Function Documentation

scamac_sparsemat_check()

bool scamac_sparsemat_check

(

const ScamacMatrix *

sm

)

basic sanity check for sparse matrix

Returns

Error code

Note

Does not complain about zero matrix entries.

scamac_sparsemat_to_dense()

ScamacErrorCode scamac_sparsemat_to_dense	(	const ScamacMatrix *	sm,
		void **	dm
	)

convert sparse matrix to dense matrix

Note

If dm = NULL, the dense matrix is allocated in the function (and should be free'd eventually). Otherwise, we expect that dm points to an nrow*ncol(1 for real, 2 for complex) array of doubles.
