21+
*
22+
* This module provides an interface to the Cholmod library which is part of the <a href="http://www.suitesparse.com">suitesparse</a> package.
23+
* It provides the two following main factorization classes:
24+
* - class CholmodSupernodalLLT: a supernodal LLT Cholesky factorization.
25+
* - class CholmodDecomposiiton: a general L(D)LT Cholesky factorization with automatic or explicit runtime selection of the underlying factorization method (supernodal or simplicial).
26+
*
27+
* For the sake of completeness, this module also propose the two following classes:
28+
* - class CholmodSimplicialLLT
29+
* - class CholmodSimplicialLDLT
30+
* Note that these classes does not bring any particular advantage compared to the built-in
31+
* SimplicialLLT and SimplicialLDLT factorization classes.
32+
*
33+
* \code
34+
* #include <Eigen/CholmodSupport>
35+
* \endcode
36+
*
37+
* 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+
* The dependencies depend on how cholmod has been compiled.
39+
* For a cmake based project, you can use our FindCholmod.cmake module to help you in this task.
