| const Vector< int > & Seldon::MatrixSuperLU_Base< T >::GetColPermutation | ( | ) | const |
Returns the permutation of columns.
In order to retain the sparsity as much as possible, SuperLU permutes rows and columns before the factorization. This method returns the column permutation that was employed in the factorization. This method is obviously to be called after the factorization has been performed.
- Returns:
- The permutation of the columns.

| void Seldon::MatrixSuperLU_Base< T >::GetLU | ( | Matrix< double, Prop, RowSparse, Allocator > & | Lmat, | |
| Matrix< double, Prop, RowSparse, Allocator > & | Umat, | |||
| bool | permuted = true | |||
| ) |
Returns the LU factorization.
- Parameters:
-
[out] Lmat matrix L in the LU factorization. [out] Umat matrix U in the LU factorization. [in] permuted should the permuted matrices be provided? SuperLU permutes the rows and columns of the factorized matrix. If permuted is set to true, L and U are returned as SuperLU computed them, hence with permuted rows and columns. If permuted is set to false, the matrices L and U are "unpermuted" so that L times U is equal to the initial matrix.
- Note:
- This method will first retrieve the L and U matrices in 'ColSparse' format and then convert them into 'RowSparse'.
