int get_dot_product_of_matrix_rows_2
(
	const Matrix *first_mp,
	int r1,
	const Matrix *second_mp,
	int r2,
	double *dot_prod_ptr
);

DESCRIPTION

This routine computes the dot product of two matrix rows. It is similar to get_dot_product_of_matrix_rows(), except that the matrix rows come from (presumably) different matrices.

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.
