Eigen::SuperLU

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.

This class follows the sparse solver concept .

analyzePattern()

template<typename _MatrixType >
void Eigen::SuperLU< _MatrixType >::analyzePattern ( const MatrixType & matrix )
inline

Performs a symbolic decomposition on the sparcity of matrix.

This function is particularly useful when solving for several problems having the same structure.

factorize()

template<typename MatrixType >
void Eigen::SuperLU< MatrixType >::factorize ( const MatrixType & matrix )

Performs a numeric decomposition of matrix

The given matrix must has the same sparcity than the matrix on which the symbolic decomposition has been performed.
