ladel_mat_diag_mat_transpose()

ladel_sparse_matrix * ladel_mat_diag_mat_transpose	(	const ladel_sparse_matrix *	M,
		const ladel_sparse_matrix *	M_transpose,
		const ladel_double *	diag,
		ladel_work *	work
	)

Computes \(M\Sigma M^T\).

Parameters

M	Matrix
M_transpose	The transpose of M
diag	Array containing the diagonal of \(\Sigma\)
work	LADEL workspace

ladel_sparse_matrix * ladel_mat_mat_transpose	(	const ladel_sparse_matrix *	M,
		const ladel_sparse_matrix *	M_transpose,
		ladel_work *	work
	)

Computes \(MM^T\).

Parameters

M	Matrix
M_transpose	The transpose of M
work	LADEL workspace

Returns

\(MM^T\)

ladel_sparse_matrix * ladel_mat_mat_transpose_advanced	(	const ladel_sparse_matrix *	M,
		const ladel_sparse_matrix *	M_transpose,
		const ladel_double *	diag,
		ladel_int	values,
		ladel_work *	work
	)

Core mat_mat_transpose function with all options (diag and value/pattern).

Note

If values==FALSE, only the pattern of \(MM^T\). Setting diag=NULL, then \(\Sigma = I\) is assumed.

Parameters

M	Matrix
M_transpose	Transpose of M
diag	Array containing the diagonal of \(\Sigma\). If NULL, \(\Sigma = I\).
values	Values or pattern computation
work	LADEL workspace

	)

Computes the pattern of \(MM^T\).

Parameters

M	Matrix
