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
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 |
This class follows the sparse solver concept .
