22*bf2c3715SXin Li  * This module provides an interface to the Cholmod library which is part of the <a href="http://www.suitesparse.com">suitesparse</a> package.
23*bf2c3715SXin Li  * It provides the two following main factorization classes:
24*bf2c3715SXin Li  * - class CholmodSupernodalLLT: a supernodal LLT Cholesky factorization.
25*bf2c3715SXin Li  * - class CholmodDecomposiiton: a general L(D)LT Cholesky factorization with automatic or explicit runtime selection of the underlying factorization method (supernodal or simplicial).
26*bf2c3715SXin Li  *
27*bf2c3715SXin Li  * For the sake of completeness, this module also propose the two following classes:
28*bf2c3715SXin Li  * - class CholmodSimplicialLLT
29*bf2c3715SXin Li  * - class CholmodSimplicialLDLT
30*bf2c3715SXin Li  * Note that these classes does not bring any particular advantage compared to the built-in
31*bf2c3715SXin Li  * SimplicialLLT and SimplicialLDLT factorization classes.

37*bf2c3715SXin Li  * In order to use this module, the cholmod headers must be accessible from the include paths, and your binary must be linked to the cholmod library and its dependencies.
38*bf2c3715SXin Li  * The dependencies depend on how cholmod has been compiled.
39*bf2c3715SXin Li  * For a cmake based project, you can use our FindCholmod.cmake module to help you in this task.
