| * \defgroup SuperLUSupport_Module SuperLUSupport module | |
| * | |
| * This module provides an interface to the <a href="http://crd-legacy.lbl.gov/~xiaoye/SuperLU/">SuperLU</a> library. | |
| * It provides the following factorization class: | |
| * - class SuperLU: a supernodal sequential LU factorization. | |
| * - class SuperILU: a supernodal sequential incomplete LU factorization (to be used as a preconditioner for iterative methods). | |
| * | |
| * \warning This wrapper requires at least versions 4.0 of SuperLU. The 3.x versions are not supported. | |
| * | |
| * \warning When including this module, you have to use SUPERLU_EMPTY instead of EMPTY which is no longer defined because it is too polluting. | |
| * | |
| * \code | |
| * #include <Eigen/SuperLUSupport> | |
| * \endcode | |
| * | |
| * In order to use this module, the superlu headers must be accessible from the include paths, and your binary must be linked to the superlu library and its dependencies. | |
| * The dependencies depend on how superlu has been compiled. | |
| * For a cmake based project, you can use our FindSuperLU.cmake module to help you in this task. | |
