Eigen  3.3.4
SparseCholesky module

Detailed Description

This module currently provides two variants of the direct sparse Cholesky decomposition for selfadjoint (hermitian) matrices. Those decompositions are accessible via the following classes:

Such problems can also be solved using the ConjugateGradient solver from the IterativeLinearSolvers module.
