typedef SparseSolverBase< SuperLU< _MatrixType > > | Base |
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.
_MatrixType | the type of the sparse matrix A, it must be a SparseMatrix<> |

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.
