int find_in_matrix_by_rows
(
	Int_vector **indices,
	const Matrix *mp,
	int (*predicate)(const Matrix *,int,void *),
	void *params
);

DESCRIPTION

This routine searches the matrix mp for rows which return 1 on the given predicate. That is, row index i is inserted in *indices if and only if predicate(mp, i, ...) returns 1. *indices is an integer vector that holds all row indices which fulfill the mentioned condition. *indices can then be used as input to any of the copy functions. If *indices is NULL, it is created; if it is the wrong size, it is resized; finally, if it is the right size, the storage is recycled, as is.

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.
