Is there a better way to combine the first two axes of an array when the second axis's shape is 1 than using transpose. I can achieve the desired result using transpose, as in ,"2&.|: . (I have always assumed transpose was inefficient, but maybe not.)
$ ,"2&.|: i. 3 1 5 5 3 5 5 -- (B=) ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
