[Gretl-users] reversing / flipping a matrix

Dear gretl users, yesterday I needed to flip a matrix/vector around by reversing the order of the elements. (I guess like rev() or flipud() in other languages.) But I didn't find the function to do that, so I used an inefficient workaround using msortby(). But since this seems like quite basic functionality I think I either missed something or it should be added, right? thanks, sven
