Detailed Description

template<typename _MatrixType>
class Eigen::SuperLU< _MatrixType >

A sparse direct LU factorization and solver based on the SuperLU library.

This class allows to solve for A.X = B sparse linear problems via a direct LU factorization using the SuperLU library. The sparse matrix A must be squared and invertible. 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<>

Warning: This class is only for the 4.x versions of SuperLU. The 3.x and 5.x versions are not supported.
