* \brief Provides QR decomposition for sparse matrices |
|
|
* |
|
|
* This module provides a simplicial version of the left-looking Sparse QR decomposition. |
|
|
* The columns of the input matrix should be reordered to limit the fill-in during the |
|
|
* decomposition. Built-in methods (COLAMD, AMD) or external methods (METIS) can be used to this end. |
|
|
* See the \link OrderingMethods_Module OrderingMethods\endlink module for the list |
|
|
* of built-in and external ordering methods. |
