template<typename _MatrixType>
class Eigen::SuperILU< _MatrixType >
A sparse direct incomplete LU factorization and solver based on the SuperLU library.
This class allows to solve for an approximate solution of A.X = B sparse linear problems via an incomplete LU factorization using the SuperLU library. This class is aimed to be used as a preconditioner of the iterative linear solvers.
- Warning
- This class is only for the 4.x versions of SuperLU. The 3.x and 5.x versions are not supported.
- Template Parameters
-
_MatrixType the type of the sparse matrix A, it must be a SparseMatrix<>
This class follows the sparse solver concept .
