Detailed Description

template<typename _MatrixType, int _UpLo>
class Eigen::PastixLLT< _MatrixType, _UpLo >

A sparse direct supernodal Cholesky (LLT) factorization and solver based on the PaStiX library.

This class is used to solve the linear systems A.X = B via a LL^T supernodal Cholesky factorization available in the PaStiX library. The matrix A should be symmetric and positive definite WARNING Selfadjoint complex matrices are not supported in the current version of PaStiX The vectors or matrices X and B can be either dense or sparse

Template Parameters:
MatrixTypethe type of the sparse matrix A, it must be a SparseMatrix<>
UpLoThe part of the matrix to use : Lower or Upper. The default is Lower as required by PaStiX
