  * \defgroup SparseCholesky_Module SparseCholesky module
  *
  * This module currently provides two variants of the direct sparse Cholesky decomposition for selfadjoint (hermitian) matrices.
  * Those decompositions are accessible via the following classes:
  *  - SimplicialLLt,
  *  - SimplicialLDLt
  *
  * Such problems can also be solved using the ConjugateGradient solver from the IterativeLinearSolvers module.
