int is_matrix_element_equal_to
(
	const Matrix *mp,
	int row,
	int col,
	void *params
);

DESCRIPTION

This routine is a predicate for the find_in_matrix_as_vector routine. It returns 1 if mp->elements[row][col] is equal to *params (cast to a double).

RETURNS

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

DISCLAIMER

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