vector. In case of a dense vector the capacity will always be greater or equal than
// the size of the vector, in case of a sparse vector the capacity may even be less than
// the size.
\code
v1.capacity(); // Returns at least 10
\endcode
// For symmetry reasons, there is also a free function /c capacity() available that can be used
// to query the capacity:
\code
capacity( v1 ); // Returns at least 10, i.e. has the same effect as the member function
\endcode
// Note, however, that it is not possible to query the capacity of a vector expression:
\code
capacity( A * v1 ); // Compilation error!
\endcode
// \n \subsection vector_operations_nonzeros .nonZeros()
//
// For both dense and sparse vectors the number of non-zero elements can be determined via the
// \c nonZeros() member function. Sparse vectors directly return their number of non-zero
// elements, dense vectors traverse their elements and count the number of non-zero elements.
\code
v1.nonZeros(); // Returns the number of non-zero elements in the dense vector
v2.nonZeros(); // Returns the number of non-zero elements in the sparse vector
\endcode
// There is also a free function \c nonZeros() available to query the current number of non-zero
// elements:
\code
nonZeros( v1 ); // Returns the number of non-zero elements in the dense vector
nonZeros( v2 ); // Returns the number of non-zero elements in the sparse vector
\endcode
// The free \c nonZeros() function can also be used to query the number of non-zero elements in
// a vector expression. However, the result is not the exact number of non-zero elements, but
// may be a rough estimation:
\code
nonZeros( A * v1 ); // Estimates the number of non-zero elements in the vector expression
\endcode
// \n \subsection vector_operations_resize_reserve .resize() / .reserve()
//
// The size of a \c StaticVector is fixed by the second template parameter and a \c CustomVector
// cannot be resized. In contrast, the size of \c DynamicVectors, \c HybridVectors as well as
// \c CompressedVectors can be changed via the \c resize() function:
\code
using blaze::DynamicVector;
using blaze::CompressedVector;
DynamicVector<int,columnVector> v1;
CompressedVector<int,rowVector> v2( 4 );
v2[1] = -2;
v2[3] = 11;
// Adapting the size of the dynamic and compressed vectors. The (optional) second parameter
// specifies whether the existing elements should be preserved. Per default, the existing
// elements are not preserved.
v1.resize( 5UL ); // Resizing vector v1 to 5 elements. Elements of built-in type remain
// uninitialized, elements of class type are default constructed.
v1.resize( 3UL, false ); // Resizing vector v1 to 3 elements. The old elements are lost, the
// new elements are NOT initialized!
v2.resize( 8UL, true ); // Resizing vector v2 to 8 elements. The old elements are preserved.
v2.resize( 5UL, false ); // Resizing vector v2 to 5 elements. The old elements are lost.
\endcode
// Note that resizing a vector invalidates all existing views (see e.g. \ref views_subvectors)
// on the vector:
\code
typedef blaze::DynamicVector<int,rowVector> VectorType;
typedef blaze::Subvector<VectorType> SubvectorType;
VectorType v1( 10UL ); // Creating a dynamic vector of size 10
SubvectorType sv = subvector( v1, 2UL, 5UL ); // Creating a view on the range [2..6]
v1.resize( 6UL ); // Resizing the vector invalidates the view
\endcode
// When the internal capacity of a vector is no longer sufficient, the allocation of a larger
// junk of memory is triggered. In order to avoid frequent reallocations, the \c reserve()
// function can be used up front to set the internal capacity:
\code
blaze::DynamicVector<int> v1;
v1.reserve( 100 );
v1.size(); // Returns 0
v1.capacity(); // Returns at least 100
\endcode
// Note that the size of the vector remains unchanged, but only the internal capacity is set
// according to the specified value!
//
//
// \n \section vector_operations_free_functions Free Functions
// <hr>
//
// \subsection vector_operations_reset_clear reset() / clear()
//
// In order to reset all elements of a vector, the \c reset() function can be used:
\code
// Setup of a single precision column vector, whose elements are initialized with 2.0F.
blaze::DynamicVector<float> v1( 3UL, 2.0F );
// Resetting all elements to 0.0F. Only the elements are reset, the size of the vector is unchanged.
reset( v1 ); // Resetting all elements
v1.size(); // Returns 3: size and capacity remain unchanged
\endcode
// In order to return a vector to its default state (i.e. the state of a default constructed
// vector), the \c clear() function can be used:
\code
// Setup of a single precision column vector, whose elements are initialized with -1.0F.
blaze::DynamicVector<float> v1( 5, -1.0F );
// Resetting the entire vector.
clear( v1 ); // Resetting the entire vector
v1.size(); // Returns 0: size is reset, but capacity remains unchanged
\endcode
// Note that resetting or clearing both dense and sparse vectors does not change the capacity
// of the vectors.
//
//
// \n \subsection vector_operations_isnan isnan()
//
// The \c isnan() function provides the means to check a dense or sparse vector for non-a-number
// elements:
\code
blaze::DynamicVector<double> a;
// ... Resizing and initialization
if( isnan( a ) ) { ... }
\endcode
\code
blaze::CompressedVector<double> a;
// ... Resizing and initialization
if( isnan( a ) ) { ... }
\endcode
// If at least one element of the vector is not-a-number, the function returns \c true, otherwise
// it returns \c false. Please note that this function only works for vectors with floating point
// elements. The attempt to use it for a vector with a non-floating point element type results in
// a compile time error.
//
//
// \n \subsection vector_operations_isdefault isDefault()
//
// The \c isDefault() function returns whether the given dense or sparse vector is in default state:
\code
blaze::HybridVector<int,20UL> a;
// ... Resizing and initialization
if( isDefault( a ) ) { ... }
\endcode
// A vector is in default state if it appears to just have been default constructed. All resizable
// vectors (\c HybridVector, \c DynamicVector, or \c CompressedVector) and \c CustomVector are
// in default state if its size is equal to zero. A non-resizable vector (\c StaticVector, all
// subvectors, rows, and columns) is in default state if all its elements are in default state.
// For instance, in case the vector is instantiated for a built-in integral or floating point data
// type, the function returns \c true in case all vector elements are 0 and \c false in case any
// vector element is not 0.
//
//
// \n \subsection vector_operations_isUniform isUniform()
//
// In order to check if all vector elements are identical, the \c isUniform function can be used:
\code
blaze::DynamicVector<int> a;
// ... Resizing and initialization
if( isUniform( a ) ) { ... }
\endcode
// Note that in case of sparse vectors also the zero elements are also taken into account!
//
//
// \n \subsection vector_operations_min_max min() / max()
//
// The \c min() and the \c max() functions return the smallest and largest element of the given
// dense or sparse vector, respectively:
\code
blaze::StaticVector<int,4UL,rowVector> a{ -5, 2, 7, 4 };
blaze::StaticVector<int,4UL,rowVector> b{ -5, 2, -7, -4 };
min( a ); // Returns -5
min( b ); // Returns -7
max( a ); // Returns 7
max( b ); // Returns 2
\endcode
// In case the vector currently has a size of 0, both functions return 0. Additionally, in case
// a given sparse vector is not completely filled, the zero elements are taken into account. For
// example: the following compressed vector has only 2 non-zero elements. However, the minimum
// of this vector is 0:
\code
blaze::CompressedVector<int> c( 4UL, 2UL );
c[0] = 1;
c[2] = 3;
min( c ); // Returns 0
\endcode
// Also note that the \c min() and \c max() functions can be used to compute the smallest and
// largest element of a vector expression:
\code
min( a + b + c ); // Returns -9, i.e. the smallest value of the resulting vector
max( a - b - c ); // Returns 11, i.e. the largest value of the resulting vector
\endcode
// \n \subsection vector_operators_abs abs()
//
// The \c abs() function can be used to compute the absolute values of each element of a vector.
// For instance, the following computation
\code
blaze::StaticVector<int,3UL,rowVector> a{ -1, 2, -3 };
blaze::StaticVector<int,3UL,rowVector> b( abs( a ) );
\endcode
// results in the vector
\f$ b = \left(\begin{array}{*{1}{c}}
1 \\
2 \\
3 \\
\end{array}\right)\f$
// \n \subsection vector_operators_floor_ceil floor() / ceil()
//
// The \c floor() and \c ceil() functions can be used to round down/up each element of a vector,
// respectively:
\code
blaze::StaticVector<double,3UL,rowVector> a, b;
b = floor( a ); // Rounding down each element of the vector
b = ceil( a ); // Rounding up each element of the vector
\endcode
// \n \subsection vector_operators_conj conj()
//
// The \c conj() function can be applied on a dense or sparse vector to compute the complex
// conjugate of each element of the vector:
\code
using blaze::StaticVector;
typedef std::complex<double> cplx;
// Creating the vector
// ( (-2,-1) )
// ( ( 1, 1) )
StaticVector<cplx,2UL> a{ cplx(-2.0,-1.0), cplx(1.0,1.0) };
// Computing the vector of complex conjugates
// ( (-2, 1) )
// ( ( 1,-1) )
StaticVector<cplx,2UL> b;
b = conj( a );
\endcode
// Additionally, vectors can be conjugated in-place via the \c conjugate() function:
\code
blaze::DynamicVector<cplx> c( 5UL );
conjugate( c ); // In-place conjugate operation.
c = conj( c ); // Same as above
\endcode
// \n \subsection vector_operators_real real()
//
// The \c real() function can be used on a dense or sparse vector to extract the real part of

using blaze::StaticVector;
typedef std::complex<double> cplx;
// Creating the vector
// ( (-2,-1) )
// ( ( 1, 1) )
StaticVector<cplx,2UL> a{ cplx(-2.0,-1.0), cplx(1.0,1.0) };
// Extracting the real part of each vector element
// ( -2 )
// ( 1 )
StaticVector<double,2UL> b;
b = real( a );

//
// \n \subsection vector_operations_cbrt cbrt() / invcbrt()
//
// The \c cbrt() and \c invcbrt() functions can be used to compute the the (inverse) cubic root

blaze::HybridVector<double,3UL> a, b, c;
b = cbrt( a ); // Computes the cubic root of each element
c = invcbrt( a ); // Computes the inverse cubic root of each element
\endcode
// Note that in case of sparse vectors only the non-zero elements are taken into account!
//
//
// \n \subsection vector_operations_clip clip()
//
// The \c clip() function can be used to restrict all elements of a vector to a specific range:

//
//
// \n \subsection vector_operations_pow pow()
//
// The \c pow() function can be used to compute the exponential value of each element of a vector:

b = pow( a, 1.2 ); // Computes the exponential value of each element
\endcode
// \n \subsection vector_operations_exp exp()
//

\endcode
// Note that in case of sparse vectors only the non-zero elements are taken into account!
//
//
// \n \subsection vector_operations_log log() / log10()
//
// The \c log() and \c log10() functions can be used to compute the natural and common logarithm
// of each element of a vector:

b = log( a ); // Computes the natural logarithm of each element
b = log10( a ); // Computes the common logarithm of each element
\endcode
// \n \subsection vector_operations_trigonometric_functions sin() / cos() / tan() / asin() / acos() / atan()
//
// The following trigonometric functions are available for both dense and sparse vectors:
\code
blaze::DynamicVector<double> a, b;
b = sin( a ); // Computes the sine of each element of the vector
b = cos( a ); // Computes the cosine of each element of the vector
b = tan( a ); // Computes the tangent of each element of the vector

// Note that in case of sparse vectors only the non-zero elements are taken into account!
//
//
// \n \subsection vector_operations_hyperbolic_functions sinh() / cosh() / tanh() / asinh() / acosh() / atanh()
//
// The following hyperbolic functions are available for both dense and sparse vectors:
\code
blaze::DynamicVector<double> a, b;
b = sinh( a ); // Computes the hyperbolic sine of each element of the vector
b = cosh( a ); // Computes the hyperbolic cosine of each element of the vector
b = tanh( a ); // Computes the hyperbolic tangent of each element of the vector

// Note that in case of sparse vectors only the non-zero elements are taken into account!
//
//
// \n \subsection vector_operations_erf erf() / erfc()
//
// The \c erf() and \c erfc() functions compute the (complementary) error function of each

blaze::StaticVector<double,3UL,rowVector> a, b;
b = erf( a ); // Computes the error function of each element
b = erfc( a ); // Computes the complementary error function of each element
\endcode
// Note that in case of sparse vectors only the non-zero elements are taken into account!
//
//
// \n \subsection vector_operations_foreach forEach()
//
// Via the \c forEach() function it is possible to execute custom operations on dense and sparse
// vectors. For instance, the following example demonstrates a custom square root computation via
// a lambda:
\code
blaze::DynamicVector<double> a, b;
b = forEach( a, []( double d ) { return std::sqrt( d ); } );
\endcode
// Although the computation can be parallelized it is not vectorized and thus cannot perform at
// peak performance. However, it is also possible to create vectorized custom operations. See
// \ref custom_operations for a detailed overview of the possibilities of custom operations.
//
//
// \n \subsection vector_operations_length length() / sqrLength()
//
// In order to calculate the length of a vector, both the \c length() and \c sqrLength() function
// can be used:
\code
blaze::StaticVector<float,3UL,rowVector> v{ -1.2F, 2.7F, -2.3F };
const float len = length ( v ); // Computes the current length of the vector
const float sqrlen = sqrLength( v ); // Computes the square length of the vector
\endcode
// Note that both functions can only be used for vectors with built-in or complex element type!
//
//
// \n \subsection vector_operations_vector_transpose trans()
//
// As already mentioned, vectors can either be column vectors (blaze::columnVector) or row vectors
// (blaze::rowVector). A column vector cannot be assigned to a row vector and vice versa. However,
// vectors can be transposed via the \c trans() function:
\code
blaze::DynamicVector<int,columnVector> v1( 4UL );
blaze::CompressedVector<int,rowVector> v2( 4UL );
v1 = v2; // Compilation error: Cannot assign a row vector to a column vector
v1 = trans( v2 ); // OK: Transposing the row vector to a column vector and assigning it
// to the column vector v1
v2 = trans( v1 ); // OK: Transposing the column vector v1 and assigning it to the row vector v2
v1 += trans( v2 ); // OK: Addition assignment of two column vectors
\endcode
// \n \subsection vector_operations_conjugate_transpose ctrans()
//
// It is also possible to compute the conjugate transpose of a vector. This operation is available
// via the \c ctrans() function:
\code
blaze::CompressedVector< complex<float>, rowVector > v1( 4UL );
blaze::DynamicVector< complex<float>, columnVector > v2( 4UL );
v1 = ctrans( v2 ); // Compute the conjugate transpose vector
\endcode
// Note that the \c ctrans() function has the same effect as manually applying the \c conj() and
// \c trans() function in any order:
\code
v1 = trans( conj( v2 ) ); // Computing the conjugate transpose vector
v1 = conj( trans( v2 ) ); // Computing the conjugate transpose vector
\endcode
// \n \subsection vector_operations_normalize normalize()
//
// The \c normalize() function can be used to scale any non-zero vector to a length of 1. In
// case the vector does not contain a single non-zero element (i.e. is a zero vector), the
// \c normalize() function returns a zero vector.
\code
blaze::DynamicVector<float,columnVector> v1( 10UL );
blaze::CompressedVector<double,columnVector> v2( 12UL );
v1 = normalize( v1 ); // Normalizing the dense vector v1
length( v1 ); // Returns 1 (or 0 in case of a zero vector)
v1 = normalize( v2 ); // Assigning v1 the normalized vector v2
length( v1 ); // Returns 1 (or 0 in case of a zero vector)
\endcode
// Note that the \c normalize() function only works for floating point vectors. The attempt to
// use it for an integral vector results in a compile time error.
//
// \n \subsection vector_operations_swap swap()
//
// Via the \c swap() function it is possible to completely swap the contents of two vectors of
// the same type:
\code
blaze::DynamicVector<int,columnVector> v1( 10UL );
blaze::DynamicVector<int,columnVector> v2( 20UL );
swap( v1, v2 ); // Swapping the contents of v1 and v2

\endcode
// \n \section matrix_types_custom_matrix CustomMatrix
// <hr>
//
// The blaze::CustomMatrix class template provides the functionality to represent an external
// array of elements of arbitrary type and a fixed size as a native \b Blaze dense matrix data
// structure. Thus in contrast to all other dense matrix types a custom matrix does not perform
// any kind of memory allocation by itself, but it is provided with an existing array of element
// during construction. A custom matrix can therefore be considered an alias to the existing
// array. It can be included via the header file
\code
#include <blaze/math/CustomMatrix.h>
\endcode
// The type of the elements, the properties of the given array of elements and the storage order
// of the matrix can be specified via the following four template parameters:
\code
template< typename Type, bool AF, bool PF, bool SO >
class CustomMatrix;
\endcode
// - Type: specifies the type of the matrix elements. blaze::CustomMatrix can be used with
// any non-cv-qualified, non-reference, non-pointer element type.
// - AF : specifies whether the represented, external arrays are properly aligned with
// respect to the available instruction set (SSE, AVX, ...) or not.
// - PF : specified whether the represented, external arrays are properly padded with
// respect to the available instruction set (SSE, AVX, ...) or not.
// - SO : specifies the storage order (blaze::rowMajor, blaze::columnMajor) of the matrix.
// The default value is blaze::rowMajor.
//
// The blaze::CustomMatrix is the right choice if any external array needs to be represented as
// a \b Blaze dense matrix data structure or if a custom memory allocation strategy needs to be
// realized:
\code
using blaze::CustomMatrix;
using blaze::aligned;
using blaze::unaligned;
using blaze::padded;
using blaze::unpadded;
// Definition of an unmanaged 3x4 custom matrix for unaligned, unpadded integer arrays

UnalignedUnpadded A( &vec[0], 3UL, 4UL );
// Definition of a managed 5x6 custom matrix for unaligned but padded 'float' arrays

\endcode
// In comparison with the remaining \b Blaze dense matrix types blaze::CustomMatrix has several
// special characteristics. All of these result from the fact that a custom matrix is not
// performing any kind of memory allocation, but instead is given an existing array of elements.
// The following sections discuss all of these characteristics:
//
// -# <b>\ref matrix_types_custom_matrix_memory_management</b>
// -# <b>\ref matrix_types_custom_matrix_copy_operations</b>
// -# <b>\ref matrix_types_custom_matrix_alignment</b>
// -# <b>\ref matrix_types_custom_matrix_padding</b>
//
// \n \subsection matrix_types_custom_matrix_memory_management Memory Management
//
// The blaze::CustomMatrix class template acts as an adaptor for an existing array of elements. As
// such it provides everything that is required to use the array just like a native \b Blaze dense
// matrix data structure. However, this flexibility comes with the price that the user of a custom
// matrix is responsible for the resource management.
//
// When constructing a custom matrix there are two choices: Either a user manually manages the
// array of elements outside the custom matrix, or alternatively passes the responsibility for
// the memory management to an instance of CustomMatrix. In the second case the CustomMatrix
// class employs shared ownership between all copies of the custom matrix, which reference the
// same array.
//
// The following examples give an impression of several possible types of custom matrices:
\code
using blaze::CustomMatrix;
using blaze::ArrayDelete;
using blaze::Deallocate;
using blaze::allocate;
using blaze::aligned;
using blaze::unaligned;
using blaze::padded;
using blaze::unpadded;
using blaze::rowMajor;
using blaze::columnMajor;
// Definition of a 3x4 custom row-major matrix with unaligned, unpadded and externally
// managed integer array. Note that the std::vector must be guaranteed to outlive the
// custom matrix!
std::vector<int> vec( 12UL );
CustomMatrix<int,unaligned,unpadded> A( &vec[0], 3UL, 4UL );
// Definition of a 3x4 custom row-major matrix for unaligned, unpadded integer arrays.
// The responsibility for the memory management is passed to the custom matrix by
// providing a deleter of type 'blaze::ArrayDelete' that is used during the destruction
// of the custom matrix.
CustomMatrix<int,unaligned,unpadded,rowMajor> B( new int[12], 3UL, 4UL, ArrayDelete() );
// Definition of a custom 8x12 matrix for an aligned and padded integer array of
// capacity 128 (including 8 padding elements per row). The memory management is passed
// to the custom matrix by providing a deleter of type 'blaze::Deallocate'.
CustomMatrix<int,aligned,padded> C( allocate<int>( 128UL ), 8UL, 12UL, 16UL, Deallocate() );
\endcode
// It is possible to pass any type of deleter to the constructor. The deleter is only required
// to provide a function call operator that can be passed the pointer to the managed array. As
// an example the following code snipped shows the implementation of two native \b Blaze deleters
// blaze::ArrayDelete and blaze::Deallocate:
\code
namespace blaze {
struct ArrayDelete
{
template< typename Type >
inline void operator()( Type ptr ) const { boost::checked_array_delete( ptr ); }
};
struct Deallocate
{
template< typename Type >
inline void operator()( Type ptr ) const { deallocate( ptr ); }
};
} // namespace blaze
\endcode
// \n \subsection matrix_types_custom_matrix_copy_operations Copy Operations
//
// As with all dense matrices it is possible to copy construct a custom matrix:
\code
using blaze::CustomMatrix;
using blaze::unaligned;
using blaze::unpadded;
typedef CustomMatrix<int,unaligned,unpadded> CustomType;
std::vector<int> vec( 6UL, 10 ); // Vector of 6 integers of the value 10
CustomType A( &vec[0], 2UL, 3UL ); // Represent the std::vector as Blaze dense matrix
a[1] = 20; // Also modifies the std::vector
CustomType B( a ); // Creating a copy of vector a
b[2] = 20; // Also affect matrix A and the std::vector
\endcode
// It is important to note that a custom matrix acts as a reference to the specified array. Thus
// the result of the copy constructor is a new custom matrix that is referencing and representing
// the same array as the original custom matrix. In case a deleter has been provided to the first
// custom matrix, both matrices share the responsibility to destroy the array when the last matrix
// goes out of scope.
//
// In contrast to copy construction, just as with references, copy assignment does not change
// which array is referenced by the custom matrices, but modifies the values of the array:
\code
std::vector<int> vec2( 6UL, 4 ); // Vector of 6 integers of the value 4
CustomType C( &vec2[0], 2UL, 3UL ); // Represent the std::vector as Blaze dense matrix
A = C; // Copy assignment: Set all values of matrix A and B to 4.
\endcode
// \n \subsection matrix_types_custom_matrix_alignment Alignment
//
// In case the custom matrix is specified as \c aligned the passed array must adhere to some
// alignment restrictions based on the alignment requirements of the used data type and the
// used instruction set (SSE, AVX, ...). The restriction applies to the first element of each
// row/column: In case of a row-major matrix the first element of each row must be properly
// aligned, in case of a column-major matrix the first element of each column must be properly
// aligned. For instance, if a row-major matrix is used and AVX is active the first element of
// each row must be 32-bit aligned:
\code
using blaze::CustomMatrix;
using blaze::Deallocate;
using blaze::aligned;
using blaze::padded;
using blaze::rowMajor;
int* array = blaze::allocate<int>( 40UL ); // Is guaranteed to be 32-bit aligned
CustomMatrix<int,aligned,padded,rowMajor> A( array, 5UL, 6UL, 8UL, Deallocate() );
\endcode
// In the example, the row-major matrix has six columns. However, since with AVX eight integer
// values are loaded together the matrix is padded with two additional elements. This guarantees
// that the first element of each row is 32-bit aligned. In case the alignment requirements are
// violated, a \c std::invalid_argument exception is thrown.
//
// \n \subsection matrix_types_custom_matrix_padding Padding
//
// Adding padding elements to the end of each row/column can have a significant impact on the
// performance. For instance, assuming that AVX is available, then two aligned, padded, 3x3 double
// precision matrices can be added via three SIMD addition operations:
\code
using blaze::CustomMatrix;
using blaze::Deallocate;
using blaze::allocate;
using blaze::aligned;
using blaze::padded;
typedef CustomMatrix<double,aligned,padded> CustomType;
// Creating padded custom 3x3 matrix with an additional padding element in each row
CustomType A( allocate<double>( 12UL ), 3UL, 3UL, 4UL, Deallocate() );
CustomType B( allocate<double>( 12UL ), 3UL, 3UL, 4UL, Deallocate() );
CustomType C( allocate<double>( 12UL ), 3UL, 3UL, 4UL, Deallocate() );
// ... Initialization
C = A + B; // AVX-based matrix addition
\endcode
// In this example, maximum performance is possible. However, in case no padding elements are
// inserted a scalar addition has to be used:
\code
using blaze::CustomMatrix;
using blaze::Deallocate;
using blaze::allocate;
using blaze::aligned;
using blaze::unpadded;
typedef CustomMatrix<double,aligned,unpadded> CustomType;
// Creating unpadded custom 3x3 matrix
CustomType A( allocate<double>( 12UL ), 3UL, 3UL, 4UL, Deallocate() );
CustomType B( allocate<double>( 12UL ), 3UL, 3UL, 4UL, Deallocate() );
CustomType C( allocate<double>( 12UL ), 3UL, 3UL, 4UL, Deallocate() );
// ... Initialization
C = A + B; // Scalar matrix addition
\endcode
// Note that the construction of padded and unpadded aligned matrices looks identical. However,
// in case of padded matrices, \b Blaze will zero initialize the padding element and use them
// in all computations in order to achieve maximum performance. In case of an unpadded matrix
// \b Blaze will ignore the elements with the downside that it is not possible to load a complete
// row to an AVX register, which makes it necessary to fall back to a scalar addition.
//
// The number of padding elements is required to be sufficient with respect to the available
// instruction set: In case of an aligned padded custom matrix the added padding elements must
// guarantee that the total number of elements in each row/column is a multiple of the SIMD
// vector width. In case of an unaligned padded matrix the number of padding elements can be
// greater or equal the number of padding elements of an aligned padded custom matrix. In case
// the padding is insufficient with respect to the available instruction set, a
// \c std::invalid_argument exception is thrown.
//

// \n \section matrix_operations_constructors Constructors
// <hr>
//
// Matrices are just as easy and intuitive to create as vectors. Still, there are a few rules
// to be aware of:
// - In case the last template parameter (the storage order) is omitted, the matrix is per
// default stored in row-major order.
// - The elements of a \c StaticMatrix or \c HybridMatrix are default initialized (i.e. built-in
// data types are initialized to 0, class types are initialized via the default constructor).
// - Newly allocated elements of a \c DynamicMatrix or \c CompressedMatrix remain uninitialized
// if they are of built-in type and are default constructed if they are of class type.
//
// \n \subsection matrix_operations_default_construction Default Construction
\code
using blaze::StaticMatrix;
using blaze::DynamicMatrix;
using blaze::CompressedMatrix;
// All matrices can be default constructed. Whereas the size of
// a StaticMatrix is fixed via the second and third template
// parameter, the initial size of a constructed DynamicMatrix
// or CompressedMatrix is 0.
StaticMatrix<int,2UL,2UL> M1; // Instantiation of a 2x2 integer row-major
// matrix. All elements are initialized to 0.
DynamicMatrix<float> M2; // Instantiation of a single precision dynamic
// row-major matrix with 0 rows and 0 columns.
DynamicMatrix<double,columnMajor> M3; // Instantiation of a double precision dynamic
// column-major matrix with 0 rows and 0 columns.
CompressedMatrix<int> M4; // Instantiation of a compressed integer
// row-major matrix of size 0x0.
CompressedMatrix<double,columnMajor> M5; // Instantiation of a compressed double precision
// column-major matrix of size 0x0.
\endcode
// \n \subsection matrix_operations_size_construction Construction with Specific Size
//
// The \c DynamicMatrix, \c HybridMatrix, and \c CompressedMatrix classes offer a constructor
// that allows to immediately give the matrices a specific number of rows and columns:
\code
DynamicMatrix<int> M6( 5UL, 4UL ); // Instantiation of a 5x4 dynamic row-major
// matrix. The elements are not initialized.
HybridMatrix<double,5UL,9UL> M7( 3UL, 7UL ); // Instantiation of a 3x7 hybrid row-major
// matrix. The elements are not initialized.
CompressedMatrix<float,columnMajor> M8( 8UL, 6UL ); // Instantiation of an empty 8x6 compressed
// column-major matrix.
\endcode
// Note that dense matrices (in this case \c DynamicMatrix and \c HybridMatrix) immediately
// allocate enough capacity for all matrix elements. Sparse matrices on the other hand (in this
// example \c CompressedMatrix) merely acquire the size, but don't necessarily allocate memory.
//
//
// \n \subsection matrix_operations_initialization_constructors Initialization Constructors
//
// All dense matrix classes offer a constructor for a direct, homogeneous initialization of all
// matrix elements. In contrast, for sparse matrices the predicted number of non-zero elements
// can be specified.
\code
StaticMatrix<int,4UL,3UL,columnMajor> M9( 7 ); // Instantiation of a 4x3 integer column-major
// matrix. All elements are initialized to 7.
DynamicMatrix<float> M10( 2UL, 5UL, 2.0F ); // Instantiation of a 2x5 single precision row-major
// matrix. All elements are initialized to 2.0F.
CompressedMatrix<int> M11( 3UL, 4UL, 4 ); // Instantiation of a 3x4 integer row-major
// matrix with capacity for 4 non-zero elements.
\endcode
// \n \subsection matrix_operations_array_construction Array Construction
//
// Alternatively, all dense matrix classes offer a constructor for an initialization with a
// dynamic or static array. If the matrix is initialized from a dynamic array, the constructor
// expects the dimensions of values provided by the array as first and second argument, the
// array as third argument. In case of a static array, the fixed size of the array is used:
\code
const std::unique_ptr<double[]> array1( new double[6] );
// ... Initialization of the dynamic array
blaze::StaticMatrix<double,2UL,3UL> M12( 2UL, 3UL, array1.get() );
int array2[2][2] = { { 4, -5 }, { -6, 7 } };
blaze::StaticMatrix<int,2UL,2UL,rowMajor> M13( array2 );
\endcode
// \n \subsection matrix_operations_initializer_list_construction
//
// In addition, all dense matrix classes can be directly initialized by means of an initializer
// list:
\code
blaze::DynamicMatrix<float,columnMajor> M14{ { 3.1F, 6.4F },
{ -0.9F, -1.2F },
{ 4.8F, 0.6F } };
\endcode
// \n \subsection matrix_operations_copy_construction Copy Construction
//
// All dense and sparse matrices can be created as a copy of another dense or sparse matrix.
\code
StaticMatrix<int,5UL,4UL,rowMajor> M15( M6 ); // Instantiation of the dense row-major matrix M15
// as copy of the dense row-major matrix M6.
DynamicMatrix<float,columnMajor> M16( M8 ); // Instantiation of the dense column-major matrix M16
// as copy of the sparse column-major matrix M8.
CompressedMatrix<double,columnMajor> M17( M7 ); // Instantiation of the compressed column-major matrix
// M17 as copy of the dense row-major matrix M7.
CompressedMatrix<float,rowMajor> M18( M8 ); // Instantiation of the compressed row-major matrix
// M18 as copy of the compressed column-major matrix M8.
\endcode
// Note that it is not possible to create a \c StaticMatrix as a copy of a matrix with a different
// number of rows and/or columns:
\code
StaticMatrix<int,4UL,5UL,rowMajor> M19( M6 ); // Runtime error: Number of rows and columns
// does not match!
StaticMatrix<int,4UL,4UL,columnMajor> M20( M9 ); // Compile time error: Number of columns does
// not match!
\endcode
// \n \section matrix_operations_assignment Assignment
// <hr>
//
// There are several types of assignment to dense and sparse matrices:
// \ref matrix_operations_homogeneous_assignment, \ref matrix_operations_array_assignment,
// \ref matrix_operations_copy_assignment, and \ref matrix_operations_compound_assignment.
//
//
// \n \subsection matrix_operations_homogeneous_assignment Homogeneous Assignment
//
// It is possible to assign the same value to all elements of a dense matrix. All dense matrix
// classes provide an according assignment operator:
\code
blaze::StaticMatrix<int,3UL,2UL> M1;
blaze::DynamicMatrix<double> M2;
// Setting all integer elements of the StaticMatrix to 4
M1 = 4;
// Setting all double precision elements of the DynamicMatrix to 3.5
M2 = 3.5
\endcode
// \n \subsection matrix_operations_array_assignment Array Assignment
//
// Dense matrices can also be assigned a static array:
\code
blaze::StaticMatrix<int,2UL,2UL,rowMajor> M1;
blaze::StaticMatrix<int,2UL,2UL,columnMajor> M2;
blaze::DynamicMatrix<double> M3;
int array1[2][2] = { { 1, 2 }, { 3, 4 } };
double array2[3][2] = { { 3.1, 6.4 }, { -0.9, -1.2 }, { 4.8, 0.6 } };
M1 = array1;
M2 = array1;
M3 = array2;
\endcode
// Note that the dimensions of the static array have to match the size of a \c StaticMatrix,
// whereas a \c DynamicMatrix is resized according to the array dimensions:
\f$ M3 = \left(\begin{array}{*{2}{c}}
3.1 & 6.4 \\
-0.9 & -1.2 \\
4.8 & 0.6 \\
\end{array}\right)\f$
// \n \subsection matrix_operations_initializer_list_assignment Initializer List Assignment
//
// Alternatively, it is possible to directly assign an initializer list to a dense matrix:
\code
blaze::DynamicMatrix<double> M;
M = { { 3.1, 6.4 }, { -0.9, -1.2 }, { 4.8, 0.6 } };
\endcode
// \n \subsection matrix_operations_copy_assignment Copy Assignment
//
// All kinds of matrices can be assigned to each other. The only restriction is that since a
// \c StaticMatrix cannot change its size, the assigned matrix must match both in the number of
// rows and in the number of columns.
\code
blaze::StaticMatrix<int,3UL,2UL,rowMajor> M1;
blaze::DynamicMatrix<int,rowMajor> M2( 3UL, 2UL );
blaze::DynamicMatrix<float,rowMajor> M3( 5UL, 2UL );
blaze::CompressedMatrix<int,rowMajor> M4( 3UL, 2UL );
blaze::CompressedMatrix<float,columnMajor> M5( 3UL, 2UL );
// ... Initialization of the matrices
M1 = M2; // OK: Assignment of a 3x2 dense row-major matrix to another 3x2 dense row-major matrix
M1 = M4; // OK: Assignment of a 3x2 sparse row-major matrix to a 3x2 dense row-major matrix
M1 = M3; // Runtime error: Cannot assign a 5x2 matrix to a 3x2 static matrix
M1 = M5; // OK: Assignment of a 3x2 sparse column-major matrix to a 3x2 dense row-major matrix
\endcode
// \n \subsection matrix_operations_compound_assignment Compound Assignment
//
// Compound assignment is also available for matrices: addition assignment, subtraction assignment,
// and multiplication assignment. In contrast to plain assignment, however, the number of rows
// and columns of the two operands have to match according to the arithmetic operation.
\code
blaze::StaticMatrix<int,2UL,3UL,rowMajor> M1;
blaze::DynamicMatrix<int,rowMajor> M2( 2UL, 3UL );
blaze::CompressedMatrix<float,columnMajor> M3( 2UL, 3UL );
blaze::CompressedMatrix<float,rowMajor> M4( 2UL, 4UL );
blaze::StaticMatrix<float,2UL,4UL,rowMajor> M5;
blaze::CompressedMatrix<float,rowMajor> M6( 3UL, 2UL );
// ... Initialization of the matrices
M1 += M2; // OK: Addition assignment between two row-major matrices of the same dimensions
M1 -= M3; // OK: Subtraction assignment between between a row-major and a column-major matrix
M1 += M4; // Runtime error: No compound assignment between matrices of different size
M1 -= M5; // Compilation error: No compound assignment between matrices of different size
M2 *= M6; // OK: Multiplication assignment between two row-major matrices
\endcode
// Note that the multiplication assignment potentially changes the number of columns of the
// target matrix:
\f$\left(\begin{array}{*{3}{c}}
2 & 0 & 1 \\
0 & 3 & 2 \\
\end{array}\right) \times
\left(\begin{array}{*{2}{c}}
4 & 0 \\
1 & 0 \\
0 & 3 \\
\end{array}\right) =
\left(\begin{array}{*{2}{c}}
8 & 3 \\
3 & 6 \\
\end{array}\right)\f$
// Since a \c StaticMatrix cannot change its size, only a square StaticMatrix can be used in a
// multiplication assignment with other square matrices of the same dimensions.
//
//
// \n \section matrix_operations_element_access Element Access
// <hr>
//
// The easiest way to access a specific dense or sparse matrix element is via the function call
// operator. The indices to access a matrix are zero-based:
\code
blaze::DynamicMatrix<int> M1( 4UL, 6UL );
M1(0,0) = 1;
M1(0,1) = 3;
// ...
blaze::CompressedMatrix<double> M2( 5UL, 3UL );
M2(0,2) = 4.1;
M2(1,1) = -6.3;
\endcode
// Since dense matrices allocate enough memory for all contained elements, using the function
// call operator on a dense matrix directly returns a reference to the accessed value. In case
// of a sparse matrix, if the accessed value is currently not contained in the matrix, the
// value is inserted into the matrix prior to returning a reference to the value, which can
// be much more expensive than the direct access to a dense matrix. Consider the following
// example:
\code
blaze::CompressedMatrix<int> M1( 4UL, 4UL );
for( size_t i=0UL; i<M1.rows(); ++i ) {
for( size_t j=0UL; j<M1.columns(); ++j ) {
... = M1(i,j);
}
}
\endcode
// Although the compressed matrix is only used for read access within the for loop, using the
// function call operator temporarily inserts 16 non-zero elements into the matrix. Therefore,
// all matrices (sparse as well as dense) offer an alternate way via the \c begin(), \c cbegin(),
// \c end() and \c cend() functions to traverse all contained elements by iterator. Note that
// it is not possible to traverse all elements of the matrix, but that it is only possible to
// traverse elements in a row/column-wise fashion. In case of a non-const matrix, \c begin() and
// \c end() return an \c Iterator, which allows a manipulation of the non-zero value, in case of
// a constant matrix or in case \c cbegin() or \c cend() are used a \c ConstIterator is returned:
\code
using blaze::CompressedMatrix;
CompressedMatrix<int,rowMajor> M1( 4UL, 6UL );
// Traversing the matrix by Iterator
for( size_t i=0UL; i<A.rows(); ++i ) {
for( CompressedMatrix<int,rowMajor>::Iterator it=A.begin(i); it!=A.end(i); ++it ) {
it->value() = ...; // OK: Write access to the value of the non-zero element.
... = it->value(); // OK: Read access to the value of the non-zero element.
it->index() = ...; // Compilation error: The index of a non-zero element cannot be changed.
... = it->index(); // OK: Read access to the index of the non-zero element.
}
}
// Traversing the matrix by ConstIterator
for( size_t i=0UL; i<A.rows(); ++i ) {
for( CompressedMatrix<int,rowMajor>::ConstIterator it=A.cbegin(i); it!=A.cend(i); ++it ) {
it->value() = ...; // Compilation error: Assignment to the value via a ConstIterator is invalid.
... = it->value(); // OK: Read access to the value of the non-zero element.
it->index() = ...; // Compilation error: The index of a non-zero element cannot be changed.
... = it->index(); // OK: Read access to the index of the non-zero element.
}
}
\endcode
// Note that \c begin(), \c cbegin(), \c end(), and \c cend() are also available as free functions:
\code
for( size_t i=0UL; i<A.rows(); ++i ) {
for( CompressedMatrix<int,rowMajor>::Iterator it=begin( A, i ); it!=end( A, i ); ++it ) {
// ...
}
}
for( size_t i=0UL; i<A.rows(); ++i ) {
for( CompressedMatrix<int,rowMajor>::ConstIterator it=cbegin( A, i ); it!=cend( A, i ); ++it ) {
// ...
}
}
\endcode
// \n \section matrix_operations_element_insertion Element Insertion
// <hr>
//
// Whereas a dense matrix always provides enough capacity to store all matrix elements, a sparse
// matrix only stores the non-zero elements. Therefore it is necessary to explicitly add elements
// to the matrix. The first possibility to add elements to a sparse matrix is the function call
// operator:
\code
using blaze::CompressedMatrix;
CompressedMatrix<int> M1( 3UL, 4UL );
M1(1,2) = 9;
\endcode
// In case the element at the given position is not yet contained in the sparse matrix, it is
// automatically inserted. Otherwise the old value is replaced by the new value 2. The operator
// returns a reference to the sparse vector element.\n
// An alternative is the \c set() function: In case the element is not yet contained in the matrix
// the element is inserted, else the element's value is modified:
\code
// Insert or modify the value at position (2,0)
M1.set( 2, 0, 1 );
\endcode
// However, insertion of elements can be better controlled via the \c insert() function. In
// contrast to the function call operator and the \c set() function it emits an exception in case
// the element is already contained in the matrix. In order to check for this case, the \c find()
// function can be used:
\code
// In case the element at position (2,3) is not yet contained in the matrix it is inserted
// with a value of 4.
if( M1.find( 2, 3 ) == M1.end( 2 ) )
M1.insert( 2, 3, 4 );
\endcode
// Although the \c insert() function is very flexible, due to performance reasons it is not
// suited for the setup of large sparse matrices. A very efficient, yet also very low-level
// way to fill a sparse matrix is the \c append() function. It requires the sparse matrix to
// provide enough capacity to insert a new element in the specified row. Additionally, the
// index of the new element must be larger than the index of the previous element in the same
// row. Violating these conditions results in undefined behavior!
\code
M1.reserve( 0, 3 ); // Reserving space for three non-zero elements in row 0
M1.append( 0, 1, 2 ); // Appending the element 2 in row 0 at column index 1
M1.append( 0, 2, -4 ); // Appending the element -4 in row 0 at column index 2
// ...
\endcode
// The most efficient way to fill a sparse matrix with elements, however, is a combination of
// \c reserve(), \c append(), and the \c finalize() function:
\code
blaze::CompressedMatrix<int> M1( 3UL, 5UL );
M1.reserve( 3 ); // Reserving enough space for 3 non-zero elements
M1.append( 0, 1, 1 ); // Appending the value 1 in row 0 with column index 1
M1.finalize( 0 ); // Finalizing row 0
M1.append( 1, 1, 2 ); // Appending the value 2 in row 1 with column index 1
M1.finalize( 1 ); // Finalizing row 1
M1.append( 2, 0, 3 ); // Appending the value 3 in row 2 with column index 0
M1.finalize( 2 ); // Finalizing row 2
\endcode
// \n \section matrix_operations_member_functions Member Functions
// <hr>
//
// \subsection matrix_operations_rows .rows()
//
// The current number of rows of a matrix can be acquired via the \c rows() member function:
\code
// Instantiating a dynamic matrix with 10 rows and 8 columns
blaze::DynamicMatrix<int> M1( 10UL, 8UL );
M1.rows(); // Returns 10
// Instantiating a compressed matrix with 8 rows and 12 columns
blaze::CompressedMatrix<double> M2( 8UL, 12UL );
M2.rows(); // Returns 8
\endcode
// Alternatively, the free functions \c rows() can be used to query the current number of rows of
// a matrix. In contrast to the member function, the free function can also be used to query the
// number of rows of a matrix expression:
\code
rows( M1 ); // Returns 10, i.e. has the same effect as the member function
rows( M2 ); // Returns 8, i.e. has the same effect as the member function
rows( M1 * M2 ); // Returns 10, i.e. the number of rows of the resulting matrix
\endcode
// \n \subsection matrix_operations_columns .columns()
//
// The current number of columns of a matrix can be acquired via the \c columns() member function:
\code
// Instantiating a dynamic matrix with 6 rows and 8 columns
blaze::DynamicMatrix<int> M1( 6UL, 8UL );
M1.columns(); // Returns 8
// Instantiating a compressed matrix with 8 rows and 7 columns
blaze::CompressedMatrix<double> M2( 8UL, 7UL );
M2.columns(); // Returns 7
\endcode
// There is also a free function \c columns() available, which can also be used to query the number
// of columns of a matrix expression:
\code
columns( M1 ); // Returns 8, i.e. has the same effect as the member function
columns( M2 ); // Returns 7, i.e. has the same effect as the member function
columns( M1 * M2 ); // Returns 7, i.e. the number of columns of the resulting matrix
\endcode
// \n \subsection matrix_operations_capacity .capacity()
//
// The \c capacity() member function returns the internal capacity of a dense or sparse matrix.
// Note that the capacity of a matrix doesn't have to be equal to the size of a matrix. In case of
// a dense matrix the capacity will always be greater or equal than the total number of elements
// of the matrix. In case of a sparse matrix, the capacity will usually be much less than the
// total number of elements.
\code
blaze::DynamicMatrix<float> M1( 5UL, 7UL );
blaze::StaticMatrix<float,7UL,4UL> M2;
M1.capacity(); // Returns at least 35
M2.capacity(); // Returns at least 28
\endcode
// There is also a free function \c capacity() available to query the capacity. However, please
// note that this function cannot be used to query the capacity of a matrix expression:
\code
capacity( M1 ); // Returns at least 35, i.e. has the same effect as the member function
capacity( M2 ); // Returns at least 28, i.e. has the same effect as the member function
capacity( M1 * M2 ); // Compilation error!
\endcode
// \n \subsection matrix_operations_nonzeros .nonZeros()
//
// For both dense and sparse matrices the current number of non-zero elements can be queried
// via the \c nonZeros() member function. In case of matrices there are two flavors of the
// \c nonZeros() function: One returns the total number of non-zero elements in the matrix,
// the second returns the number of non-zero elements in a specific row (in case of a row-major
// matrix) or column (in case of a column-major matrix). Sparse matrices directly return their
// number of non-zero elements, dense matrices traverse their elements and count the number of
// non-zero elements.
\code
blaze::DynamicMatrix<int,rowMajor> M1( 3UL, 5UL );
// ... Initializing the dense matrix
M1.nonZeros(); // Returns the total number of non-zero elements in the dense matrix
M1.nonZeros( 2 ); // Returns the number of non-zero elements in row 2
\endcode
\code
blaze::CompressedMatrix<double,columnMajor> M2( 4UL, 7UL );
// ... Initializing the sparse matrix
M2.nonZeros(); // Returns the total number of non-zero elements in the sparse matrix
M2.nonZeros( 3 ); // Returns the number of non-zero elements in column 3
\endcode
// The free \c nonZeros() function can also be used to query the number of non-zero elements in a
// matrix expression. However, the result is not the exact number of non-zero elements, but may be
// a rough estimation:
\code
nonZeros( M1 ); // Has the same effect as the member function
nonZeros( M1, 2 ); // Has the same effect as the member function
nonZeros( M2 ); // Has the same effect as the member function
nonZeros( M2, 3 ); // Has the same effect as the member function
nonZeros( M1 * M2 ); // Estimates the number of non-zero elements in the matrix expression
\endcode
// \n \subsection matrix_operations_resize_reserve .resize() / .reserve()
//
// The dimensions of a \c StaticMatrix are fixed at compile time by the second and third template
// parameter and a \c CustomMatrix cannot be resized. In contrast, the number or rows and columns
// of \c DynamicMatrix, \c HybridMatrix, and \c CompressedMatrix can be changed at runtime:
\code
using blaze::DynamicMatrix;
using blaze::CompressedMatrix;
DynamicMatrix<int,rowMajor> M1;
CompressedMatrix<int,columnMajor> M2( 3UL, 2UL );
// Adapting the number of rows and columns via the resize() function. The (optional)
// third parameter specifies whether the existing elements should be preserved.
M1.resize( 2UL, 2UL ); // Resizing matrix M1 to 2x2 elements. Elements of built-in type
// remain uninitialized, elements of class type are default
// constructed.
M1.resize( 3UL, 1UL, false ); // Resizing M1 to 3x1 elements. The old elements are lost, the
// new elements are NOT initialized!
M2.resize( 5UL, 7UL, true ); // Resizing M2 to 5x7 elements. The old elements are preserved.
M2.resize( 3UL, 2UL, false ); // Resizing M2 to 3x2 elements. The old elements are lost.
\endcode
// Note that resizing a matrix invalidates all existing views (see e.g. \ref views_submatrices)

typedef blaze::DynamicMatrix<int,rowMajor> MatrixType;
typedef blaze::Row<MatrixType> RowType;
MatrixType M1( 10UL, 20UL ); // Creating a 10x20 matrix
RowType row8 = row( M1, 8UL ); // Creating a view on the 8th row of the matrix
M1.resize( 6UL, 20UL ); // Resizing the matrix invalidates the view
\endcode
// When the internal capacity of a matrix is no longer sufficient, the allocation of a larger
// junk of memory is triggered. In order to avoid frequent reallocations, the \c reserve()
// function can be used up front to set the internal capacity:
\code
blaze::DynamicMatrix<int> M1;
M1.reserve( 100 );
M1.rows(); // Returns 0
M1.capacity(); // Returns at least 100
\endcode
// Additionally it is possible to reserve memory in a specific row (for a row-major matrix) or

// \n \section matrix_operations_free_functions Free Functions

//
// \subsection matrix_operations_reset_clear reset() / clear
//
// In order to reset all elements of a dense or sparse matrix, the \c reset() function can be

\endcode
// In order to reset a row of a column-major matrix or a column of a row-major matrix, use a

//
// In order to return a matrix to its default state (i.e. the state of a default constructed

\code
// Setting up a single precision row-major matrix, whose elements are initialized with 2.0F.
blaze::DynamicMatrix<float> M1( 4UL, 5UL, 2.0F );

// Alternatively, an in-place inversion of a dense matrix can be performed via the \c invert()
// function:
\code
blaze::DynamicMatrix<double,blaze::rowMajor> A;
// ... Resizing and initialization
invert( A ); // In-place matrix inversion
\endcode
// Both the \c inv() and the \c invert() functions will automatically select the most suited matrix
// inversion algorithm depending on the size and type of the given matrix. For small matrices of
// up to 6x6, both functions use manually optimized kernels for maximum performance. For matrices
// larger than 6x6 the inversion is performed by means of the most suited matrix decomposition
// method: In case of a general matrix the LU decomposition is used, for symmetric matrices the
// LDLT decomposition is applied, for Hermitian matrices the LDLH decomposition is performed, and
// for triangular matrices the inverse is computed via a forward or back substitution.
//
// In case the type of the matrix does not provide additional compile time information about its
// structure (symmetric, lower, upper, diagonal, ...), the information can be provided manually
// when calling the \c invert() function:
\code

invert<asUpper> ( A ); // In-place inversion of a upper triangular matrix
invert<asUniUpper> ( A ); // In-place inversion of a upper unitriangular matrix
invert<asDiagonal> ( A ); // In-place inversion of a diagonal matrix
\endcode
// Alternatively, via the \c invert() function it is possible to explicitly specify the inversion
// algorithm:
\code
using blaze::byLU;
using blaze::byLDLT;
using blaze::byLDLH;
using blaze::byLLH;
// In-place inversion of a general matrix by means of an LU decomposition
invert<byLU>( A );

// In-place inversion of a Hermitian indefinite matrix by means of a Bunch-Kaufman decomposition
invert<byLDLH>( A );
// In-place inversion of a positive definite matrix by means of a Cholesky decomposition
invert<byLLH>( A );
\endcode
// Whereas the inversion by means of an LU decomposition works for every general square matrix,
// the inversion by LDLT only works for symmetric indefinite matrices, the inversion by LDLH is
// restricted to Hermitian indefinite matrices and the Cholesky decomposition (LLH) only works
// for Hermitian positive definite matrices. Please note that it is in the responsibility of the
// function caller to guarantee that the selected algorithm is suited for the given matrix. In
// case this precondition is violated the result can be wrong and might not represent the inverse
// of the given matrix!
//
// For both the \c inv() and \c invert() function the matrix inversion fails if ...
//
// - ... the given matrix is not a square matrix;
// - ... the given matrix is singular and not invertible.
//
// In all failure cases either a compilation error is created if the failure can be predicted at
// compile time or a \c std::invalid_argument exception is thrown.
//
// \note The matrix inversion can only be used for dense matrices with \c float, \c double,
// \c complex<float> or \c complex<double> element type. The attempt to call the function with

//
// \note The functions invert the dense matrix by means of LAPACK kernels. Thus the functions can
// only be used if the fitting LAPACK library is available and linked to the executable. Otherwise
// a linker error will be created.

// \note It is not possible to use any kind of view on the expression object returned by the
// \c inv() function. Also, it is not possible to access individual elements via the function call
// operator on the expression object:

\endcode
// The function works for both \c rowMajor and \c columnMajor matrices. Note, however, that the

// note that the way the permutation matrix \c P needs to be applied differs between row-major and
// column-major matrices, since the algorithm uses column interchanges for row-major matrices and
// row interchanges for column-major matrices.
//
// Furthermore, \c lu() can be used with adaptors. For instance, the following example demonstrates

// The QL decomposition of a dense matrix can be computed via the \c ql() function:

//
// Adaptors act as wrappers around the general \ref matrix_types. They adapt the interface of the
// matrices such that certain invariants are preserved. Due to this adaptors can provide a compile
// time guarantee of certain properties, which can be exploited for optimized performance.
//
// The \b Blaze library provides a total of 9 different adaptors:

// </li>
// </ul>
//
// In combination with the general matrix types, \b Blaze provides a total of 40 different matrix
// types that make it possible to exactly adapt the type of matrix to every specific problem.
//
//
// \n \section adaptors_examples Examples
// <hr>
//
// The following code examples give an impression on the use of adaptors. The first example shows
// the multiplication between two lower matrices:
\code
using blaze::DynamicMatrix;
using blaze::LowerMatrix;
using blaze::rowMajor;
using blaze::columnMajor;
LowerMatrix< DynamicMatrix<double,rowMajor> > A;
LowerMatrix< DynamicMatrix<double,columnMajor> > B;
DynamicMatrix<double,columnMajor> C;
// ... Resizing and initialization
C = A * B;
\endcode
// When multiplying two matrices, at least one of which is triangular, \b Blaze can exploit the
// fact that either the lower or upper part of the matrix contains only default elements and
// restrict the algorithm to the non-zero elements. Thus the adaptor provides a significant
// performance advantage in comparison to a general matrix multiplication, especially for large
// matrices.
//
// The second example shows the \c SymmetricMatrix adaptor in a row-major dense matrix/sparse
// vector multiplication:
\code
using blaze::DynamicMatrix;
using blaze::DynamicVector;
using blaze::CompressedVector;
using blaze::rowMajor;
using blaze::columnVector;
SymmetricMatrix< DynamicMatrix<double,rowMajor> > A;
CompressedVector<double,columnVector> x;
DynamicVector<double,columnVector> y;
// ... Resizing and initialization
y = A * x;
\endcode
// In this example it is not intuitively apparent that using a row-major matrix is not the best
// possible choice in terms of performance since the computation cannot be vectorized. Choosing
// a column-major matrix instead, however, would enable a vectorized computation. Therefore
// \b Blaze exploits the fact that \c A is symmetric, selects the best suited storage order and
// evaluates the multiplication as
\code
y = trans( A ) * x;
\endcode
// which significantly increases the performance.

// \n \section adaptors_symmetric_matrices_general Symmetric Matrices
// <hr>
//
// In contrast to general matrices, which have no restriction in their number of rows and columns
// and whose elements can have any value, symmetric matrices provide the compile time guarantee
// to be square matrices with pair-wise identical values. Mathematically, this means that a
// symmetric matrix is always equal to its transpose (\f$ A = A^T \f$) and that all non-diagonal
// values have an identical counterpart (\f$ a_{ij} == a_{ji} \f$). This symmetry property can
// be exploited to provide higher efficiency and/or lower memory consumption. Within the \b Blaze
// library, symmetric matrices are realized by the \ref adaptors_symmetric_matrices_symmetricmatrix
// class template.
//
//
// \n \section adaptors_symmetric_matrices_symmetricmatrix SymmetricMatrix
// <hr>
//
// The SymmetricMatrix class template is an adapter for existing dense and sparse matrix types.
// It inherits the properties and the interface of the given matrix type \c MT and extends it
// by enforcing the additional invariant of symmetry (i.e. the matrix is always equal to its
// transpose \f$ A = A^T \f$). It can be included via the header file
\code
#include <blaze/math/SymmetricMatrix.h>
\endcode
// The type of the adapted matrix can be specified via template parameter:
\code
template< typename MT >
class SymmetricMatrix;
\endcode
// \c MT specifies the type of the matrix to be adapted. SymmetricMatrix can be used with any
// non-cv-qualified, non-reference, non-pointer, non-expression dense or sparse matrix type. Note
// that the given matrix type must be either resizable (as for instance blaze::HybridMatrix or
// blaze::DynamicMatrix) or must be square at compile time (as for instance blaze::StaticMatrix).
//
// The following examples give an impression of several possible symmetric matrices:
\code
using blaze::unaligned;
using blaze::unpadded;
using blaze::rowMajor;
using blaze::columnMajor;
// Definition of a 3x3 row-major dense symmetric matrix with static memory
blaze::SymmetricMatrix< blaze::StaticMatrix<int,3UL,3UL,rowMajor> > A;
// Definition of a resizable column-major dense symmetric matrix based on HybridMatrix

// Definition of a compressed row-major single precision symmetric matrix
blaze::SymmetricMatrix< blaze::CompressedMatrix<float,blaze::rowMajor> > E;
\endcode
// The storage order of a symmetric matrix is depending on the storage order of the adapted matrix
// type \c MT. In case the adapted matrix is stored in a row-wise fashion (i.e. is specified as
// blaze::rowMajor), the symmetric matrix will also be a row-major matrix. Otherwise, if the
// adapted matrix is column-major (i.e. is specified as blaze::columnMajor), the symmetric matrix
// will also be a column-major matrix.
//
//
// \n \section adaptors_symmetric_matrices_special_properties Special Properties of Symmetric Matrices
// <hr>
//
// A symmetric matrix is used exactly like a matrix of the underlying, adapted matrix type \c MT.

// some important exceptions resulting from the symmetry constraint:
//
// -# <b>\ref adaptors_symmetric_matrices_square</b>
// -# <b>\ref adaptors_symmetric_matrices_symmetry</b>
// -# <b>\ref adaptors_symmetric_matrices_initialization</b>
//
// \n \subsection adaptors_symmetric_matrices_square Symmetric Matrices Must Always be Square!
//
// In case a resizable matrix is used (as for instance blaze::HybridMatrix, blaze::DynamicMatrix,
// or blaze::CompressedMatrix), this means that the according constructors, the \c resize() and
// the \c extend() functions only expect a single parameter, which specifies both the number of
// rows and columns, instead of two (one for the number of rows and one for the number of columns):
\code
using blaze::DynamicMatrix;
using blaze::SymmetricMatrix;
using blaze::rowMajor;
// Default constructed, default initialized, row-major 3x3 symmetric dynamic matrix
SymmetricMatrix< DynamicMatrix<double,rowMajor> > A( 3 );
// Resizing the matrix to 5x5
A.resize( 5 );
// Extending the number of rows and columns by 2, resulting in a 7x7 matrix
A.extend( 2 );
\endcode
// In case a matrix with a fixed size is used (as for instance blaze::StaticMatrix), the number
// of rows and number of columns must be specified equally:
\code
using blaze::StaticMatrix;
using blaze::SymmetricMatrix;
using blaze::columnMajor;
// Correct setup of a fixed size column-major 3x3 symmetric static matrix
SymmetricMatrix< StaticMatrix<int,3UL,3UL,columnMajor> > A;
// Compilation error: the provided matrix type is not a square matrix type
SymmetricMatrix< StaticMatrix<int,3UL,4UL,columnMajor> > B;
\endcode
// \n \subsection adaptors_symmetric_matrices_symmetry The Symmetric Property is Always Enforced!
//
// This means that modifying the element \f$ a_{ij} \f$ of a symmetric matrix also modifies its
// counterpart element \f$ a_{ji} \f$. Also, it is only possible to assign matrices that are
// symmetric themselves:
\code
using blaze::CompressedMatrix;
using blaze::DynamicMatrix;
using blaze::StaticMatrix;
using blaze::SymmetricMatrix;
using blaze::rowMajor;
// Default constructed, row-major 3x3 symmetric compressed matrix
SymmetricMatrix< CompressedMatrix<double,rowMajor> > A( 3 );
// Initializing three elements via the function call operator
A(0,0) = 1.0; // Initialization of the diagonal element (0,0)
A(0,2) = 2.0; // Initialization of the elements (0,2) and (2,0)
// Inserting three more elements via the insert() function
A.insert( 1, 1, 3.0 ); // Inserting the diagonal element (1,1)
A.insert( 1, 2, 4.0 ); // Inserting the elements (1,2) and (2,1)
// Access via a non-const iterator
*A.begin(1UL) = 10.0; // Modifies both elements (1,0) and (0,1)
// Erasing elements via the erase() function
A.erase( 0, 0 ); // Erasing the diagonal element (0,0)
A.erase( 0, 2 ); // Erasing the elements (0,2) and (2,0)
// Construction from a symmetric dense matrix
StaticMatrix<double,3UL,3UL> B{ { 3.0, 8.0, -2.0 },
{ 8.0, 0.0, -1.0 },
{ -2.0, -1.0, 4.0 } };
SymmetricMatrix< DynamicMatrix<double,rowMajor> > C( B ); // OK
// Assignment of a non-symmetric dense matrix
StaticMatrix<double,3UL,3UL> D{ { 3.0, 7.0, -2.0 },
{ 8.0, 0.0, -1.0 },
{ -2.0, -1.0, 4.0 } };
C = D; // Throws an exception; symmetric invariant would be violated!
\endcode
// The same restriction also applies to the \c append() function for sparse matrices: Appending
// the element \f$ a_{ij} \f$ additionally inserts the element \f$ a_{ji} \f$ into the matrix.
// Despite the additional insertion, the \c append() function still provides the most efficient
// way to set up a symmetric sparse matrix. In order to achieve the maximum efficiency, the
// capacity of the individual rows/columns of the matrix should to be specifically prepared with
// \c reserve() calls:
\code
using blaze::CompressedMatrix;
using blaze::SymmetricMatrix;
using blaze::rowMajor;
// Setup of the symmetric matrix
//
// ( 0 1 3 )
// A = ( 1 2 0 )
// ( 3 0 0 )
//
SymmetricMatrix< CompressedMatrix<double,rowMajor> > A( 3 );
A.reserve( 5 ); // Reserving enough space for 5 non-zero elements
A.reserve( 0, 2 ); // Reserving two non-zero elements in the first row
A.reserve( 1, 2 ); // Reserving two non-zero elements in the second row
A.reserve( 2, 1 ); // Reserving a single non-zero element in the third row
A.append( 0, 1, 1.0 ); // Appending the value 1 at position (0,1) and (1,0)
A.append( 1, 1, 2.0 ); // Appending the value 2 at position (1,1)
A.append( 2, 0, 3.0 ); // Appending the value 3 at position (2,0) and (0,2)
\endcode
// The symmetry property is also enforced for symmetric custom matrices: In case the given array
// of elements does not represent a symmetric matrix, a \c std::invalid_argument exception is
// thrown:
\code
using blaze::CustomMatrix;
using blaze::SymmetricMatrix;
using blaze::unaligned;
using blaze::unpadded;
using blaze::rowMajor;
typedef SymmetricMatrix< CustomMatrix<double,unaligned,unpadded,rowMajor> > CustomSymmetric;
// Creating a 3x3 symmetric custom matrix from a properly initialized array
double array[9] = { 1.0, 2.0, 4.0,
2.0, 3.0, 5.0,
4.0, 5.0, 6.0 };
CustomSymmetric A( array, 3UL ); // OK
// Attempt to create a second 3x3 symmetric custom matrix from an uninitialized array
CustomSymmetric B( new double[9UL], 3UL, blaze::ArrayDelete() ); // Throws an exception
\endcode
// Finally, the symmetry property is enforced for views (rows, columns, submatrices, ...) on the
// symmetric matrix. The following example demonstrates that modifying the elements of an entire
// row of the symmetric matrix also affects the counterpart elements in the according column of
// the matrix:
\code
using blaze::DynamicMatrix;
using blaze::SymmetricMatrix;
// Setup of the symmetric matrix
//
// ( 0 1 0 2 )
// A = ( 1 3 4 0 )
// ( 0 4 0 5 )
// ( 2 0 5 0 )
//
SymmetricMatrix< DynamicMatrix<int> > A( 4 );
A(0,1) = 1;
A(0,3) = 2;
A(1,1) = 3;
A(1,2) = 4;
A(2,3) = 5;
// Setting all elements in the 1st row to 0 results in the matrix
//
// ( 0 0 0 2 )
// A = ( 0 0 0 0 )
// ( 0 0 0 5 )
// ( 2 0 5 0 )
//
row( A, 1 ) = 0;
\endcode
// The next example demonstrates the (compound) assignment to submatrices of symmetric matrices.
// Since the modification of element \f$ a_{ij} \f$ of a symmetric matrix also modifies the
// element \f$ a_{ji} \f$, the matrix to be assigned must be structured such that the symmetry
// of the symmetric matrix is preserved. Otherwise a \c std::invalid_argument exception is
// thrown:
\code
using blaze::DynamicMatrix;
using blaze::SymmetricMatrix;
// Setup of two default 4x4 symmetric matrices
SymmetricMatrix< DynamicMatrix<int> > A1( 4 ), A2( 4 );
// Setup of the 3x2 dynamic matrix
//
// ( 1 2 )
// B = ( 3 4 )
// ( 5 6 )
//
DynamicMatrix<int> B{ { 1, 2 }, { 3, 4 }, { 5, 6 } };
// OK: Assigning B to a submatrix of A1 such that the symmetry can be preserved
//
// ( 0 0 1 2 )
// A1 = ( 0 0 3 4 )
// ( 1 3 5 6 )
// ( 2 4 6 0 )
//
submatrix( A1, 0UL, 2UL, 3UL, 2UL ) = B; // OK
// Error: Assigning B to a submatrix of A2 such that the symmetry cannot be preserved!
// The elements marked with X cannot be assigned unambiguously!
//
// ( 0 1 2 0 )
// A2 = ( 1 3 X 0 )
// ( 2 X 6 0 )
// ( 0 0 0 0 )
//
submatrix( A2, 0UL, 1UL, 3UL, 2UL ) = B; // Assignment throws an exception!
\endcode
// \n \subsection adaptors_symmetric_matrices_initialization The Elements of a Dense Symmetric Matrix are Always Default Initialized!
//
// Although this results in a small loss of efficiency (especially in case all default values are
// overridden afterwards), this property is important since otherwise the symmetric property of
// dense symmetric matrices could not be guaranteed:
\code
using blaze::DynamicMatrix;
using blaze::SymmetricMatrix;
// Uninitialized, 5x5 row-major dynamic matrix
DynamicMatrix<int,rowMajor> A( 5, 5 );
// Default initialized, 5x5 row-major symmetric dynamic matrix
SymmetricMatrix< DynamicMatrix<int,rowMajor> > B( 5 );
\endcode
// \n \section adaptors_symmetric_matrices_arithmetic_operations Arithmetic Operations
// <hr>
//
// A SymmetricMatrix matrix can participate in numerical operations in any way any other dense
// or sparse matrix can participate. It can also be combined with any other dense or sparse vector
// or matrix. The following code example gives an impression of the use of SymmetricMatrix within

using blaze::SymmetricMatrix;
using blaze::DynamicMatrix;
using blaze::StaticMatrix;
using blaze::CompressedMatrix;
using blaze::rowMajor;
using blaze::columnMajor;
CompressedMatrix<float> E( 3, 3 ); // Empty row-major sparse single precision 3x3 matrix
SymmetricMatrix< HybridMatrix<float,3UL,3UL,rowMajor> > F;
SymmetricMatrix< StaticMatrix<float,3UL,3UL,columnMajor> > G;
F = A + B; // Matrix addition and assignment to a row-major symmetric matrix
G = A - C; // Matrix subtraction and assignment to a column-major symmetric matrix
G = A * E; // Matrix multiplication between a dense and a sparse matrix
A *= 2.0; // In-place scaling of matrix A
F = 2.0 * B; // Scaling of matrix B
G = E * 2.0; // Scaling of matrix E
F += A - B; // Addition assignment
G -= A + C; // Subtraction assignment
G *= A * E; // Multiplication assignment
\endcode
// \n \section adaptors_symmetric_matrices_block_matrices Symmetric Block Matrices
// <hr>
//
// It is also possible to use symmetric block matrices:
\code
using blaze::CompressedMatrix;
using blaze::StaticMatrix;
using blaze::SymmetricMatrix;
// Definition of a 3x3 symmetric block matrix based on CompressedMatrix
SymmetricMatrix< CompressedMatrix< StaticMatrix<int,3UL,3UL> > > A( 3 );
\endcode
// Also in this case, the SymmetricMatrix class template enforces the invariant of symmetry and
// guarantees that a modifications of element \f$ a_{ij} \f$ of the adapted matrix is also
// applied to element \f$ a_{ji} \f$:
\code
// Inserting the elements (2,4) and (4,2)
A.insert( 2, 4, StaticMatrix<int,3UL,3UL>{ { 1, -4, 5 },
{ 6, 8, -3 },
{ 2, -1, 2 } } );
// Manipulating the elements (2,4) and (4,2)
A(2,4)(1,1) = -5;
\endcode
// For more information on block matrices, see the tutorial on \ref block_vectors_and_matrices.
//
//
// \n \section adaptors_symmetric_matrices_performance Performance Considerations
// <hr>
//
// When the symmetric property of a matrix is known beforehands using the SymmetricMatrix adaptor
// instead of a general matrix can be a considerable performance advantage. The \b Blaze library
// tries to exploit the properties of symmetric matrices whenever possible. However, there are
// also situations when using a symmetric matrix introduces some overhead. The following examples
// demonstrate several situations where symmetric matrices can positively or negatively impact
// performance.
//
// \n \subsection adaptors_symmetric_matrices_matrix_matrix_multiplication Positive Impact: Matrix/Matrix Multiplication
//
// When multiplying two matrices, at least one of which is symmetric, \b Blaze can exploit the fact
// that \f$ A = A^T \f$ and choose the fastest and most suited combination of storage orders for the
// multiplication. The following example demonstrates this by means of a dense matrix/sparse matrix
// multiplication:
\code
using blaze::DynamicMatrix;
using blaze::SymmetricMatrix;
using blaze::rowMajor;
using blaze::columnMajor;
SymmetricMatrix< DynamicMatrix<double,rowMajor> > A;
SymmetricMatrix< CompressedMatrix<double,columnMajor> > B;
DynamicMatrix<double,columnMajor> C;
// ... Resizing and initialization
C = A * B;
\endcode
// Intuitively, the chosen combination of a row-major and a column-major matrix is the most suited
// for maximum performance. However, \b Blaze evaluates the multiplication as
\code
C = A * trans( B );
\endcode
// which significantly increases the performance since in contrast to the original formulation the
// optimized form can be vectorized. Therefore, in the context of matrix multiplications, using the
// SymmetricMatrix adapter is obviously an advantage.
//
// \n \subsection adaptors_symmetric_matrices_matrix_vector_multiplication Positive Impact: Matrix/Vector Multiplication
//
// A similar optimization is possible in case of matrix/vector multiplications:
\code
using blaze::DynamicMatrix;
using blaze::DynamicVector;
using blaze::CompressedVector;
using blaze::rowMajor;
using blaze::columnVector;
SymmetricMatrix< DynamicMatrix<double,rowMajor> > A;
CompressedVector<double,columnVector> x;
DynamicVector<double,columnVector> y;
// ... Resizing and initialization
y = A * x;
\endcode
// In this example it is not intuitively apparent that using a row-major matrix is not the best
// possible choice in terms of performance since the computation cannot be vectorized. Choosing
// a column-major matrix instead, however, would enable a vectorized computation. Therefore
// \b Blaze exploits the fact that \c A is symmetric, selects the best suited storage order and
// evaluates the multiplication as
\code
y = trans( A ) * x;
\endcode
// which also significantly increases the performance.
//
// \n \subsection adaptors_symmetric_matrices_views Positive Impact: Row/Column Views on Column/Row-Major Matrices
//
// Another example is the optimization of a row view on a column-major symmetric matrix:
\code
using blaze::DynamicMatrix;
using blaze::SymmetricMatrix;
using blaze::Row;
using blaze::rowMajor;
using blaze::columnMajor;
typedef SymmetricMatrix< DynamicMatrix<double,columnMajor> > DynamicSymmetric;
DynamicSymmetric A( 10UL );
Row<DynamicSymmetric> row5 = row( A, 5UL );
\endcode
// Usually, a row view on a column-major matrix results in a considerable performance decrease in
// comparison to a row view on a row-major matrix due to the non-contiguous storage of the matrix
// elements. However, in case of symmetric matrices, \b Blaze instead uses the according column of
// the matrix, which provides the same performance as if the matrix would be row-major. Note that
// this also works for column views on row-major matrices, where \b Blaze can use the according
// row instead of a column in order to provide maximum performance.
//
// \n \subsection adaptors_symmetric_matrices_assignment Negative Impact: Assignment of a General Matrix
//
// In contrast to using a symmetric matrix on the right-hand side of an assignment (i.e. for read
// access), which introduces absolutely no performance penalty, using a symmetric matrix on the
// left-hand side of an assignment (i.e. for write access) may introduce additional overhead when
// it is assigned a general matrix, which is not symmetric at compile time:
\code
using blaze::DynamicMatrix;
using blaze::SymmetricMatrix;
SymmetricMatrix< DynamicMatrix<double> > A, C;
DynamicMatrix<double> B;
B = A; // Only read-access to the symmetric matrix; no performance penalty
C = A; // Assignment of a symmetric matrix to another symmetric matrix; no runtime overhead
C = B; // Assignment of a general matrix to a symmetric matrix; some runtime overhead
\endcode
// When assigning a general, potentially not symmetric matrix to a symmetric matrix it is necessary
// to check whether the matrix is symmetric at runtime in order to guarantee the symmetry property
// of the symmetric matrix. In case it turns out to be symmetric, it is assigned as efficiently as
// possible, if it is not, an exception is thrown. In order to prevent this runtime overhead it is
// therefore generally advisable to assign symmetric matrices to other symmetric matrices.\n
// In this context it is especially noteworthy that in contrast to additions and subtractions the
// multiplication of two symmetric matrices does not necessarily result in another symmetric matrix:
\code
SymmetricMatrix< DynamicMatrix<double> > A, B, C;
C = A + B; // Results in a symmetric matrix; no runtime overhead
C = A - B; // Results in a symmetric matrix; no runtime overhead
C = A * B; // Is not guaranteed to result in a symmetric matrix; some runtime overhead
\endcode

// In addition to symmetric matrices, \b Blaze also provides an adaptor for Hermitian matrices.
// Hermitian matrices provide the compile time guarantee to be square matrices with pair-wise
// conjugate complex values. Mathematically, this means that an Hermitian matrix is always equal
// to its conjugate transpose (\f$ A = \overline{A^T} \f$) and that all non-diagonal values have
// a complex conjugate counterpart (\f$ a_{ij} == \overline{a_{ji}} \f$). Within the \b Blaze
// library, Hermitian matrices are realized by the \ref adaptors_hermitian_matrices_hermitianmatrix
// class template.
//
//
// \n \section adaptors_hermitian_matrices_hermitianmatrix HermitianMatrix
// <hr>
//
// The HermitianMatrix class template is an adapter for existing dense and sparse matrix types.
// It inherits the properties and the interface of the given matrix type \c MT and extends it by
// enforcing the additional invariant of Hermitian symmetry (i.e. the matrix is always equal to
// its conjugate transpose \f$ A = \overline{A^T} \f$). It can be included via the header file
\code
#include <blaze/math/HermitianMatrix.h>
\endcode
// The type of the adapted matrix can be specified via template parameter:
\code
template< typename MT >
class HermitianMatrix;
\endcode
// \c MT specifies the type of the matrix to be adapted. HermitianMatrix can be used with any
// non-cv-qualified, non-reference, non-pointer, non-expression dense or sparse matrix type. Also,
// the given matrix type must have numeric element types (i.e. all integral types except \c bool,
// floating point and complex types). Note that the given matrix type must be either resizable (as
// for instance blaze::HybridMatrix or blaze::DynamicMatrix) or must be square at compile time (as
// for instance blaze::StaticMatrix).
//
// The following examples give an impression of several possible Hermitian matrices:

using blaze::unpadded;
using blaze::rowMajor;
using blaze::columnMajor;
// Definition of a 3x3 row-major dense Hermitian matrix with static memory

\endcode
// The storage order of a Hermitian matrix is depending on the storage order of the adapted matrix
// type \c MT. In case the adapted matrix is stored in a row-wise fashion (i.e. is specified as
// blaze::rowMajor), the Hermitian matrix will also be a row-major matrix. Otherwise, if the
// adapted matrix is column-major (i.e. is specified as blaze::columnMajor), the Hermitian matrix
// will also be a column-major matrix.
//
//
// \n \section adaptors_hermitian_matrices_vs_symmetric_matrices Hermitian Matrices vs. Symmetric Matrices
//
// The blaze::HermitianMatrix adaptor and the blaze::SymmetricMatrix adaptor share several traits.
// However, there are a couple of differences, both from a mathematical point of view as well as
// from an implementation point of view.
//
// From a mathematical point of view, a matrix is called symmetric when it is equal to its
// transpose (\f$ A = A^T \f$) and it is called Hermitian when it is equal to its conjugate
// transpose (\f$ A = \overline{A^T} \f$). For matrices of real values, however, these two
// conditions coincide, which means that symmetric matrices of real values are also Hermitian
// and Hermitian matrices of real values are also symmetric.
//
// From an implementation point of view, \b Blaze restricts Hermitian matrices to numeric data
// types (i.e. all integral types except \c bool, floating point and complex types), whereas
// symmetric matrices can also be block matrices (i.e. can have vector or matrix elements).
// For built-in element types, the HermitianMatrix adaptor behaves exactly like the according
// SymmetricMatrix implementation. For complex element types, however, the Hermitian property
// is enforced (see also \ref adaptors_hermitian_matrices_hermitian).
\code
using blaze::DynamicMatrix;
using blaze::DynamicVector;
using blaze::HermitianMatrix;
using blaze::SymmetricMatrix;
// The following two matrices provide an identical experience (including performance)
HermitianMatrix< DynamicMatrix<double> > A; // Both Hermitian and symmetric
SymmetricMatrix< DynamicMatrix<double> > B; // Both Hermitian and symmetric
// The following two matrices will behave differently
HermitianMatrix< DynamicMatrix< complex<double> > > C; // Only Hermitian
SymmetricMatrix< DynamicMatrix< complex<double> > > D; // Only symmetric
// Hermitian block matrices are not allowed
HermitianMatrix< DynamicMatrix< DynamicVector<double> > > E; // Compilation error!
SymmetricMatrix< DynamicMatrix< DynamicVector<double> > > F; // Symmetric block matrix
\endcode
// \n \section adaptors_hermitian_matrices_special_properties Special Properties of Hermitian Matrices
// <hr>
//
// A Hermitian matrix is used exactly like a matrix of the underlying, adapted matrix type \c MT.
// It also provides (nearly) the same interface as the underlying matrix type. However, there are
// some important exceptions resulting from the Hermitian symmetry constraint:
//
// -# <b>\ref adaptors_hermitian_matrices_square</b>
// -# <b>\ref adaptors_hermitian_matrices_hermitian</b>
// -# <b>\ref adaptors_hermitian_matrices_initialization</b>
//
// \n \subsection adaptors_hermitian_matrices_square Hermitian Matrices Must Always be Square!
//
// In case a resizable matrix is used (as for instance blaze::HybridMatrix, blaze::DynamicMatrix,
// or blaze::CompressedMatrix), this means that the according constructors, the \c resize() and
// the \c extend() functions only expect a single parameter, which specifies both the number of
// rows and columns, instead of two (one for the number of rows and one for the number of columns):
\code
using blaze::DynamicMatrix;
using blaze::HermitianMatrix;
using blaze::rowMajor;
// Default constructed, default initialized, row-major 3x3 Hermitian dynamic matrix
HermitianMatrix< DynamicMatrix<std::complex<double>,rowMajor> > A( 3 );
// Resizing the matrix to 5x5
A.resize( 5 );
// Extending the number of rows and columns by 2, resulting in a 7x7 matrix
A.extend( 2 );
\endcode
// In case a matrix with a fixed size is used (as for instance blaze::StaticMatrix), the number
// of rows and number of columns must be specified equally:
\code
using blaze::StaticMatrix;
using blaze::HermitianMatrix;
using blaze::columnMajor;
// Correct setup of a fixed size column-major 3x3 Hermitian static matrix
HermitianMatrix< StaticMatrix<std::complex<float>,3UL,3UL,columnMajor> > A;
// Compilation error: the provided matrix type is not a square matrix type
HermitianMatrix< StaticMatrix<std::complex<float>,3UL,4UL,columnMajor> > B;
\endcode
// \n \subsection adaptors_hermitian_matrices_hermitian The Hermitian Property is Always Enforced!
//
// This means that the following properties of a Hermitian matrix are always guaranteed:
//
// - The diagonal elements are real numbers, i.e. the imaginary part is zero
// - Element \f$ a_{ij} \f$ is always the complex conjugate of element \f$ a_{ji} \f$
//
// Thus modifying the element \f$ a_{ij} \f$ of a Hermitian matrix also modifies its
// counterpart element \f$ a_{ji} \f$. Also, it is only possible to assign matrices that
// are Hermitian themselves:
\code
using blaze::CompressedMatrix;
using blaze::DynamicMatrix;
using blaze::StaticMatrix;
using blaze::HermitianMatrix;
using blaze::rowMajor;
typedef std::complex<double> cplx;

// Assignment of a non-Hermitian dense matrix
StaticMatrix<cplx,3UL,3UL> D{ { cplx( 3.0, 0.0 ), cplx( 7.0, 2.0 ), cplx( 3.0, 2.0 ) },
{ cplx( 8.0, 1.0 ), cplx( 0.0, 0.0 ), cplx( 6.0, 4.0 ) },
{ cplx( -2.0, 2.0 ), cplx( -1.0, 1.0 ), cplx( 4.0, 0.0 ) } };
C = D; // Throws an exception; Hermitian invariant would be violated!
\endcode
// The same restriction also applies to the \c append() function for sparse matrices: Appending
// the element \f$ a_{ij} \f$ additionally inserts the element \f$ a_{ji} \f$ into the matrix.
// Despite the additional insertion, the \c append() function still provides the most efficient
// way to set up a Hermitian sparse matrix. In order to achieve the maximum efficiency, the
// capacity of the individual rows/columns of the matrix should to be specifically prepared with
// \c reserve() calls:
\code
using blaze::CompressedMatrix;
using blaze::HermitianMatrix;
using blaze::rowMajor;
typedef std::complex<double> cplx;
// Setup of the Hermitian matrix
//
// ( (0, 0) (1,2) (3,-4) )
// A = ( (1,-2) (2,0) (0, 0) )
// ( (3, 4) (0,0) (0, 0) )
//
HermitianMatrix< CompressedMatrix<cplx,rowMajor> > A( 3 );
A.reserve( 5 ); // Reserving enough space for 5 non-zero elements
A.reserve( 0, 2 ); // Reserving two non-zero elements in the first row
A.reserve( 1, 2 ); // Reserving two non-zero elements in the second row
A.reserve( 2, 1 ); // Reserving a single non-zero element in the third row
A.append( 0, 1, cplx( 1.0, 2.0 ) ); // Appending an element at position (0,1) and (1,0)
A.append( 1, 1, cplx( 2.0, 0.0 ) ); // Appending an element at position (1,1)
A.append( 2, 0, cplx( 3.0, 4.0 ) ); // Appending an element at position (2,0) and (0,2)
\endcode
// The Hermitian property is also enforced for Hermitian custom matrices: In case the given array
// of elements does not represent a Hermitian matrix, a \c std::invalid_argument exception is
// thrown:
\code
using blaze::CustomMatrix;
using blaze::HermitianMatrix;
using blaze::unaligned;
using blaze::unpadded;
using blaze::rowMajor;
typedef HermitianMatrix< CustomMatrix<double,unaligned,unpadded,rowMajor> > CustomHermitian;
// Creating a 3x3 Hermitian custom matrix from a properly initialized array
double array[9] = { 1.0, 2.0, 4.0,
2.0, 3.0, 5.0,
4.0, 5.0, 6.0 };
CustomHermitian A( array, 3UL ); // OK
// Attempt to create a second 3x3 Hermitian custom matrix from an uninitialized array
CustomHermitian B( new double[9UL], 3UL, blaze::ArrayDelete() ); // Throws an exception
\endcode
// Finally, the Hermitian property is enforced for views (rows, columns, submatrices, ...) on the
// Hermitian matrix. The following example demonstrates that modifying the elements of an entire
// row of the Hermitian matrix also affects the counterpart elements in the according column of
// the matrix:
\code
using blaze::DynamicMatrix;
using blaze::HermtianMatrix;
typedef std::complex<double> cplx;
// Setup of the Hermitian matrix
//
// ( (0, 0) (1,-1) (0,0) (2, 1) )
// A = ( (1, 1) (3, 0) (4,2) (0, 0) )
// ( (0, 0) (4,-2) (0,0) (5,-3) )
// ( (2,-1) (0, 0) (5,3) (0, 0) )
//
HermitianMatrix< DynamicMatrix<int> > A( 4 );
A(0,1) = cplx( 1.0, -1.0 );
A(0,3) = cplx( 2.0, 1.0 );
A(1,1) = cplx( 3.0, 0.0 );
A(1,2) = cplx( 4.0, 2.0 );
A(2,3) = cplx( 5.0, 3.0 );
// Setting all elements in the 1st row to 0 results in the matrix
//
// ( (0, 0) (0,0) (0,0) (2, 1) )
// A = ( (0, 0) (0,0) (0,0) (0, 0) )
// ( (0, 0) (0,0) (0,0) (5,-3) )
// ( (2,-1) (0,0) (5,3) (0, 0) )
//
row( A, 1 ) = cplx( 0.0, 0.0 );
\endcode
// The next example demonstrates the (compound) assignment to submatrices of Hermitian matrices.
// Since the modification of element \f$ a_{ij} \f$ of a Hermitian matrix also modifies the
// element \f$ a_{ji} \f$, the matrix to be assigned must be structured such that the Hermitian
// symmetry of the matrix is preserved. Otherwise a \c std::invalid_argument exception is thrown:
\code
using blaze::DynamicMatrix;
using blaze::HermitianMatrix;
std::complex<double> cplx;
// Setup of two default 4x4 Hermitian matrices
HermitianMatrix< DynamicMatrix<cplx> > A1( 4 ), A2( 4 );
// Setup of the 3x2 dynamic matrix
//

// OK: Assigning B to a submatrix of A1 such that the Hermitian property is preserved

// Error: Assigning B to a submatrix of A2 such that the Hermitian property isn't preserved!
// The elements marked with X cannot be assigned unambiguously!

//
submatrix( A2, 0UL, 1UL, 3UL, 2UL ) = B; // Assignment throws an exception!
\endcode
// \n \subsection adaptors_hermitian_matrices_initialization The Elements of a Dense Hermitian Matrix are Always Default Initialized!
//
// Although this results in a small loss of efficiency (especially in case all default values are
// overridden afterwards), this property is important since otherwise the Hermitian property of
// dense Hermitian matrices could not be guaranteed:
\code
using blaze::DynamicMatrix;
using blaze::HermitianMatrix;
// Uninitialized, 5x5 row-major dynamic matrix
DynamicMatrix<int,rowMajor> A( 5, 5 );
// Default initialized, 5x5 row-major Hermitian dynamic matrix

\endcode
// \n \section adaptors_hermitian_matrices_arithmetic_operations Arithmetic Operations
// <hr>
//
// A HermitianMatrix can be used within all numerical operations in any way any other dense or
// sparse matrix can be used. It can also be combined with any other dense or sparse vector or
// matrix. The following code example gives an impression of the use of HermitianMatrix within

\code
using blaze::HermitianMatrix;
using blaze::DynamicMatrix;
using blaze::HybridMatrix;
using blaze::StaticMatrix;
using blaze::CompressedMatrix;
using blaze::rowMajor;
using blaze::columnMajor;
typedef complex<float> cplx;
DynamicMatrix<cplx,rowMajor> A( 3, 3 );
CompressedMatrix<cplx,rowMajor> B( 3, 3 );
HermitianMatrix< DynamicMatrix<cplx,rowMajor> > C( 3 );

HermitianMatrix< HybridMatrix<cplx,3UL,3UL,rowMajor> > E;
HermitianMatrix< StaticMatrix<cplx,3UL,3UL,columnMajor> > F;
E = A + B; // Matrix addition and assignment to a row-major Hermitian matrix
F = C - D; // Matrix subtraction and assignment to a column-major Hermitian matrix
F = A * D; // Matrix multiplication between a dense and a sparse matrix
C *= 2.0; // In-place scaling of matrix C
E = 2.0 * B; // Scaling of matrix B
F = C * 2.0; // Scaling of matrix C
E += A - B; // Addition assignment
F -= C + D; // Subtraction assignment
F *= A * D; // Multiplication assignment
\endcode
// \n \section adaptors_hermitian_matrices_performance Performance Considerations
// <hr>
//
// When the Hermitian property of a matrix is known beforehands using the HermitianMatrix adaptor
// instead of a general matrix can be a considerable performance advantage. This is particularly
// true in case the Hermitian matrix is also symmetric (i.e. has built-in element types). The
// \b Blaze library tries to exploit the properties of Hermitian (symmetric) matrices whenever
// possible. However, there are also situations when using a Hermitian matrix introduces some
// overhead. The following examples demonstrate several situations where Hermitian matrices can
// positively or negatively impact performance.
//
// \n \subsection adaptors_hermitian_matrices_matrix_matrix_multiplication Positive Impact: Matrix/Matrix Multiplication
//
// When multiplying two matrices, at least one of which is symmetric, \b Blaze can exploit the fact
// that \f$ A = A^T \f$ and choose the fastest and most suited combination of storage orders for the
// multiplication. The following example demonstrates this by means of a dense matrix/sparse matrix
// multiplication:
\code
using blaze::DynamicMatrix;
using blaze::HermitianMatrix;
using blaze::rowMajor;
using blaze::columnMajor;
HermitianMatrix< DynamicMatrix<double,rowMajor> > A; // Both Hermitian and symmetric
HermitianMatrix< CompressedMatrix<double,columnMajor> > B; // Both Hermitian and symmetric
DynamicMatrix<double,columnMajor> C;
// ... Resizing and initialization
C = A * B;
\endcode
// Intuitively, the chosen combination of a row-major and a column-major matrix is the most suited
// for maximum performance. However, \b Blaze evaluates the multiplication as
\code
C = A * trans( B );
\endcode
// which significantly increases the performance since in contrast to the original formulation the
// optimized form can be vectorized. Therefore, in the context of matrix multiplications, using a
// symmetric matrix is obviously an advantage.
//
// \n \subsection adaptors_hermitian_matrices_matrix_vector_multiplication Positive Impact: Matrix/Vector Multiplication
//
// A similar optimization is possible in case of matrix/vector multiplications:
\code
using blaze::DynamicMatrix;
using blaze::DynamicVector;
using blaze::CompressedVector;
using blaze::HermitianMatrix;
using blaze::rowMajor;
using blaze::columnVector;
HermitianMatrix< DynamicMatrix<double,rowMajor> > A; // Hermitian and symmetric
CompressedVector<double,columnVector> x;
DynamicVector<double,columnVector> y;
// ... Resizing and initialization
y = A * x;
\endcode
// In this example it is not intuitively apparent that using a row-major matrix is not the best
// possible choice in terms of performance since the computation cannot be vectorized. Choosing
// a column-major matrix instead, however, would enable a vectorized computation. Therefore
// \b Blaze exploits the fact that \c A is symmetric, selects the best suited storage order and
// evaluates the multiplication as
\code
y = trans( A ) * x;
\endcode
// which also significantly increases the performance.
//
// \n \subsection adaptors_hermitian_matrices_views Positive Impact: Row/Column Views on Column/Row-Major Matrices
//
// Another example is the optimization of a row view on a column-major symmetric matrix:
\code
using blaze::DynamicMatrix;
using blaze::HermitianMatrix;
using blaze::Row;
using blaze::rowMajor;
using blaze::columnMajor;
typedef HermitianMatrix< DynamicMatrix<double,columnMajor> > DynamicHermitian;
DynamicHermitian A( 10UL ); // Both Hermitian and symmetric
Row<DynamicHermitian> row5 = row( A, 5UL );
\endcode
// Usually, a row view on a column-major matrix results in a considerable performance decrease in
// comparison to a row view on a row-major matrix due to the non-contiguous storage of the matrix
// elements. However, in case of symmetric matrices, \b Blaze instead uses the according column of
// the matrix, which provides the same performance as if the matrix would be row-major. Note that
// this also works for column views on row-major matrices, where \b Blaze can use the according
// row instead of a column in order to provide maximum performance.
//
// \n \subsection adaptors_hermitian_matrices_assignment Negative Impact: Assignment of a General Matrix
//
// In contrast to using a Hermitian matrix on the right-hand side of an assignment (i.e. for read
// access), which introduces absolutely no performance penalty, using a Hermitian matrix on the
// left-hand side of an assignment (i.e. for write access) may introduce additional overhead when
// it is assigned a general matrix, which is not Hermitian at compile time:
\code
using blaze::DynamicMatrix;
using blaze::HermitianMatrix;
HermitianMatrix< DynamicMatrix< complex<double> > > A, C;
DynamicMatrix<double> B;
B = A; // Only read-access to the Hermitian matrix; no performance penalty
C = A; // Assignment of a Hermitian matrix to another Hermitian matrix; no runtime overhead
C = B; // Assignment of a general matrix to a Hermitian matrix; some runtime overhead
\endcode
// When assigning a general, potentially not Hermitian matrix to a Hermitian matrix it is necessary
// to check whether the matrix is Hermitian at runtime in order to guarantee the Hermitian property
// of the Hermitian matrix. In case it turns out to be Hermitian, it is assigned as efficiently as
// possible, if it is not, an exception is thrown. In order to prevent this runtime overhead it is
// therefore generally advisable to assign Hermitian matrices to other Hermitian matrices.\n
// In this context it is especially noteworthy that in contrast to additions and subtractions the
// multiplication of two Hermitian matrices does not necessarily result in another Hermitian matrix:
\code
HermitianMatrix< DynamicMatrix<double> > A, B, C;
C = A + B; // Results in a Hermitian matrix; no runtime overhead
C = A - B; // Results in a Hermitian matrix; no runtime overhead
C = A * B; // Is not guaranteed to result in a Hermitian matrix; some runtime overhead
\endcode

// 3x3 row-major diagonal dynamic matrix with default initialized lower and upper matrix
DiagonalMatrix< DynamicMatrix<int,rowMajor> > D( 3 );
\endcode
// \n \subsection adaptors_triangular_matrices_storage Dense Triangular Matrices Store All Elements!
//
// All dense triangular matrices store all \f$ N \times N \f$ elements, including the immutable
// elements in the lower or upper part, respectively. Therefore dense triangular matrices don't
// provide any kind of memory reduction! There are two main reasons for this: First, storing also
// the zero elements guarantees maximum performance for many algorithms that perform vectorized
// operations on the triangular matrices, which is especially true for small dense matrices.
// Second, conceptually all triangular adaptors merely restrict the interface to the matrix type
// \c MT and do not change the data layout or the underlying matrix type.
//
// This property matters most for diagonal matrices. In order to achieve the perfect combination
// of performance and memory consumption for a diagonal matrix it is recommended to use dense
// matrices for small diagonal matrices and sparse matrices for large diagonal matrices:
\code
// Recommendation 1: use dense matrices for small diagonal matrices
typedef blaze::DiagonalMatrix< blaze::StaticMatrix<float,3UL,3UL> > SmallDiagonalMatrix;
// Recommendation 2: use sparse matrices for large diagonal matrices
typedef blaze::DiagonalMatrix< blaze::CompressedMatrix<float> > LargeDiagonalMatrix;
\endcode
// \n \subsection adaptors_triangular_matrices_scaling Unitriangular Matrices Cannot Be Scaled!
//
// Since the diagonal elements of a unitriangular matrix have a fixed value of 1 it is not possible
// to self-scale such a matrix:
\code
using blaze::DynamicMatrix;
using blaze::UniLowerMatrix;
UniLowerMatrix< DynamicMatrix<int> > A( 4 );
A *= 2; // Compilation error; Scale operation is not available on an unilower matrix
A /= 2; // Compilation error; Scale operation is not available on an unilower matrix
A.scale( 2 ); // Compilation error; Scale function is not available on an unilower matrix
A = A * 2; // Throws an exception; Invalid assignment of non-unilower matrix
A = A / 2; // Throws an exception; Invalid assignment of non-unilower matrix
\endcode

//
// A lower and upper triangular matrix can participate in numerical operations in any way any other
// dense or sparse matrix can participate. It can also be combined with any other dense or sparse
// vector or matrix. The following code example gives an impression of the use of blaze::LowerMatrix
// and blaze::UpperMatrix within arithmetic operations:
\code
using blaze::LowerMatrix;
using blaze::DynamicMatrix;
using blaze::HybridMatrix;
using blaze::StaticMatrix;
using blaze::CompressedMatrix;
using blaze::rowMajor;
using blaze::columnMajor;
DynamicMatrix<double,rowMajor> A( 3, 3 );
CompressedMatrix<double,rowMajor> B( 3, 3 );
LowerMatrix< DynamicMatrix<double,rowMajor> > C( 3 );
UpperMatrix< CompressedMatrix<double,rowMajor> > D( 3 );
LowerMatrix< HybridMatrix<float,3UL,3UL,rowMajor> > E;
UpperMatrix< StaticMatrix<float,3UL,3UL,columnMajor> > F;
E = A + B; // Matrix addition and assignment to a row-major lower matrix
F = C - D; // Matrix subtraction and assignment to a column-major upper matrix
F = A * D; // Matrix multiplication between a dense and a sparse matrix
C *= 2.0; // In-place scaling of matrix C
E = 2.0 * B; // Scaling of matrix B
F = C * 2.0; // Scaling of matrix C
E += A - B; // Addition assignment
F -= C + D; // Subtraction assignment
F *= A * D; // Multiplication assignment
\endcode
// Note that diagonal, unitriangular and strictly triangular matrix types can be used in the same
// way, but may pose some additional restrictions (see the according class documentations).
//
//
// \n \section adaptors_triangular_matrices_block_matrices Triangular Block Matrices
// <hr>
//
// It is also possible to use triangular block matrices:
\code
using blaze::CompressedMatrix;
using blaze::DynamicMatrix;
using blaze::StaticMatrix;
using blaze::LowerMatrix;
using blaze::UpperMatrix;
// Definition of a 5x5 lower block matrix based on DynamicMatrix
LowerMatrix< DynamicMatrix< StaticMatrix<int,3UL,3UL> > > A( 5 );
// Definition of a 7x7 upper block matrix based on CompressedMatrix
UpperMatrix< CompressedMatrix< StaticMatrix<int,3UL,3UL> > > B( 7 );
\endcode
// Also in this case the triangular matrix invariant is enforced, i.e. it is not possible to
// manipulate elements in the upper part (lower triangular matrix) or the lower part (upper
// triangular matrix) of the matrix:
\code
const StaticMatrix<int,3UL,3UL> C{ { 1, -4, 5 },
{ 6, 8, -3 },
{ 2, -1, 2 } };
A(2,4)(1,1) = -5; // Invalid manipulation of upper matrix element; Results in an exception
B.insert( 4, 2, C ); // Invalid insertion of the elements (4,2); Results in an exception
\endcode
// Note that unitriangular matrices are restricted to numeric element types and therefore cannot
// be used for block matrices:
\code
using blaze::CompressedMatrix;
using blaze::DynamicMatrix;
using blaze::StaticMatrix;
using blaze::UniLowerMatrix;
using blaze::UniUpperMatrix;
// Compilation error: lower unitriangular matrices are restricted to numeric element types
UniLowerMatrix< DynamicMatrix< StaticMatrix<int,3UL,3UL> > > A( 5 );
// Compilation error: upper unitriangular matrices are restricted to numeric element types
UniUpperMatrix< CompressedMatrix< StaticMatrix<int,3UL,3UL> > > B( 7 );
\endcode

// \n \section adaptors_triangular_matrices_performance Performance Considerations
// <hr>
//
// The \b Blaze library tries to exploit the properties of lower and upper triangular matrices
// whenever and wherever possible. Therefore using triangular matrices instead of a general
// matrices can result in a considerable performance improvement. However, there are also
// situations when using a triangular matrix introduces some overhead. The following examples
// demonstrate several common situations where triangular matrices can positively or negatively
// impact performance.
//
// \n \subsection adaptors_triangular_matrices_matrix_matrix_multiplication Positive Impact: Matrix/Matrix Multiplication
//
// When multiplying two matrices, at least one of which is triangular, \b Blaze can exploit the
// fact that either the lower or upper part of the matrix contains only default elements and
// restrict the algorithm to the non-zero elements. The following example demonstrates this by
// means of a dense matrix/dense matrix multiplication with lower triangular matrices:
\code
using blaze::DynamicMatrix;
using blaze::LowerMatrix;
using blaze::rowMajor;
using blaze::columnMajor;
LowerMatrix< DynamicMatrix<double,rowMajor> > A;
LowerMatrix< DynamicMatrix<double,columnMajor> > B;
DynamicMatrix<double,columnMajor> C;
// ... Resizing and initialization
C = A * B;
\endcode
// In comparison to a general matrix multiplication, the performance advantage is significant,
// especially for large matrices. Therefore is it highly recommended to use the blaze::LowerMatrix
// and blaze::UpperMatrix adaptors when a matrix is known to be lower or upper triangular,
// respectively. Note however that the performance advantage is most pronounced for dense matrices
// and much less so for sparse matrices.
//
// \n \subsection adaptors_triangular_matrices_matrix_vector_multiplication Positive Impact: Matrix/Vector Multiplication
//
// A similar performance improvement can be gained when using a triangular matrix in a matrix/vector
// multiplication:
\code
using blaze::DynamicMatrix;
using blaze::DynamicVector;
using blaze::rowMajor;
using blaze::columnVector;
LowerMatrix< DynamicMatrix<double,rowMajor> > A;
DynamicVector<double,columnVector> x, y;
// ... Resizing and initialization
y = A * x;
\endcode
// In this example, \b Blaze also exploits the structure of the matrix and approx. halves the
// runtime of the multiplication. Also in case of matrix/vector multiplications the performance
// improvement is most pronounced for dense matrices and much less so for sparse matrices.
//
// \n \subsection adaptors_triangular_matrices_assignment Negative Impact: Assignment of a General Matrix
//
// In contrast to using a triangular matrix on the right-hand side of an assignment (i.e. for
// read access), which introduces absolutely no performance penalty, using a triangular matrix
// on the left-hand side of an assignment (i.e. for write access) may introduce additional
// overhead when it is assigned a general matrix, which is not triangular at compile time:
\code
using blaze::DynamicMatrix;
using blaze::LowerMatrix;
LowerMatrix< DynamicMatrix<double> > A, C;
DynamicMatrix<double> B;
B = A; // Only read-access to the lower matrix; no performance penalty
C = A; // Assignment of a lower matrix to another lower matrix; no runtime overhead
C = B; // Assignment of a general matrix to a lower matrix; some runtime overhead
\endcode
// When assigning a general (potentially not lower triangular) matrix to a lower matrix or a
// general (potentially not upper triangular) matrix to an upper matrix it is necessary to check
// whether the matrix is lower or upper at runtime in order to guarantee the triangular property
// of the matrix. In case it turns out to be lower or upper, respectively, it is assigned as
// efficiently as possible, if it is not, an exception is thrown. In order to prevent this runtime
// overhead it is therefore generally advisable to assign lower or upper triangular matrices to
// other lower or upper triangular matrices.\n
// In this context it is especially noteworthy that the addition, subtraction, and multiplication
// of two triangular matrices of the same structure always results in another triangular matrix:
\code
LowerMatrix< DynamicMatrix<double> > A, B, C;
C = A + B; // Results in a lower matrix; no runtime overhead
C = A - B; // Results in a lower matrix; no runtime overhead
C = A * B; // Results in a lower matrix; no runtime overhead
\endcode
\code
UpperMatrix< DynamicMatrix<double> > A, B, C;
C = A + B; // Results in a upper matrix; no runtime overhead
C = A - B; // Results in a upper matrix; no runtime overhead
C = A * B; // Results in a upper matrix; no runtime overhead
\endcode

// Subvectors provide views on a specific part of a dense or sparse vector. As such, subvectors
// act as a reference to a specific range within a vector. This reference is valid and can be
// used in every way any other dense or sparse vector can be used as long as the vector containing

// vector are immediately visible in the subvector.
//
//
// \n \section views_subvectors_class The Subvector Class Template
// <hr>
//
// The blaze::Subvector class template represents a view on a specific subvector of a dense or
// sparse vector primitive. It can be included via the header file
\code
#include <blaze/math/Subvector.h>
\endcode
// The type of the vector is specified via two template parameters:
\code
template< typename VT, bool AF >
class Subvector;
\endcode
// - \c VT: specifies the type of the vector primitive. Subvector can be used with every vector
// primitive or view, but does not work with any vector expression type.
// - \c AF: the alignment flag specifies whether the subvector is aligned (blaze::aligned) or
// unaligned (blaze::unaligned). The default value is blaze::unaligned.
//
//
// \n \section views_subvectors_setup Setup of Subvectors
// <hr>
//
// A view on a dense or sparse subvector can be created very conveniently via the \c subvector()
// function. This view can be treated as any other vector, i.e. it can be assigned to, it can
// be copied from, and it can be used in arithmetic operations. A subvector created from a row
// vector can be used as any other row vector, a subvector created from a column vector can be
// used as any other column vector. The view can also be used on both sides of an assignment:
// The subvector can either be used as an alias to grant write access to a specific subvector
// of a vector primitive on the left-hand side of an assignment or to grant read-access to a
// specific subvector of a vector primitive or expression on the right-hand side of an assignment.
// The following example demonstrates this in detail:
\code
typedef blaze::DynamicVector<double,blaze::rowVector> DenseVectorType;
typedef blaze::CompressedVector<int,blaze::rowVector> SparseVectorType;
DenseVectorType d1, d2;
SparseVectorType s1, s2;
// ... Resizing and initialization
// Creating a view on the first ten elements of the dense vector d1
blaze::Subvector<DenseVectorType> dsv = subvector( d1, 0UL, 10UL );
// Creating a view on the second ten elements of the sparse vector s1
blaze::Subvector<SparseVectorType> ssv = subvector( s1, 10UL, 10UL );
// Creating a view on the addition of d2 and s2
dsv = subvector( d2 + s2, 5UL, 10UL );
// Creating a view on the multiplication of d2 and s2
ssv = subvector( d2 * s2, 2UL, 10UL );
\endcode
// The \c subvector() function can be used on any dense or sparse vector, including expressions,
// as demonstrated in the example. Note however that a blaze::Subvector can only be instantiated
// with a dense or sparse vector primitive, i.e. with types that can be written, and not with an
// expression type.
//
//
// \n \section views_subvectors_common_operations Common Operations
// <hr>
//
// A subvector view can be used like any other dense or sparse vector. For instance, the current
// number of elements can be obtained via the \c size() function, the current capacity via the
// \c capacity() function, and the number of non-zero elements via the \c nonZeros() function.
// However, since subvectors are references to a specific range of a vector, several operations
// are not possible on views, such as resizing and swapping. The following example shows this by
// means of a dense subvector view:
\code
typedef blaze::DynamicVector<int,blaze::rowVector> VectorType;
typedef blaze::Subvector<VectorType> SubvectorType;
VectorType v( 42UL );
// ... Resizing and initialization
// Creating a view on the range [5..15] of vector v
SubvectorType sv = subvector( v, 5UL, 10UL );
sv.size(); // Returns the number of elements in the subvector
sv.capacity(); // Returns the capacity of the subvector
sv.nonZeros(); // Returns the number of non-zero elements contained in the subvector
sv.resize( 84UL ); // Compilation error: Cannot resize a subvector of a vector
SubvectorType sv2 = subvector( v, 15UL, 10UL );
swap( sv, sv2 ); // Compilation error: Swap operation not allowed
\endcode
// \n \section views_subvectors_element_access Element Access
// <hr>
//
// The elements of a subvector can be directly accessed via the subscript operator:
\code
typedef blaze::DynamicVector<double,blaze::rowVector> VectorType;
VectorType v;

blaze::Subvector<VectorType> sv = subvector( v, 4UL, 8UL );

sv[1] = 2.0;
\endcode
// The numbering of the subvector elements is
\f[\left(\begin{array}{*{5}{c}}
0 & 1 & 2 & \cdots & N-1 \\
\end{array}\right),\f]
// where N is the specified size of the subvector. Alternatively, the elements of a subvector can
// be traversed via iterators. Just as with vectors, in case of non-const subvectors, \c begin()
// and \c end() return an Iterator, which allows a manipulation of the non-zero values, in case
// of constant subvectors a ConstIterator is returned:

typedef blaze::DynamicVector<int,blaze::rowVector> VectorType;
typedef blaze::Subvector<VectorType> SubvectorType;
VectorType v( 256UL );
// ... Resizing and initialization
// Creating a reference to a specific subvector of the dense vector v

// \n \section views_aligned_subvectors Aligned Subvectors
// <hr>
//
// Usually subvectors can be defined anywhere within a vector. They may start at any position and
// may have an arbitrary size (only restricted by the size of the underlying vector). However, in
// contrast to vectors themselves, which are always properly aligned in memory and therefore can
// provide maximum performance, this means that subvectors in general have to be considered to be
// unaligned. This can be made explicit by the blaze::unaligned flag:
\code
using blaze::unaligned;
typedef blaze::DynamicVector<double,blaze::rowVector> DenseVectorType;
DenseVectorType x;
// ... Resizing and initialization
// Identical creations of an unaligned subvector in the range [8..23]
blaze::Subvector<DenseVectorType> sv1 = subvector ( x, 8UL, 16UL );
blaze::Subvector<DenseVectorType> sv2 = subvector<unaligned>( x, 8UL, 16UL );
blaze::Subvector<DenseVectorType,unaligned> sv3 = subvector ( x, 8UL, 16UL );
blaze::Subvector<DenseVectorType,unaligned> sv4 = subvector<unaligned>( x, 8UL, 16UL );
\endcode
// All of these calls to the \c subvector() function are identical. Whether the alignment flag is
// explicitly specified or not, it always returns an unaligned subvector. Whereas this may provide
// full flexibility in the creation of subvectors, this might result in performance disadvantages
// in comparison to vector primitives (even in case the specified subvector could be aligned).
// Whereas vector primitives are guaranteed to be properly aligned and therefore provide maximum
// performance in all operations, a general view on a vector might not be properly aligned. This
// may cause a performance penalty on some platforms and/or for some operations.
//
// However, it is also possible to create aligned subvectors. Aligned subvectors are identical to
// unaligned subvectors in all aspects, except that they may pose additional alignment restrictions
// and therefore have less flexibility during creation, but don't suffer from performance penalties
// and provide the same performance as the underlying vector. Aligned subvectors are created by
// explicitly specifying the blaze::aligned flag:
\code
using blaze::aligned;
// Creating an aligned dense subvector in the range [8..23]
blaze::Subvector<DenseVectorType,aligned> sv = subvector<aligned>( x, 8UL, 16UL );
\endcode
// The alignment restrictions refer to system dependent address restrictions for the used element
// type and the available vectorization mode (SSE, AVX, ...). In order to be properly aligned the
// first element of the subvector must be aligned. The following source code gives some examples
// for a double precision dynamic vector, assuming that AVX is available, which packs 4 \c double
// values into a SIMD vector:
\code
using blaze::aligned;
using blaze::columnVector;
typedef blaze::DynamicVector<double,columnVector> VectorType;
typedef blaze::Subvector<VectorType,aligned> SubvectorType;
VectorType d( 17UL );
// ... Resizing and initialization
// OK: Starts at the beginning, i.e. the first element is aligned
SubvectorType dsv1 = subvector<aligned>( d, 0UL, 13UL );
// OK: Start index is a multiple of 4, i.e. the first element is aligned
SubvectorType dsv2 = subvector<aligned>( d, 4UL, 7UL );
// OK: The start index is a multiple of 4 and the subvector includes the last element
SubvectorType dsv3 = subvector<aligned>( d, 8UL, 9UL );
// Error: Start index is not a multiple of 4, i.e. the first element is not aligned
SubvectorType dsv4 = subvector<aligned>( d, 5UL, 8UL );
\endcode
// Note that the discussed alignment restrictions are only valid for aligned dense subvectors.
// In contrast, aligned sparse subvectors at this time don't pose any additional restrictions.
// Therefore aligned and unaligned sparse subvectors are truly fully identical. Still, in case
// the blaze::aligned flag is specified during setup, an aligned subvector is created:
\code
using blaze::aligned;
typedef blaze::CompressedVector<double,blaze::rowVector> SparseVectorType;
SparseVectorType x;
// ... Resizing and initialization
// Creating an aligned subvector in the range [8..23]
blaze::Subvector<SparseVectorType,aligned> sv = subvector<aligned>( x, 8UL, 16UL );

// Usually submatrices can be defined anywhere within a matrix. They may start at any position and
// may have an arbitrary extension (only restricted by the extension of the underlying matrix).
// However, in contrast to matrices themselves, which are always properly aligned in memory and
// therefore can provide maximum performance, this means that submatrices in general have to be
// considered to be unaligned. This can be made explicit by the blaze::unaligned flag:
\code
using blaze::unaligned;
typedef blaze::DynamicMatrix<double,blaze::rowMajor> DenseMatrixType;
DenseMatrixType A;
// ... Resizing and initialization
// Identical creations of an unaligned submatrix of size 8x8, starting in row 0 and column 0

blaze::Submatrix<DenseMatrixType,unaligned> sm3 = submatrix ( A, 0UL, 0UL, 8UL, 8UL );
blaze::Submatrix<DenseMatrixType,unaligned> sm4 = submatrix<unaligned>( A, 0UL, 0UL, 8UL, 8UL );
\endcode
// All of these calls to the \c submatrix() function are identical. Whether the alignment flag is
// explicitly specified or not, it always returns an unaligned submatrix. Whereas this may provide
// full flexibility in the creation of submatrices, this might result in performance disadvantages
// in comparison to matrix primitives (even in case the specified submatrix could be aligned).
// Whereas matrix primitives are guaranteed to be properly aligned and therefore provide maximum
// performance in all operations, a general view on a matrix might not be properly aligned. This
// may cause a performance penalty on some platforms and/or for some operations.
//
// However, it is also possible to create aligned submatrices. Aligned submatrices are identical to
// unaligned submatrices in all aspects, except that they may pose additional alignment restrictions
// and therefore have less flexibility during creation, but don't suffer from performance penalties
// and provide the same performance as the underlying matrix. Aligned submatrices are created by
// explicitly specifying the blaze::aligned flag:
\code
using blaze::aligned;
// Creating an aligned submatrix of size 8x8, starting in row 0 and column 0
blaze::Submatrix<DenseMatrixType,aligned> sv = submatrix<aligned>( A, 0UL, 0UL, 8UL, 8UL );
\endcode
// The alignment restrictions refer to system dependent address restrictions for the used element
// type and the available vectorization mode (SSE, AVX, ...). In order to be properly aligned the
// first element of each row/column of the submatrix must be aligned. The following source code
// gives some examples for a double precision row-major dynamic matrix, assuming that padding is
// enabled and that AVX is available, which packs 4 \c double values into a SIMD vector:
\code
using blaze::aligned;
using blaze::rowMajor;
typedef blaze::DynamicMatrix<double,rowMajor> MatrixType;
typedef blaze::Submatrix<MatrixType,aligned> SubmatrixType;
MatrixType D( 13UL, 17UL );
// ... Resizing and initialization
// OK: Starts at position (0,0), i.e. the first element of each row is aligned (due to padding)
SubmatrixType dsm1 = submatrix<aligned>( D, 0UL, 0UL, 7UL, 11UL );
// OK: First column is a multiple of 4, i.e. the first element of each row is aligned (due to padding)
SubmatrixType dsm2 = submatrix<aligned>( D, 3UL, 12UL, 8UL, 16UL );
// OK: First column is a multiple of 4 and the submatrix includes the last row and column
SubmatrixType dsm3 = submatrix<aligned>( D, 4UL, 0UL, 9UL, 17UL );
// Error: First column is not a multiple of 4, i.e. the first element is not aligned
SubmatrixType dsm4 = submatrix<aligned>( D, 2UL, 3UL, 12UL, 12UL );
\endcode
// Note that the discussed alignment restrictions are only valid for aligned dense submatrices.
// In contrast, aligned sparse submatrices at this time don't pose any additional restrictions.
// Therefore aligned and unaligned sparse submatrices are truly fully identical. Still, in case
// the blaze::aligned flag is specified during setup, an aligned submatrix is created:
\code
using blaze::aligned;
typedef blaze::CompressedMatrix<double,blaze::rowMajor> SparseMatrixType;

/*!\page views_columns Columns
//
// \tableofcontents
//
//
// Just as rows provide a view on a specific row of a matrix, columns provide views on a specific
// column of a dense or sparse matrix. As such, columns act as a reference to a specific column.
// This reference is valid an can be used in every way any other column vector can be used as long
// as the matrix containing the column is not resized or entirely destroyed. Changes made to the
// elements (e.g. modifying values, inserting or erasing elements) are immediately visible in the
// matrix and changes made via the matrix are immediately visible in the column.
//
//
// \n \section views_columns_class The Column Class Template
// <hr>
//
// The blaze::Column class template represents a reference to a specific column of a dense or
// sparse matrix primitive. It can be included via the header file
\code
#include <blaze/math/Column.h>
\endcode
// The type of the matrix is specified via template parameter:
\code
template< typename MT >
class Column;
\endcode
// \c MT specifies the type of the matrix primitive. Column can be used with every matrix
// primitive, but does not work with any matrix expression type.
//
//
// \n \section views_colums_setup Setup of Columns
// <hr>
//
// Similar to the setup of a row, a reference to a dense or sparse column can be created very
// conveniently via the \c column() function. This reference can be treated as any other column
// vector, i.e. it can be assigned to, copied from, and be used in arithmetic operations. The
// column can either be used as an alias to grant write access to a specific column of a matrix
// primitive on the left-hand side of an assignment or to grant read-access to a specific column
// of a matrix primitive or expression on the right-hand side of an assignment. The following
// two examples demonstrate this for dense and sparse matrices:
\code
typedef blaze::DynamicVector<double,columnVector> DenseVectorType;
typedef blaze::CompressedVector<double,columnVector> SparseVectorType;
typedef blaze::DynamicMatrix<double,columnMajor> DenseMatrixType;
typedef blaze::CompressedMatrix<double,columnMajor> SparseMatrixType;
DenseVectorType x;
SparseVectorType y;
DenseMatrixType A, B;
SparseMatrixType C, D;
// ... Resizing and initialization
// Setting the 1st column of matrix A to x
blaze::Column<DenseMatrixType> col1 = column( A, 1UL );
col1 = x;
// Setting the 4th column of matrix B to y
column( B, 4UL ) = y;
// Setting x to the 2nd column of the result of the matrix multiplication
x = column( A * B, 2UL );
// Setting y to the 2nd column of the result of the sparse matrix multiplication
y = column( C * D, 2UL );
\endcode
// The \c column() function can be used on any dense or sparse matrix, including expressions, as
// illustrated by the source code example. However, columns cannot be instantiated for expression
// types, but only for matrix primitives, respectively, i.e. for matrix types that offer write
// access.
//
//
// \n \section views_columns_common_operations Common Operations
// <hr>
//
// A column view can be used like any other column vector. For instance, the current number of
// elements can be obtained via the \c size() function, the current capacity via the \c capacity()
// function, and the number of non-zero elements via the \c nonZeros() function. However, since
// columns are references to specific columns of a matrix, several operations are not possible on
// views, such as resizing and swapping. The following example shows this by means of a dense
// column view:
\code
typedef blaze::DynamicMatrix<int,columnMajor> MatrixType;
typedef blaze::Column<MatrixType> ColumnType;
MatrixType A( 42UL, 42UL );
// ... Resizing and initialization
// Creating a reference to the 2nd column of matrix A

col2.nonZeros(); // Returns the number of non-zero elements contained in the column
col2.resize( 84UL ); // Compilation error: Cannot resize a single column of a matrix

// where N is the number of rows of the referenced matrix. Alternatively, the elements of
// a column can be traversed via iterators. Just as with vectors, in case of non-const columns,
// \c begin() and \c end() return an Iterator, which allows a manipulation of the non-zero
// value, in case of a constant column a ConstIterator is returned:

// In addition to the provided operations on vectors and matrices it is possible to define custom

\code
blaze::DynamicMatrix<double> A, B;
B = forEach( A, []( double d ){ return std::sqrt( d ); } );
\endcode
// This example demonstrates the most convenient way of defining a custom operation by passing a
// lambda to the \c forEach() function. The lambda is executed on each single element of a dense
// vector or matrix or each non-zero element of a sparse vector or matrix.
//
// Alternatively, it is possible to pass a custom functor:
\code
struct Sqrt
{
double operator()( double a ) const
{
return std::sqrt( a );
}
};
B = forEach( A, Sqrt() );
\endcode
// In order for the functor to work in a call to \c forEach() it must define a function call
// operator, which accepts arguments of the type of the according vector or matrix elements.
//
// Although the operation is automatically parallelized depending on the size of the vector or
// matrix, no automatic vectorization is possible. In order to enable vectorization, a \c load()
// function can be added to the functor, which handles the vectorized computation. Depending on
// the data type this function is passed one of the following \b Blaze SIMD data types:

//
// All SIMD types provide the \c value data member for a direct access to the underlying intrinsic
// data element. In the following example, this intrinsic element is passed to the AVX function

{
return std::sqrt( a );
}
simd_double_t load( simd_double_t a ) const
{
return _mm256_sqrt_pd( a.value );
}
};
\endcode
// In this example, whenever vectorization is generally applicable, the \c load() function is
// called instead of the function call operator for as long as the number of remaining elements
// is larger-or-equal to the width of the packed SIMD type. In all other cases (which also
// includes peel-off and remainder loops) the scalar operation is used.
//
// Please note that this example has two drawbacks: First, it will only compile in case the
// intrinsic \c _mm256_sqrt_pd() function is available (i.e. when AVX is active). Second, the
// availability of AVX is not taken into account. The first drawback can be alleviated by making
// the \c load() function a function template. The second drawback can be dealt with by adding a
// \c simdEnabled() function template to the functor:
\code
struct Sqrt
{
double operator()( double a ) const
{
return std::sqrt( a );
}
template< typename T >
T load( T a ) const
{
return _mm256_sqrt_pd( a.value );
}
template< typename T >
static constexpr bool simdEnabled() {
#if defined(__AVX__)
return true;
#else
return false;
#endif
}
};
\endcode
// The \c simdEnabled() function must be a \c static, \c constexpr function and must return whether
// or not vectorization is available for the given data type \c T. In case the function returns
// \c true, the \c load() function is used for a vectorized evaluation, in case the function
// returns \c false, \c load() is not called.
//
// Note that this is a simplified example that is only working when used for dense vectors and
// matrices with double precision floating point elements. The following code shows the complete
// implementation of the according functor that is used within the \b Blaze library. The \b Blaze
// \c Sqrt functor is working for all data types that are providing a square root operation:
\code
namespace blaze {
struct Sqrt
{

{
return sqrt( a );
}
template< typename T >
static constexpr bool simdEnabled() { return HasSIMDSqrt<T>::value; }
template< typename T >
BLAZE_ALWAYS_INLINE auto load( const T& a ) const
{
BLAZE_CONSTRAINT_MUST_BE_SIMD_TYPE( T );
return sqrt( a );
}
};
} // namespace blaze

//
// \n \section openmp_setup OpenMP Setup
// <hr>
//
// To enable the OpenMP-based parallelization, all that needs to be done is to explicitly specify
// the use of OpenMP on the command line:
\code
-fopenmp // GNU C++ compiler
-openmp // Intel C++ compiler
/openmp // Visual Studio
\endcode
// This simple action will cause the \b Blaze library to automatically try to run all operations
// in parallel with the specified number of threads.
//
// As common for OpenMP, the number of threads can be specified either via an environment variable
\code
export OMP_NUM_THREADS=4 // Unix systems
set OMP_NUM_THREADS=4 // Windows systems
\endcode
// or via an explicit call to the \c omp_set_num_threads() function:
\code
omp_set_num_threads( 4 );
\endcode
// Alternatively, the number of threads can also be specified via the \c setNumThreads() function
// provided by the \b Blaze library:
\code
blaze::setNumThreads( 4 );
\endcode
// Please note that the \b Blaze library does not limit the available number of threads. Therefore
// it is in YOUR responsibility to choose an appropriate number of threads. The best performance,
// though, can be expected if the specified number of threads matches the available number of
// cores.
//
// In order to query the number of threads used for the parallelization of operations, the
// \c getNumThreads() function can be used:
\code
const size_t threads = blaze::getNumThreads();
\endcode
// In the context of OpenMP, the function returns the maximum number of threads OpenMP will use
// within a parallel region and is therefore equivalent to the \c omp_get_max_threads() function.
//
//
// \n \section openmp_configuration OpenMP Configuration
// <hr>
//
// Note that \b Blaze is not unconditionally running an operation in parallel. In case \b Blaze
// deems the parallel execution as counterproductive for the overall performance, the operation
// is executed serially. One of the main reasons for not executing an operation in parallel is
// the size of the operands. For instance, a vector addition is only executed in parallel if the
// size of both vector operands exceeds a certain threshold. Otherwise, the performance could
// seriously decrease due to the overhead caused by the thread setup. However, in order to be
// able to adjust the \b Blaze library to a specific system, it is possible to configure these
// thresholds manually. All shared memory thresholds are contained within the configuration file
// <tt>./blaze/config/Thresholds.h</tt>.
//
// Please note that these thresholds are highly sensitiv to the used system architecture and
// the shared memory parallelization technique (see also \ref cpp_threads_parallelization and
// \ref boost_threads_parallelization). Therefore the default values cannot guarantee maximum
// performance for all possible situations and configurations. They merely provide a reasonable
// standard for the current CPU generation.
//
//
// \n \section openmp_first_touch First Touch Policy
// <hr>
//
// So far the \b Blaze library does not (yet) automatically initialize dynamic memory according
// to the first touch principle. Consider for instance the following vector triad example:
\code
using blaze::columnVector;
const size_t N( 1000000UL );
blaze::DynamicVector<double,columnVector> a( N ), b( N ), c( N ), d( N );
// Initialization of the vectors b, c, and d
for( size_t i=0UL; i<N; ++i ) {
b[i] = rand<double>();
c[i] = rand<double>();
d[i] = rand<double>();
}
// Performing a vector triad
a = b + c * d;
\endcode
// If this code, which is prototypical for many OpenMP applications that have not been optimized
// for ccNUMA architectures, is run across several locality domains (LD), it will not scale
// beyond the maximum performance achievable on a single LD if the working set does not fit into
// the cache. This is because the initialization loop is executed by a single thread, writing to
// \c b, \c c, and \c d for the first time. Hence, all memory pages belonging to those arrays will
// be mapped into a single LD.
//
// As mentioned above, this problem can be solved by performing vector initialization in parallel:
\code
// ...
// Initialization of the vectors b, c, and d
#pragma omp parallel for
for( size_t i=0UL; i<N; ++i ) {
b[i] = rand<double>();
c[i] = rand<double>();
d[i] = rand<double>();
}
// ...
\endcode
// This simple modification makes a huge difference on ccNUMA in memory-bound situations (as for
// instance in all BLAS level 1 operations and partially BLAS level 2 operations). Therefore, in
// order to achieve the maximum possible performance, it is imperative to initialize the memory
// according to the later use of the data structures.
//
//
// \n \section openmp_limitations Limitations of the OpenMP Parallelization
// <hr>
//
// There are a few important limitations to the current \b Blaze OpenMP parallelization. The first
// one involves the explicit use of an OpenMP parallel region (see \ref openmp_parallel), the
// other one the OpenMP \c sections directive (see \ref openmp_sections).
//
//
// \n \subsection openmp_parallel The Parallel Directive
//
// In OpenMP threads are explicitly spawned via the an OpenMP parallel directive:
\code
// Serial region, executed by a single thread
#pragma omp parallel
{
// Parallel region, executed by the specified number of threads
}
// Serial region, executed by a single thread
\endcode
// Conceptually, the specified number of threads (see \ref openmp_setup) is created every time a
// parallel directive is encountered. Therefore, from a performance point of view, it seems to be
// beneficial to use a single OpenMP parallel directive for several operations:
\code
blaze::DynamicVector<double> x, y1, y2;
blaze::DynamicMatrix<double> A, B;
#pragma omp parallel
{
y1 = A * x;
y2 = B * x;
}
\endcode
// Unfortunately, this optimization approach is not allowed within the \b Blaze library. More
// explicitly, it is not allowed to put an operation into a parallel region. The reason is that
// the entire code contained within a parallel region is executed by all threads. Although this
// appears to just comprise the contained computations, a computation (or more specifically the
// assignment of an expression to a vector or matrix) can contain additional logic that must not
// be handled by multiple threads (as for instance memory allocations, setup of temporaries, etc.).
// Therefore it is not possible to manually start a parallel region for several operations, but
// \b Blaze will spawn threads automatically, depending on the specifics of the operation at hand
// and the given operands.
//
// \n \subsection openmp_sections The Sections Directive
//
// OpenMP provides several work-sharing construct to distribute work among threads. One of these
// constructs is the \c sections directive:
\code
blaze::DynamicVector<double> x, y1, y2;
blaze::DynamicMatrix<double> A, B;
// ... Resizing and initialization
#pragma omp sections
{
#pragma omp section
y1 = A * x;
#pragma omp section
y2 = B * x;
}
\endcode
// In this example, two threads are used to compute two distinct matrix/vector multiplications
// concurrently. Thereby each of the \c sections is executed by exactly one thread.
//
// Unfortunately \b Blaze does not support concurrent parallel computations and therefore this
// approach does not work with any of the \b Blaze parallelization techniques. All techniques
// (including the C++11 and Boost thread parallelizations; see \ref cpp_threads_parallelization
// and \ref boost_threads_parallelization) are optimized for the parallel computation of an
// operation within a single thread of execution. This means that \b Blaze tries to use all
// available threads to compute the result of a single operation as efficiently as possible.
// Therefore, for this special case, it is advisable to disable all \b Blaze parallelizations
// and to let \b Blaze compute all operations within a \c sections directive in serial. This can
// be done by either completely disabling the \b Blaze parallelization (see \ref serial_execution)
// or by selectively serializing all operations within a \c sections directive via the \c serial()
// function:
\code
blaze::DynamicVector<double> x, y1, y2;
blaze::DynamicMatrix<double> A, B;
// ... Resizing and initialization
#pragma omp sections
{
#pragma omp section
y1 = serial( A * x );
#pragma omp section
y2 = serial( B * x );
}
\endcode
// Please note that the use of the \c BLAZE_SERIAL_SECTION (see also \ref serial_execution) does
// NOT work in this context!

// purpose, the \b Blaze library offers three possible options: the serialization of a single
// expression via the \c serial() function, the serialization of a block of expressions via the
// \c BLAZE_SERIAL_SECTION, and the general deactivation of the parallel execution.
//
//
// \n \section serial_execution_serial_expression Option 1: Serialization of a Single Expression
// <hr>
//
// The first option is the serialization of a specific operation via the \c serial() function:
\code
blaze::DynamicMatrix<double> A, B, C;
// ... Resizing and initialization
C = serial( A + B );
\endcode
// \c serial() enforces the serial evaluation of the enclosed expression. It can be used on any
// kind of dense or sparse vector or matrix expression.
//
//
// \n \section serial_execution_serial_section Option 2: Serialization of Multiple Expressions
// <hr>
//
// The second option is the temporary and local enforcement of a serial execution via the
// \c BLAZE_SERIAL_SECTION:
\code
using blaze::rowMajor;
using blaze::columnVector;
blaze::DynamicMatrix<double,rowMajor> A;
blaze::DynamicVector<double,columnVector> b, c, d, x, y, z;
// ... Resizing and initialization
// Parallel execution
// If possible and beneficial for performance the following operation is executed in parallel.
x = A * b;
// Serial execution
// All operations executed within the serial section are guaranteed to be executed in
// serial (even if a parallel execution would be possible and/or beneficial).
BLAZE_SERIAL_SECTION
{
y = A * c;
z = A * d;
}
// Parallel execution continued
// ...
\endcode
// Within the scope of the \c BLAZE_SERIAL_SECTION, all operations are guaranteed to run in serial.
// Outside the scope of the serial section, all operations are run in parallel (if beneficial for
// the performance).
//
// Note that the \c BLAZE_SERIAL_SECTION must only be used within a single thread of execution.
// The use of the serial section within several concurrent threads will result undefined behavior!
//
//
// \n \section serial_execution_deactivate_parallelism Option 3: Deactivation of Parallel Execution
// <hr>
//
// The third option is the general deactivation of the parallel execution (even in case OpenMP is
// enabled on the command line). This can be achieved via the \c BLAZE_USE_SHARED_MEMORY_PARALLELIZATION
// switch in the <tt>./blaze/config/SMP.h</tt> configuration file:
\code
#define BLAZE_USE_SHARED_MEMORY_PARALLELIZATION 1
\endcode
// In case the \c BLAZE_USE_SHARED_MEMORY_PARALLELIZATION switch is set to 0, the shared memory
// parallelization is deactivated altogether.

//**Configuration Files****************************************************************************
/*!\page configuration_files Configuration Files
//
// \tableofcontents
//
//
// Sometimes it might necessary to adapt \b Blaze to specific requirements. For this purpose
// \b Blaze provides several configuration files in the <tt>./blaze/config/</tt> subdirectory,
// which provide ample opportunity to customize internal settings, behavior, and thresholds.
// This chapter explains the most important of these configuration files.
//
//
// \n \section transpose_flag Default Vector Storage
// <hr>
//
// The \b Blaze default is that all vectors are created as column vectors (if not specified
// explicitly):
\code
blaze::StaticVector<double,3UL> x; // Creates a 3-dimensional static column vector
\endcode
// The header file <tt>./blaze/config/TransposeFlag.h</tt> allows the configuration of the default
// vector storage (i.e. the default transpose flag of the vectors). Via the \c defaultTransposeFlag
// value the default transpose flag for all vector of the \b Blaze library can be specified:
\code
constexpr bool defaultTransposeFlag = columnVector;
\endcode
// Valid settings for the \c defaultTransposeFlag are blaze::rowVector and blaze::columnVector.
//
//
// \n \section storage_order Default Matrix Storage
// <hr>
//
// Matrices are by default created as row-major matrices:
\code
blaze::StaticMatrix<double,3UL,3UL> A; // Creates a 3x3 row-major matrix
\endcode
// The header file <tt>./blaze/config/StorageOrder.h</tt> allows the configuration of the default
// matrix storage order. Via the \c defaultStorageOrder value the default storage order for all
// matrices of the \b Blaze library can be specified.
\code
constexpr bool defaultStorageOrder = rowMajor;
\endcode
// Valid settings for the \c defaultStorageOrder are blaze::rowMajor and blaze::columnMajor.
//
//
// \n \section blas_mode BLAS Mode
// <hr>
//
// In order to achieve maximum performance for multiplications with dense matrices, \b Blaze can
// be configured to use a BLAS library. Via the following compilation switch in the configuration
// file <tt>./blaze/config/BLAS.h</tt> BLAS can be enabled:
\code
#define BLAZE_BLAS_MODE 1
\endcode
// In case the selected BLAS library provides parallel execution, the \c BLAZE_BLAS_IS_PARALLEL
// switch should be activated to prevent \b Blaze from parallelizing on its own:
\code
#define BLAZE_BLAS_IS_PARALLEL 1
\endcode
// In case no BLAS library is available, \b Blaze will still work and will not be reduced in
// functionality, but performance may be limited.
//
//
// \n \section cache_size Cache Size
// <hr>
//
// The optimization of several \b Blaze compute kernels depends on the cache size of the target
// architecture. By default, \b Blaze assumes a cache size of 3 MiByte. However, for optimal
// speed the exact cache size of the system should be provided via the \c cacheSize value in the
// <tt>./blaze/config/CacheSize.h</tt> configuration file:
\code
constexpr size_t cacheSize = 3145728UL;
\endcode
// \n \section vectorization Vectorization
// <hr>
//
// In order to achieve maximum performance and to exploit the compute power of a target platform
// the \b Blaze library attempts to vectorize all linear algebra operations by SSE, AVX, and/or
// MIC intrinsics, depending on which instruction set is available. However, it is possible to
// disable the vectorization entirely by the compile time switch in the configuration file
// <tt>./blaze/config/Vectorization.h</tt>:
\code
#define BLAZE_USE_VECTORIZATION 1
\endcode
// In case the switch is set to 1, vectorization is enabled and the \b Blaze library is allowed
// to use intrinsics to speed up computations. In case the switch is set to 0, vectorization is
// disabled entirely and the \b Blaze library chooses default, non-vectorized functionality for
// the operations. Note that deactivating the vectorization may pose a severe performance
// limitation for a large number of operations!
//
//
// \n \section thresholds Thresholds
// <hr>
//
// For many computations \b Blaze distinguishes between small and large vectors and matrices.
// This separation is especially important for the parallel execution of computations, since
// the use of several threads only pays off for sufficiently large vectors and matrices.
// Additionally, it also enables \b Blaze to select kernels that are optimized for a specific
// size.
//
// In order to distinguish between small and large data structures \b Blaze provides several
// thresholds that can be adapted to the characteristics of the target platform. For instance,
// the \c DMATDVECMULT_THRESHOLD specifies the threshold between the application of the custom
// \b Blaze kernels for small dense matrix/dense vector multiplications and the BLAS kernels
// for large multiplications. All thresholds, including the thresholds for the OpenMP- and
// thread-based parallelization, are contained within the configuration file
// <tt>./blaze/config/Thresholds.h</tt>.
//
//
// \n \section padding Padding
// <hr>
//
// By default the \b Blaze library uses padding for all dense vectors and matrices in order to
// achieve maximum performance in all operations. Due to padding, the proper alignment of data
// elements can be guaranteed and the need for remainder loops is minimized. However, on the
// downside padding introduces an additional memory overhead, which can be large depending on
// the used data type.
//
// The configuration file <tt>./blaze/config/Optimizations.h</tt> provides a compile time switch
// that can be used to (de-)activate padding:
\code
constexpr bool usePadding = true;
\endcode
// If \c usePadding is set to \c true padding is enabled for all dense vectors and matrices, if
// it is set to \c false padding is disabled. Note however that disabling padding can considerably
// reduce the performance of all dense vector and matrix operations!
//
//
// \n \section streaming Streaming (Non-Temporal Stores)
// <hr>
//
// For vectors and matrices that don't fit into the cache anymore non-temporal stores can provide
// a significant performance advantage of about 20%. However, this advantage is only in effect in
// case the memory bandwidth of the target architecture is maxed out. If the target architecture's
// memory bandwidth cannot be exhausted the use of non-temporal stores can decrease performance
// instead of increasing it.
//
// The configuration file <tt>./blaze/config/Optimizations.h</tt> provides a compile time switch
// that can be used to (de-)activate streaming:
\code
constexpr bool useStreaming = true;
\endcode
// If \c useStreaming is set to \c true streaming is enabled, if it is set to \c false streaming
// is disabled. It is recommended to consult the target architecture's white papers to decide
// whether streaming is beneficial or hurtful for performance.
//

/*!\page block_vectors_and_matrices Block Vectors and Matrices
//
// \tableofcontents
//
//
// \n \section block_vectors_and_matrices_general General Concepts
// <hr>
//
// In addition to fundamental element types, the \b Blaze library supports vectors and matrices
// with non-fundamental element type. For instance, it is possible to define block matrices by
// using a matrix type as the element type:
\code
using blaze::DynamicMatrix;
using blaze::DynamicVector;
using blaze::rowMajor;
using blaze::columnVector;
DynamicMatrix< DynamicMatrix<double,rowMajor>, rowMajor > A;
DynamicVector< DynamicVector<double,columnVector >, columnVector > x, y;
// ... Resizing and initialization
y = A * x;
\endcode
// The matrix/vector multiplication in this example runs fully parallel and uses vectorization
// for every inner matrix/vector multiplication and vector addition.
//
//
// \n \section block_vectors_and_matrices_pitfalls Pitfalls
// <hr>
//
// The only thing to keep in mind when using non-fundamental element types is that all operations
// between the elements have to be well defined. More specifically, the size of vector and matrix
// elements has to match. The attempt to combine two non-matching elements results in either a
// compilation error (in case of statically sized elements) or an exception (for dynamically sized
// elements):
\code
DynamicVector< StaticVector<int,2UL> > a;
DynamicVector< StaticVector<int,3UL> > b;
DynamicVector< DynamicVector<int> > c( a + b ); // Compilation error: element size doesn't match
\endcode
// Therefore please don't forget that dynamically sized elements (e.g. \c blaze::DynamicVector,
// \c blaze::HybridVector, \c blaze::DynamicMatrix, \c blaze::HybridMatrix, ...) need to be sized
// accordingly upfront.
//
//
// \n \section block_vectors_and_matrices_example Example
// <hr>
//
// The following example demonstrates a complete multiplication between a statically sized block
// matrix and block vector:
\code
// ( ( 1 1 ) ( 2 2 ) ) ( ( 1 ) ) ( ( 10 ) )
// ( ( 1 1 ) ( 2 2 ) ) ( ( 1 ) ) ( ( 10 ) )

//**Custom Data Types******************************************************************************
/*!\page custom_data_types Custom Data Types
//
//
// The \b Blaze library tries hard to make the use of custom data types as convenient, easy and
// intuitive as possible. However, unfortunately it is not possible to meet the requirements of
// all possible data types. Thus it might be necessary to provide \b Blaze with some additional
// information about the data type. The following sections give an overview of the necessary steps
// to enable the use of the hypothetical custom data type \c custom::double_t for vector and
// matrix operations. For example:
\code
blaze::DynamicVector<custom::double_t> a, b, c;
// ... Resizing and initialization
c = a + b;
\endcode
// The \b Blaze library assumes that the \c custom::double_t data type provides \c operator+()
// for additions, \c operator-() for subtractions, \c operator*() for multiplications and
// \c operator/() for divisions. If any of these functions is missing it is necessary to implement
// the operator to perform the according operation. For this example we assume that the custom
// data type provides the four following functions instead of operators:
\code
namespace custom {
double_t add ( const double_t& a, const double_t b );
double_t sub ( const double_t& a, const double_t b );
double_t mult( const double_t& a, const double_t b );
double_t div ( const double_t& a, const double_t b );
} // namespace custom
\endcode
// The following implementations will satisfy the requirements of the \b Blaze library:
\code
inline custom::double_t operator+( const custom::double_t& a, const custom::double_t& b )
{
return add( a, b );
}
inline custom::double_t operator-( const custom::double_t& a, const custom::double_t& b )
{
return sub( a, b );
}
inline custom::double_t operator*( const custom::double_t& a, const custom::double_t& b )
{
return mult( a, b );
}
inline custom::double_t operator/( const custom::double_t& a, const custom::double_t& b )
{
return div( a, b );
}
\endcode
// \b Blaze will use all the information provided with these functions (for instance the return
// type) to properly handle the operations. In the rare case that the return type cannot be
// automatically determined from the operator it might be additionally necessary to provide a
// specialization of the following four \b Blaze class templates:
\code
namespace blaze {
template<>
struct AddTrait<custom::double_t,custom::double_t> {
typedef custom::double_t Type;
};
template<>
struct SubTrait<custom::double_t,custom::double_t> {
typedef custom::double_t Type;
};
template<>
struct MultTrait<custom::double_t,custom::double_t> {
typedef custom::double_t Type;
};
template<>
struct DivTrait<custom::double_t,custom::double_t> {
typedef custom::double_t Type;
};
} // namespace blaze
\endcode
// The same steps are necessary if several custom data types need to be combined (as for instance
// \c custom::double_t and \c custom::float_t). Note that in this case both permutations need to
// be taken into account:
\code
custom::double_t operator+( const custom::double_t& a, const custom::float_t& b );
custom::double_t operator+( const custom::float_t& a, const custom::double_t& b );
// ...
\endcode
// Please note that only built-in data types apply for vectorization and thus custom data types
// cannot achieve maximum performance!

//**Customization of the Error Reporting Mechanism*************************************************
/*!\page error_reporting_customization Customization of the Error Reporting Mechanism
//
// \tableofcontents
//
//
// \n \section error_reporting_background Background
// <hr>
//
// The default way of \b Blaze to report errors of any kind is to throw a standard exception.
// However, although in general this approach works well, in certain environments and under
// special circumstances exceptions may not be the mechanism of choice and a different error
// reporting mechanism may be desirable. For this reason, \b Blaze provides several macros,
// which enable the customization of the error reporting mechanism. Via these macros it is
// possible to replace the standard exceptions by some other exception type or a completely
// different approach to report errors.
//
//
// \n \section error_reporting_general_customization Customization of the Reporting Mechanism
// <hr>
//
// In some cases it might be necessary to adapt the entire error reporting mechanism and to
// replace it by some other means to signal failure. The primary macro for this purpose is the
// \c BLAZE_THROW macro:
\code
#define BLAZE_THROW( EXCEPTION ) \
throw EXCEPTION
\endcode
// This macro represents the default mechanism of the \b Blaze library to report errors of any
// kind. In order to customize the error reporing mechanism all that needs to be done is to
// define the macro prior to including any \b Blaze header file. This will cause the \b Blaze
// specific mechanism to be overridden. The following example demonstrates this by replacing
// exceptions by a call to a \c log() function and a direct call to abort:
\code
#define BLAZE_THROW( EXCEPTION ) \
log( "..." ); \
abort()
#include <blaze/Blaze.h>
\endcode
// Doing this will trigger a call to \c log() and an abort instead of throwing an exception
// whenever an error (such as an invalid argument) is detected.
//
// \note It is possible to execute several statements instead of executing a single statement to
// throw an exception. Also note that it is recommended to define the macro such that a subsequent
// semicolon is required!
//
// \warning This macro is provided with the intention to assist in adapting \b Blaze to special
// conditions and environments. However, the customization of the error reporting mechanism via
// this macro can have a significant effect on the library. Thus be advised to use the macro
// with due care!
//
//
// \n \section error_reporting_exception_customization Customization of the Type of Exceptions
// <hr>
//
// In addition to the customization of the entire error reporting mechanism it is also possible
// to customize the type of exceptions being thrown. This can be achieved by customizing any
// number of the following macros:
\code
#define BLAZE_THROW_BAD_ALLOC \
BLAZE_THROW( std::bad_alloc() )
#define BLAZE_THROW_LOGIC_ERROR( MESSAGE ) \
BLAZE_THROW( std::logic_error( MESSAGE ) )
#define BLAZE_THROW_INVALID_ARGUMENT( MESSAGE ) \
BLAZE_THROW( std::invalid_argument( MESSAGE ) )
#define BLAZE_THROW_LENGTH_ERROR( MESSAGE ) \
BLAZE_THROW( std::length_error( MESSAGE ) )
#define BLAZE_THROW_OUT_OF_RANGE( MESSAGE ) \
BLAZE_THROW( std::out_of_range( MESSAGE ) )
#define BLAZE_THROW_RUNTIME_ERROR( MESSAGE ) \
BLAZE_THROW( std::runtime_error( MESSAGE ) )
\endcode
// In order to customize the type of exception the according macro has to be defined prior to
// including any \b Blaze header file. This will override the \b Blaze default behavior. The
// following example demonstrates this by replacing \c std::invalid_argument by a custom
// exception type:
\code
class InvalidArgument
{
public:
InvalidArgument();
explicit InvalidArgument( const std::string& message );
// ...
};
#define BLAZE_THROW_INVALID_ARGUMENT( MESSAGE ) \
BLAZE_THROW( InvalidArgument( MESSAGE ) )
#include <blaze/Blaze.h>
\endcode
// By manually defining the macro, an \c InvalidArgument exception is thrown instead of a
// \c std::invalid_argument exception. Note that it is recommended to define the macro such
// that a subsequent semicolon is required!
//
// \warning These macros are provided with the intention to assist in adapting \b Blaze to
// special conditions and environments. However, the customization of the type of an exception
// via this macro may have an effect on the library. Thus be advised to use the macro with due
// care!
//
//
// \n \section error_reporting_special_errors Customization of Special Errors
// <hr>
//
// Last but not least it is possible to customize the error reporting for special kinds of errors.
// This can be achieved by customizing any number of the following macros:
\code
#define BLAZE_THROW_DIVISION_BY_ZERO( MESSAGE ) \
BLAZE_THROW_RUNTIME_ERROR( MESSAGE )
#define BLAZE_THROW_LAPACK_ERROR( MESSAGE ) \
BLAZE_THROW_RUNTIME_ERROR( MESSAGE )
\endcode
// As explained in the previous sections, in order to customize the handling of special errors
// the according macro has to be defined prior to including any \b Blaze header file. This will
// override the \b Blaze default behavior.
//

//*************************************************************************************************
//**Intra-Statement Optimization*******************************************************************
/*!\page intra_statement_optimization Intra-Statement Optimization
//
// One of the prime features of the \b Blaze library is the automatic intra-statement optimization.
// In order to optimize the overall performance of every single statement \b Blaze attempts to
// rearrange the operands based on their types. For instance, the following addition of dense and
// sparse vectors
\code
blaze::DynamicVector<double> d1, d2, d3;
blaze::CompressedVector<double> s1;
// ... Resizing and initialization
d3 = d1 + s1 + d2;
\endcode
// is automatically rearranged and evaluated as
\code
// ...
d3 = d1 + d2 + s1; // <- Note that s1 and d2 have been rearranged
\endcode
// This order of operands is highly favorable for the overall performance since the addition of
// the two dense vectors \c d1 and \c d2 can be handled much more efficiently in a vectorized
// fashion.
//
// This intra-statement optimization can have a tremendous effect on the performance of a statement.
// Consider for instance the following computation:
\code
blaze::DynamicMatrix<double> A, B;
blaze::DynamicVector<double> x, y;
// ... Resizing and initialization
y = A * B * x;
\endcode
// Since multiplications are evaluated from left to right, this statement would result in a
// matrix/matrix multiplication, followed by a matrix/vector multiplication. However, if the
// right subexpression is evaluated first, the performance can be dramatically improved since the
// matrix/matrix multiplication can be avoided in favor of a second matrix/vector multiplication.
// The \b Blaze library exploits this by automatically restructuring the expression such that the
// right multiplication is evaluated first:
\code
// ...
y = A * ( B * x );
\endcode
// Note however that although this intra-statement optimization may result in a measurable or
// even significant performance improvement, this behavior may be undesirable for several reasons,
// for instance because of numerical stability. Therefore, in case the order of evaluation matters,
// the best solution is to be explicit and to separate a statement into several statements:
\code
blaze::DynamicVector<double> d1, d2, d3;
blaze::CompressedVector<double> s1;
// ... Resizing and initialization
d3 = d1 + s1; // Compute the dense vector/sparse vector addition first ...
d3 += d2; // ... and afterwards add the second dense vector
\endcode
\code
// ...
blaze::DynamicMatrix<double> A, B, C;
blaze::DynamicVector<double> x, y;
// ... Resizing and initialization
C = A * B; // Compute the left-hand side matrix-matrix multiplication first ...
y = C * x; // ... before the right-hand side matrix-vector multiplication
\endcode
// Alternatively, it is also possible to use the \c eval() function to fix the order of evaluation:
\code
blaze::DynamicVector<double> d1, d2, d3;
blaze::CompressedVector<double> s1;
// ... Resizing and initialization
d3 = d1 + eval( s1 + d2 );
\endcode
\code
blaze::DynamicMatrix<double> A, B;
blaze::DynamicVector<double> x, y;
// ... Resizing and initialization
y = eval( A * B ) * x;
\endcode

//
// The ProgramEvaluator runs the cost functions contained in each residual block
// and stores the result into a jacobian. The particular type of jacobian is
// abstracted out using two template parameters:
//
// - An "EvaluatePreparer" that is responsible for creating the array with
// pointers to the jacobian blocks where the cost function evaluates to.
// - A "JacobianWriter" that is responsible for storing the resulting
// jacobian blocks in the passed sparse matrix.
//
// This abstraction affords an efficient evaluator implementation while still
// supporting writing to multiple sparse matrix formats. For example, when the
// ProgramEvaluator is parameterized for writing to block sparse matrices, the
// residual jacobians are written directly into their final position in the
// block sparse matrix by the user's CostFunction; there is no copying.
//
// The evaluation is threaded with OpenMP or TBB.
//
// The EvaluatePreparer and JacobianWriter interfaces are as follows:
//
// class EvaluatePreparer {
// // Prepare the jacobians array for use as the destination of a call to
// // a cost function's evaluate method.
// void Prepare(const ResidualBlock* residual_block,
// int residual_block_index,
// SparseMatrix* jacobian,
// double** jacobians);
// }
//
// class JacobianWriter {
// // Create a jacobian that this writer can write. Same as
// // Evaluator::CreateJacobian.
// SparseMatrix* CreateJacobian() const;
//
// // Create num_threads evaluate preparers. Caller owns result which must
// // be freed with delete[]. Resulting preparers are valid while *this is.
// EvaluatePreparer* CreateEvaluatePreparers(int num_threads);
//
// // Write the block jacobians from a residual block evaluation to the
// // larger sparse jacobian.
// void Write(int residual_id,
// int residual_offset,
// double** jacobians,
// SparseMatrix* jacobian);
// }
//
// Note: The ProgramEvaluator is not thread safe, since internally it maintains
// some per-thread scratch space.

//
// The ProgramEvaluator runs the cost functions contained in each residual block
// and stores the result into a jacobian. The particular type of jacobian is
// abstracted out using two template parameters:
//
// - An "EvaluatePreparer" that is responsible for creating the array with
// pointers to the jacobian blocks where the cost function evaluates to.
// - A "JacobianWriter" that is responsible for storing the resulting
// jacobian blocks in the passed sparse matrix.
//
// This abstraction affords an efficient evaluator implementation while still
// supporting writing to multiple sparse matrix formats. For example, when the
// ProgramEvaluator is parameterized for writing to block sparse matrices, the
// residual jacobians are written directly into their final position in the
// block sparse matrix by the user's CostFunction; there is no copying.
//
// The evaluation is threaded with OpenMP.
//
// The EvaluatePreparer and JacobianWriter interfaces are as follows:
//
// class EvaluatePreparer {
// // Prepare the jacobians array for use as the destination of a call to
// // a cost function's evaluate method.
// void Prepare(const ResidualBlock* residual_block,
// int residual_block_index,
// SparseMatrix* jacobian,
// double** jacobians);
// }
//
// class JacobianWriter {
// // Create a jacobian that this writer can write. Same as
// // Evaluator::CreateJacobian.
// SparseMatrix* CreateJacobian() const;
//
// // Create num_threads evaluate preparers. Caller owns result which must
// // be freed with delete[]. Resulting preparers are valid while *this is.
// EvaluatePreparer* CreateEvaluatePreparers(int num_threads);
//
// // Write the block jacobians from a residual block evaluation to the
// // larger sparse jacobian.
// void Write(int residual_id,
// int residual_offset,
// double** jacobians,
// SparseMatrix* jacobian);
// }
//
// Note: The ProgramEvaluator is not thread safe, since internally it maintains
// some per-thread scratch space.

/* miniz.c v1.15 - public domain deflate/inflate, zlib-subset, ZIP
reading/writing/appending, PNG writing
See "unlicense" statement at the end of this file.
Rich Geldreich <richgel99@gmail.com>, last updated Oct. 13, 2013
Implements RFC 1950: http://www.ietf.org/rfc/rfc1950.txt and RFC 1951:
http://www.ietf.org/rfc/rfc1951.txt
Most API's defined in miniz.c are optional. For example, to disable the
archive related functions just define
MINIZ_NO_ARCHIVE_APIS, or to get rid of all stdio usage define MINIZ_NO_STDIO
(see the list below for more macros).
* Change History
10/13/13 v1.15 r4 - Interim bugfix release while I work on the next major
release with Zip64 support (almost there!):
- Critical fix for the MZ_ZIP_FLAG_DO_NOT_SORT_CENTRAL_DIRECTORY bug
(thanks kahmyong.moon@hp.com) which could cause locate files to not find
files. This bug
would only have occured in earlier versions if you explicitly used this
flag, OR if you used mz_zip_extract_archive_file_to_heap() or
mz_zip_add_mem_to_archive_file_in_place()
(which used this flag). If you can't switch to v1.15 but want to fix
this bug, just remove the uses of this flag from both helper funcs (and of
course don't use the flag).
- Bugfix in mz_zip_reader_extract_to_mem_no_alloc() from kymoon when
pUser_read_buf is not NULL and compressed size is > uncompressed size
- Fixing mz_zip_reader_extract_*() funcs so they don't try to extract
compressed data from directory entries, to account for weird zipfiles which
contain zero-size compressed data on dir entries.
Hopefully this fix won't cause any issues on weird zip archives,
because it assumes the low 16-bits of zip external attributes are DOS
attributes (which I believe they always are in practice).
- Fixing mz_zip_reader_is_file_a_directory() so it doesn't check the
internal attributes, just the filename and external attributes
- mz_zip_reader_init_file() - missing MZ_FCLOSE() call if the seek failed
- Added cmake support for Linux builds which builds all the examples,
tested with clang v3.3 and gcc v4.6.
- Clang fix for tdefl_write_image_to_png_file_in_memory() from toffaletti
- Merged MZ_FORCEINLINE fix from hdeanclark
- Fix <time.h> include before config #ifdef, thanks emil.brink
- Added tdefl_write_image_to_png_file_in_memory_ex(): supports Y flipping
(super useful for OpenGL apps), and explicit control over the compression
level (so you can
set it to 1 for real-time compression).
- Merged in some compiler fixes from paulharris's github repro.
- Retested this build under Windows (VS 2010, including static analysis),
tcc 0.9.26, gcc v4.6 and clang v3.3.
- Added example6.c, which dumps an image of the mandelbrot set to a PNG
file.
- Modified example2 to help test the
MZ_ZIP_FLAG_DO_NOT_SORT_CENTRAL_DIRECTORY flag more.
- In r3: Bugfix to mz_zip_writer_add_file() found during merge: Fix
possible src file fclose() leak if alignment bytes+local header file write
faiiled
- In r4: Minor bugfix to mz_zip_writer_add_from_zip_reader():
Was pushing the wrong central dir header offset, appears harmless in this
release, but it became a problem in the zip64 branch
5/20/12 v1.14 - MinGW32/64 GCC 4.6.1 compiler fixes: added MZ_FORCEINLINE,
#include <time.h> (thanks fermtect).
5/19/12 v1.13 - From jason@cornsyrup.org and kelwert@mtu.edu - Fix
mz_crc32() so it doesn't compute the wrong CRC-32's when mz_ulong is 64-bit.
- Temporarily/locally slammed in "typedef unsigned long mz_ulong" and
re-ran a randomized regression test on ~500k files.
- Eliminated a bunch of warnings when compiling with GCC 32-bit/64.
- Ran all examples, miniz.c, and tinfl.c through MSVC 2008's /analyze
(static analysis) option and fixed all warnings (except for the silly
"Use of the comma-operator in a tested expression.." analysis warning,
which I purposely use to work around a MSVC compiler warning).
- Created 32-bit and 64-bit Codeblocks projects/workspace. Built and
tested Linux executables. The codeblocks workspace is compatible with
Linux+Win32/x64.
- Added miniz_tester solution/project, which is a useful little app
derived from LZHAM's tester app that I use as part of the regression test.
- Ran miniz.c and tinfl.c through another series of regression testing on
~500,000 files and archives.
- Modified example5.c so it purposely disables a bunch of high-level
functionality (MINIZ_NO_STDIO, etc.). (Thanks to corysama for the
MINIZ_NO_STDIO bug report.)
- Fix ftell() usage in examples so they exit with an error on files which
are too large (a limitation of the examples, not miniz itself).
4/12/12 v1.12 - More comments, added low-level example5.c, fixed a couple
minor level_and_flags issues in the archive API's.
level_and_flags can now be set to MZ_DEFAULT_COMPRESSION. Thanks to Bruce
Dawson <bruced@valvesoftware.com> for the feedback/bug report.
5/28/11 v1.11 - Added statement from unlicense.org
5/27/11 v1.10 - Substantial compressor optimizations:
- Level 1 is now ~4x faster than before. The L1 compressor's throughput
now varies between 70-110MB/sec. on a
- Core i7 (actual throughput varies depending on the type of data, and x64
vs. x86).
- Improved baseline L2-L9 compression perf. Also, greatly improved
compression perf. issues on some file types.
- Refactored the compression code for better readability and
maintainability.
- Added level 10 compression level (L10 has slightly better ratio than
level 9, but could have a potentially large
drop in throughput on some files).
5/15/11 v1.09 - Initial stable release.
* Low-level Deflate/Inflate implementation notes:
Compression: Use the "tdefl" API's. The compressor supports raw, static,
and dynamic blocks, lazy or
greedy parsing, match length filtering, RLE-only, and Huffman-only streams.
It performs and compresses
approximately as well as zlib.
Decompression: Use the "tinfl" API's. The entire decompressor is
implemented as a single function
coroutine: see tinfl_decompress(). It supports decompression into a 32KB
(or larger power of 2) wrapping buffer, or into a memory
block large enough to hold the entire file.
The low-level tdefl/tinfl API's do not make any use of dynamic memory
allocation.
* zlib-style API notes:
miniz.c implements a fairly large subset of zlib. There's enough
functionality present for it to be a drop-in
zlib replacement in many apps:
The z_stream struct, optional memory allocation callbacks
deflateInit/deflateInit2/deflate/deflateReset/deflateEnd/deflateBound
inflateInit/inflateInit2/inflate/inflateEnd
compress, compress2, compressBound, uncompress
CRC-32, Adler-32 - Using modern, minimal code size, CPU cache friendly
routines.
Supports raw deflate streams or standard zlib streams with adler-32
checking.
Limitations:
The callback API's are not implemented yet. No support for gzip headers or
zlib static dictionaries.
I've tried to closely emulate zlib's various flavors of stream flushing
and return status codes, but
there are no guarantees that miniz.c pulls this off perfectly.
* PNG writing: See the tdefl_write_image_to_png_file_in_memory() function,
originally written by
Alex Evans. Supports 1-4 bytes/pixel images.
* ZIP archive API notes:
The ZIP archive API's where designed with simplicity and efficiency in
mind, with just enough abstraction to
get the job done with minimal fuss. There are simple API's to retrieve file
information, read files from
existing archives, create new archives, append new files to existing
archives, or clone archive data from
one archive to another. It supports archives located in memory or the heap,
on disk (using stdio.h),
or you can specify custom file read/write callbacks.
- Archive reading: Just call this function to read a single file from a
disk archive:
void *mz_zip_extract_archive_file_to_heap(const char *pZip_filename, const
char *pArchive_name,
size_t *pSize, mz_uint zip_flags);
For more complex cases, use the "mz_zip_reader" functions. Upon opening an
archive, the entire central
directory is located and read as-is into memory, and subsequent file access
only occurs when reading individual files.
- Archives file scanning: The simple way is to use this function to scan a
loaded archive for a specific file:
int mz_zip_reader_locate_file(mz_zip_archive *pZip, const char *pName,
const char *pComment, mz_uint flags);
The locate operation can optionally check file comments too, which (as one
example) can be used to identify
multiple versions of the same file in an archive. This function uses a
simple linear search through the central
directory, so it's not very fast.
Alternately, you can iterate through all the files in an archive (using
mz_zip_reader_get_num_files()) and
retrieve detailed info on each file by calling mz_zip_reader_file_stat().
- Archive creation: Use the "mz_zip_writer" functions. The ZIP writer
immediately writes compressed file data
to disk and builds an exact image of the central directory in memory. The
central directory image is written
all at once at the end of the archive file when the archive is finalized.
The archive writer can optionally align each file's local header and file
data to any power of 2 alignment,
which can be useful when the archive will be read from optical media. Also,
the writer supports placing
arbitrary data blobs at the very beginning of ZIP archives. Archives
written using either feature are still
readable by any ZIP tool.
- Archive appending: The simple way to add a single file to an archive is
to call this function:
mz_bool mz_zip_add_mem_to_archive_file_in_place(const char *pZip_filename,
const char *pArchive_name,
const void *pBuf, size_t buf_size, const void *pComment, mz_uint16
comment_size, mz_uint level_and_flags);
The archive will be created if it doesn't already exist, otherwise it'll be
appended to.
Note the appending is done in-place and is not an atomic operation, so if
something goes wrong
during the operation it's possible the archive could be left without a
central directory (although the local
file headers and file data will be fine, so the archive will be
recoverable).
For more complex archive modification scenarios:
1. The safest way is to use a mz_zip_reader to read the existing archive,
cloning only those bits you want to
preserve into a new archive using using the
mz_zip_writer_add_from_zip_reader() function (which compiles the
compressed file data as-is). When you're done, delete the old archive and
rename the newly written archive, and
you're done. This is safe but requires a bunch of temporary disk space or
heap memory.
2. Or, you can convert an mz_zip_reader in-place to an mz_zip_writer using
mz_zip_writer_init_from_reader(),
append new files as needed, then finalize the archive which will write an
updated central directory to the
original archive. (This is basically what
mz_zip_add_mem_to_archive_file_in_place() does.) There's a
possibility that the archive's central directory could be lost with this
method if anything goes wrong, though.
- ZIP archive support limitations:
No zip64 or spanning support. Extraction functions can only handle
unencrypted, stored or deflated files.
Requires streams capable of seeking.
* This is a header file library, like stb_image.c. To get only a header file,
either cut and paste the
below header, or create miniz.h, #define MINIZ_HEADER_FILE_ONLY, and then
include miniz.c from it.
* Important: For best perf. be sure to customize the below macros for your
target platform:
#define MINIZ_USE_UNALIGNED_LOADS_AND_STORES 1
#define MINIZ_LITTLE_ENDIAN 1
#define MINIZ_HAS_64BIT_REGISTERS 1

% TransformImage() is a convenience method that behaves like ResizeImage() or
% CropImage() but accepts scaling and/or cropping information as a region
% geometry specification. If the operation fails, the original image handle
% is left as is.
%
% This should only be used for single images.
%
% This function destroys what it assumes to be a single image list.
% If the input image is part of a larger list, all other images in that list
% will be simply 'lost', not destroyed.
%
% Also if the crop generates a list of images only the first image is resized.
% And finally if the crop succeeds and the resize failed, you will get a
% cropped image, as well as a 'false' or 'failed' report.
%
% This function and should probably be deprecated in favor of direct calls
% to CropImageToTiles() or ResizeImage(), as appropriate.
%
% The format of the TransformImage method is:
%
% MagickBooleanType TransformImage(Image **image,const char *crop_geometry,
% const char *image_geometry,ExceptionInfo *exception)
%
% A description of each parameter follows:
%
% o image: the image The transformed image is returned as this parameter.
%
% o crop_geometry: A crop geometry string. This geometry defines a
% subregion of the image to crop.
%
% o image_geometry: An image geometry string. This geometry defines the
% final size of the image.
%
% o exception: return any errors or warnings in this structure.

// LAGraph_grread: read a matrix from a binary file.
// Contributed by Tim Davis, Texas A&M, based on the Galois graph reader
// file format.
// The file format consists of a header, with the following content:
// uint64_t version : TODO what is this?
// This value is returned to the caller, but is otherwise unused.
// uint64_t esize : the size of the edge weight, as sizeof (edgetype).
// For example, if the file contains edge weights of type int32_t,
// esize is sizeof (int32_t) == 4. The caller must specify the
// corresponding GrB_Type, and its size must match esize.
// uint64_t n : the number of node in the graph. The GrB_Matrix is
// n-by-n. Rectangular matrices are not supported by this format.
// uint64_t e : the number of edges in the graph
// This header is followed by a matrix in CSR format:
// Gp : an array of size ((n+1) * sizeof (uint64_t)) bytes, but Cp [0] = 0
// does not appear in the file. This section of the file is thus
// (n * sizeof (uint64_t)) bytes in length.
// Gj : an array of size (e * sizeof (int32_t)), containing the adjaceny
// lists. Note that the indices are 32 bit, not 64 bit, and thus
// this format is limited to graphs with n < 2^32.
// Gx : an array of size (e * esize), containing the edge weights.
// LAgraph_grread returns its status: GrB_SUCCESS if succesful,
// GrB_OUT_OF_MEMORY if out of memory, GrB_INVALID_VALUE if a file I/O error
// occurs or the edge size is not what was expected.

@ref kmeans.h implements a number of algorithm for **K-means
quantization**: Lloyd @cite{lloyd82least}, an accelerated version by
Elkan @cite{elkan03using}, and a large scale algorithm based on
Approximate Nearest Neighbors (ANN). All algorithms support @c float
or @c double data and can use the $l^1$ or the $l^2$ distance for
clustering. Furthermore, all algorithms can take advantage of multiple
CPU cores.
Please see @subpage kmeans-fundamentals for a technical description of
K-means and of the algorithms implemented here.
<!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->
@section kmeans-starting Getting started
<!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->
The goal of K-means is to partition a dataset into $K$
“compact” clusters. The following example demonstrates
using @ref kmeans.h in the C programming language to partition @c
numData @c float vectors into compute @c numCenters clusters using
Lloyd's algorithm:
@code
#include <vl/kmeans.h>
double energy ;
double * centers ;
// Use float data and the L2 distance for clustering
KMeans * kmeans = vl_kmeans_new (VLDistanceL2, VL_TYPE_FLOAT) ;
// Use Lloyd algorithm
vl_kmeans_set_algorithm (kmeans, VlKMeansLloyd) ;
// Initialize the cluster centers by randomly sampling the data
vl_kmeans_init_centers_with_rand_data (kmeans, data, dimension, numData, numCenters) ;
// Run at most 100 iterations of cluster refinement using Lloyd algorithm
vl_kmeans_set_max_num_iterations (kmeans, 100) ;
vl_kmeans_refine_centers (kmeans, data, numData) ;
// Obtain the energy of the solution
energy = vl_kmeans_get_energy(kmeans) ;
// Obtain the cluster centers
centers = vl_kmeans_get_centers(kmeans) ;
@endcode
Once the centers have been obtained, new data points can be assigned
to clusters by using the ::vl_kmeans_quantize function:
@code
vl_uint32 * assignments = vl_malloc(sizeof(vl_uint32) * numData) ;
float * distances = vl_malloc(sizeof(float) * numData) ;
vl_kmeans_quantize(kmeans, assignments, distances, data, numData) ;
@endcode
Alternatively, one can directly assign new pointers to the closest
centers, without bothering with a ::VlKMeans object.
There are several considerations that may impact the performance of
KMeans. First, since K-means is usually based local optimization
algorithm, the **initialization method** is important. The following
initialization methods are supported:
Method | Function | Description
---------------|-----------------------------------------|-----------------------------------------------
Random samples | ::vl_kmeans_init_centers_with_rand_data | Random data points
K-means++ | ::vl_kmeans_init_centers_plus_plus | Random selection biased towards diversity
Custom | ::vl_kmeans_set_centers | Choose centers (useful to run quantization only)
See @ref kmeans-init for further details. The initialization methods
use a randomized selection of the data points; the random number
generator init is controlled by ::vl_rand_init.
The second important choice is the **optimization algorithm**. The
following optimization algorithms are supported:
Algorithm | Symbol | See | Description
------------|------------------|-------------------|-----------------------------------------------
Lloyd | ::VlKMeansLloyd | @ref kmeans-lloyd | Alternate EM-style optimization
Elkan | ::VlKMeansElkan | @ref kmeans-elkan | A speedup using triangular inequalities
ANN | ::VlKMeansANN | @ref kmeans-ann | A speedup using approximated nearest neighbors
See the relative sections for further details. These algorithm are
iterative, and stop when either a **maximum number of iterations**
(::vl_kmeans_set_max_num_iterations) is reached, or when the energy
changes sufficiently slowly in one iteration (::vl_kmeans_set_min_energy_variation).
All the three algorithms support multithreaded computations. The number
of threads used is usually controlled globally by ::vl_set_num_threads.

<!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->
Given $n$ points $\bx_1,\dots,\bx_n \in \real^d$, the goal of K-means
is find $K$ `centers` $\bc_1,\dots,\bc_m \in \real^d$ and
`assignments` $q_1,\dots,q_n \in \{1,\dots,K\}$ of the points to the
centers such that the sum of distances
\[
E(\bc_1,\dots,\bc_k,q_1,\dots,q_n)
= \sum_{i=1}^n \|\bx_i - \bc_{q_i} \|_p^p
\]
is minimized. $K$-means is obtained for the case $p=2$ ($l^2$ norm),
because in this case the optimal centers are the means of the input
vectors assigned to them. Here the generalization $p=1$ ($l^1$ norm)
will also be considered.
Up to normalization, the K-means objective $E$ is also the average
reconstruction error if the original points are approximated with the
cluster centers. Thus K-means is used not only to group the input
points into cluster, but also to `quantize` their values.
K-means is widely used in computer vision, for example in the
construction of vocabularies of visual features (visual words). In
these applications the number $n$ of points to cluster and/or the
number $K$ of clusters is often large. Unfortunately, minimizing the
objective $E$ is in general a difficult combinatorial problem, so
locally optimal or approximated solutions are sought instead.
The basic K-means algorithm alternate between re-estimating the
centers and the assignments (@ref kmeans-lloyd). Combined with a good
initialization strategy (@ref kmeans-init) and, potentially, by
re-running the optimization from a number of randomized starting
states, this algorithm may attain satisfactory solutions in practice.
However, despite its simplicity, Lloyd's algorithm is often too slow.
A good replacement is Elkan's algorithm (@ref kmeans-elkan), which
uses the triangular inequality to cut down significantly the cost of
Lloyd's algorithm. Since this algorithm is otherwise equivalent, it
should often be preferred.
For very large problems (millions of point to clusters and hundreds,
thousands, or more clusters to find), even Elkan's algorithm is not
sufficiently fast. In these cases, one can resort to a variant of
Lloyd's algorithm that uses an approximated nearest neighbors routine
(@ref kmeans-ann).
<!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->
@section kmeans-init Initialization methods
<!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->
All the $K$-means algorithms considered here find locally optimal
solutions; as such the way they are initialized is important. @ref
kmeans.h supports the following initialization algorithms:
@par Random data samples
The simplest initialization method is to sample $K$ points at random
from the input data and use them as initial values for the cluster
centers.
@par K-means++
@cite{arthur07k-means} proposes a randomized initialization of the
centers which improves upon random selection. The first center $\bc_1$
is selected at random from the data points $\bx_1, \dots, \bx_n $ and
the distance from this center to all points $\|\bx_i - \bc_1\|_p^p$ is
computed. Then the second center $\bc_2$ is selected at random from
the data points with probability proportional to the distance. The
procedure is repeated to obtain the other centers by using the minimum
distance to the centers collected so far.
<!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->
@section kmeans-lloyd Lloyd's algorithm
<!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->
The most common K-means method is Lloyd's algorithm
@cite{lloyd82least}. This algorithm is based on the observation that,
while jointly optimizing clusters and assignment is difficult,
optimizing one given the other is easy. Lloyd's algorithm alternates
the steps:
1. **Quantization.** Each point $\bx_i$ is reassigned to the center
$\bc_{q_j}$ closer to it. This requires finding for each point the
closest among $K$ other points, which is potentially slow.
2. **Center estimation.** Each center $\bc_q$ is updated to minimize
its average distances to the points assigned to it. It is easy to
show that the best center is the mean or median of the points,
respectively if the $l^2$ or $l^1$ norm is considered.
A naive implementation of the assignment step requires $O(dnK)$
operations, where $d$ is the dimensionality of the data, $n$ the
number of data points, and $K$ the number of centers. Updating the
centers is much cheaper: $O(dn)$ operations suffice to compute the $K$
means and a slightly higher cost is required for the medians. Clearly,
the bottleneck is the assignment computation, and this is what the
other K-means algorithm try to improve.
During the iterations, it can happen that a cluster becomes empty. In
this case, K-means automatically **“restarts” the
cluster** center by selecting a training point at random.
<!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->
@section kmeans-elkan Elkan's algorithm
<!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->
Elkan's algorithm @cite{elkan03using} is a variation of Lloyd
alternate optimization algorithm (@ref kmeans-lloyd) that uses the
triangular inequality to avoid many distance calculations when
assigning points to clusters. While much faster than Lloyd, Elkan's
method uses storage proportional to the umber of clusters by data
points, which makes it unpractical for a very large number of
clusters.
The idea of this algorithm is that, if a center update does not move
them much, then most of the point-to-center computations can be
avoided when the point-to-center assignments are recomputed. To detect
which distances need evaluation, the triangular inequality is used to
lower and upper bound distances after a center update.
Elkan algorithms uses two key observations. First, one has
\[
\|\bx_i - \bc_{q_i}\|_p \leq \|\bc - \bc_{q_i}\|_p / 2
\quad\Rightarrow\quad
\|\bx_i - \bc_{q_i}\|_p \leq \|\bx_i - \bc\|_p.
\]
Thus if the distance between $\bx_i$ and its current center
$\bc_{q_i}$ is less than half the distance of the center $\bc_{q_i}$
to another center $\bc$, then $\bc$ can be skipped when the new
assignment for $\bx_i$ is searched. Checking this requires keeping
track of all the inter-center distances, but centers are typically a
small fraction of the training data, so overall this can be a
significant saving. In particular, if this condition is satisfied for
all the centers $\bc \not= \bc_{q_i}$, the point $\bx_i$ can be
skipped completely. Furthermore, the condition can be tested also
based on an upper bound $UB_i$ of $\|\bx_i - \bc_{q_i}\|_p$.
Second, if a center $\bc$ is updated to $\hat{\bc}$, then the new
distance from $\bx$ to $\hat{\bc}$ is bounded from below and above by
\[
\|\bx - \bc\|_p - \|bc - \hat\bc\|_p
\leq
\|\bx - \hat{\bc}\|_p
\leq
\|\bx - \hat{\bc}\|_p + \|\bc + \hat{\bc}\|_p.
\]
This allows to maintain an upper bound on the distance of $\bx_i$ to
its current center $\bc_{q_i}$ and a lower bound to any other center
$\bc$:
@f{align*}
UB_i & \leftarrow UB_i + \|\bc_{q_i} - \hat{\bc}_{q_i} \|_p \\
LB_i(\bc) & \leftarrow LB_i(\bc) - \|\bc -\hat \bc\|_p.
@f}
Thus the K-means algorithm becomes:
1. **Initialization.** Compute $LB_i(\bc) = \|\bx_i -\hat \bc\|_p$ for
all points and centers. Find the current assignments $q_i$ and
bounds $UB_i$ by finding the closest centers to each point: $UB_i =
\min_{\bc} LB_i(\bc)$.
2. **Center estimation.**
1. Recompute all the centers based on the new means; call the updated
version $\hat{\bc}$.
2. Update all the bounds based on the distance $\|\bc - \hat\bc\|_p$
as explained above.
3. Set $\bc \leftarrow \hat\bc$ for all the centers and go to the next
iteration.
3. **Quantization.**
1. Skip any point $\bx_i$ such that $UB_i \leq \frac{1}{2} \|\bc_{q_i} - \bc\|_p$
for all centers $\bc \not= \bc_{q_i}$.
2. For each remaining point $\bx_i$ and center $\bc \not= \bc_{q_i}$:
1. Skip $\bc$ if
\[
UB_i \leq \frac{1}{2} \| \bc_{q_i} - \bc \|
\quad\text{or}\quad
UB_i \leq LB_i(\bc).
\]
The first condition reflects the first observation above; the
second uses the bounds to decide if $\bc$ can be closer than the
current center $\bc_{q_i}$ to the point $\bx_i$. If the center
cannot be skipped, continue as follows.
3. Skip $\bc$ if the condition above is satisfied after making the
upper bound tight:
\[
UB_i = LB_i(\bc_{q_i}) = \| \bx_i - \bc_{q_i} \|_p.
\]
Note that the latter calculation can be done only once for $\bx_i$.
If the center cannot be skipped still, continue as follows.
4. Tighten the lower bound too:
\[
LB_i(\bc) = \| \bx_i - \bc \|_p.
\]
At this point both $UB_i$ and $LB_i(\bc)$ are tight. If $LB_i <
UB_i$, then the point $\bx_i$ should be reassigned to
$\bc$. Update $q_i$ to the index of center $\bc$ and reset $UB_i
= LB_i(\bc)$.

@section kmeans-ann ANN algorithm
<!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->
The *Approximate Nearest Neighbor* (ANN) K-means algorithm
@cite{beis97shape} @cite{silpa-anan08optimised} @cite{muja09fast} is a
variant of Lloyd's algorithm (@ref kmeans-lloyd) uses a best-bin-first
randomized KD-tree algorithm to approximately (and quickly) find the
closest cluster center to each point. The KD-tree implementation is
based on @ref kdtree.
The algorithm can be summarized as follows:
1. **Quantization.** Each point $\bx_i$ is reassigned to the center
$\bc_{q_j}$ closer to it. This starts by indexing the $K$ centers
by a KD-tree and then using the latter to quickly find the closest
center for every training point. The search is approximated to
further improve speed. This opens up the possibility that a data
point may receive an assignment that is *worse* than the current
one. This is avoided by checking that the new assignment estimated
by using ANN is an improvement; otherwise the old assignment is
kept.
2. **Center estimation.** Each center $\bc_q$ is updated to minimize
its average distances to the points assigned to it. It is easy to
show that the best center is the mean or median of the points,
respectively if the $l^2$ or $l^1$ norm is considered.
The key is to trade-off carefully the speedup obtained by using the
ANN algorithm and the loss in accuracy when retrieving neighbors. Due
to the curse of dimensionality, KD-trees become less effective for
higher dimensional data, so that the search cost, which in the best
case is logarithmic with this data structure, may become effectively
linear. This is somehow mitigated by the fact that new a new KD-tree
is computed at each iteration, reducing the likelihood that points may
get stuck with sub-optimal assignments.
Experiments with the quantization of 128-dimensional SIFT features
show that the ANN algorithm may use one quarter of the comparisons of
Elkan's while retaining a similar solution accuracy.

*
* @ingroup plasma_posv
*
* Computes the solution to a system of linear equations A * X = B, where A is
* an n-by-n Hermitian positive definite matrix and X and B are n-by-nrhs matrices.
*
* plasma_zcposv first factorizes the matrix using plasma_cpotrf and uses
* this factorization within an iterative refinement procedure to produce a
* solution with COMPLEX*16 normwise backward error quality (see below). If
* the approach fails the method falls back to a COMPLEX*16 factorization and
* solve.
*
* The iterative refinement is not going to be a winning strategy if
* the ratio COMPLEX performance over COMPLEX*16 performance is too
* small. A reasonable strategy should take the number of right-hand
* sides and the size of the matrix into account. This might be done
* with a call to ILAENV in the future. Up to now, we always try
* iterative refinement.
*
* The iterative refinement process is stopped if iter > itermax or
* for all the RHS we have: Rnorm < sqrt(n)*Xnorm*Anorm*eps*BWDmax
* where:
*
* - iter is the number of the current iteration in the iterative refinement
* process
* - Rnorm is the Infinity-norm of the residual
* - Xnorm is the Infinity-norm of the solution
* - Anorm is the Infinity-operator-norm of the matrix A
* - eps is the machine epsilon returned by DLAMCH('Epsilon').
* The values itermax and BWDmax are fixed to 30 and 1.0D+00 respectively.
*

* If uplo = PlasmaLower, the leading n-by-n lower triangular part of
* A contains the lower triangular part of the matrix A, and the
* strictly upper triangular part of A is not referenced.
* On exit, contains the lower Cholesky factor matrix L,
