/** \ingroup Support_modules
 * \defgroup PaStiXSupport_Module PaStiXSupport module
 *
 * This module provides an interface to the <a href="http://pastix.gforge.inria.fr/">PaSTiX</a> library.
 * PaSTiX is a general \b supernodal, \b parallel and \b opensource sparse solver.
 * It provides the two following main factorization classes:
 * - class PastixLLT : a supernodal, parallel LLt Cholesky factorization.
 * - class PastixLDLT: a supernodal, parallel LDLt Cholesky factorization.
 * - class PastixLU : a supernodal, parallel LU factorization (optimized for a symmetric pattern).
 *
 * \code
 * #include <Eigen/PaStiXSupport>
 * \endcode
 *
 * In order to use this module, the PaSTiX headers must be accessible from the include paths, and your binary must be
 * linked to the PaSTiX library and its dependencies. This wrapper resuires PaStiX version 5.x compiled without MPI
 * support. The dependencies depend on how PaSTiX has been compiled. For a cmake based project, you can use our
 * FindPaSTiX.cmake module to help you in this task.
