/** \ingroup Support_modules | |

* \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. | |

* | |
