Continuing my J 101 questions, what's the best way to do a cyclical (as opposed to element-wise) copy?
(2#1 2) gives (1 1 2 2), I want (1 2 1 2). The best I've come up with is (,2#,:1 2). Is there a better way, or is that it? Cheers, Johann ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
