get_perm_c_batch()

void get_perm_c_batch	(	superlu_dist_options_t *	options,
		int	batchCount,
		handle_t *	SparseMatrix_handles,
		int **	CpivPtr
	)

Gets sparsity permutations for a batch of matrices.

Parameters

  

    
[in]
options
solver options

    
[in]
batchCount
number of matrices in the batch

    
[in]
SparseMatrix_handles
pointers to the matrices in the batch, each pointing to the actual stoage in CSC format
    On entry, the original matrices, may be overwritten by A1 <- Pr*diag(R)*A*diag(C) from dequil_batch() and dpivot_batch()

    
[out]
CpivPtr
pointers to column permutation vectors for each matrix, each of size n
