(
	Int_matrix *first_mp,
	const Int_matrix *second_mp
);

DESCRIPTION

This routine performs element-wise subtraction of two matrices. The second matrix must fit into the first an integral number of times. For example, if the first matrix has dimenions 6x3, then the second can have dimensions 6x3 (the common case), 6x1, 3x3, 2x3, 1x6, etc, but NOT 2x2, 5x1, etc. The second matrix is subtracted from each block in the first matrix. The first matrix is thus over-written.

RETURNS

NO_ERROR on success, and ERROR on failure, with an error message being set.

DISCLAIMER

This software is not adequatedly tested. It is recomended that results are checked independantly where appropriate.
