int copy_matrix_with_selection_2
(
	Matrix **target_mpp,
	const Matrix *source_mp,
	const Int_vector *rows,
	const Int_vector *cols
);

DESCRIPTION

This routine copies the elements (specified in the binary vectors rows and cols) of matrix source_mp into vector *matrix_mpp. A row (column) is copied if and only if the corresponding element of rows (cols) is non-zero. This means that rows->length must be equal to source_mp->num_rows. The analogous statement must hold for cols->length. If rows (cols) is NULL, then all the rows (columns) are copied. As a special case of this, if both rows and cols are NULL, then copy_matrix is invoked. If *target_vpp 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.
