Detailed Description
template<typename _MatrixType, int _UpLo>
class Eigen::PastixLLT< _MatrixType, _UpLo >
Class to invoke the Pastix LLT solver.
After the class is instantianted, use iparm(IPARM_VERBOSE)=PastixVerboseNo or PastixVerboseYes to get more verbose output from pastix
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
-
MatrixType the type of the sparse matrix A, it must be a SparseMatrix<> UpLo The part of the matrix to use : Lower or Upper. The default is Lower as required by PaStiX
