Detailed Description
template<typename MatrixType>
class Eigen::PardisoLU< MatrixType >
A sparse direct LU factorization and solver based on the PARDISO library.
This class allows to solve for A.X = B sparse linear problems via a direct LU factorization using the Intel MKL PARDISO library. The sparse matrix A must be squared and invertible. The vectors or matrices X and B can be either dense or sparse.
By default, it runs in in-core mode. To enable PARDISO's out-of-core feature, set:
solver.pardisoParameterArray()[59] = 1;
- Template Parameters
-
_MatrixType the type of the sparse matrix A, it must be a SparseMatrix<>
