(
	Matrix *source_mp,
	const Vector *vp
);

DESCRIPTION

This routine multiplies each column of the input matrix by a vector. The length of the vector must match the number of rows in the matrix.

RETURNS

NO_ERROR on success, and ERROR on failure, with an error message being set. Currenly this routine can't fail gracefully. The routine will fail due to dimension mismatch, but this is currently treated as a bug (see set_bug()).
