Hi ! In J the outer product has the form: a foo/ b. It doesn't work for comma. Example a=: i. 3 b=: i.4 [ a ,/ b 0 1 2 0 1 2 3 APL a °. , b 0 0 0 1 0 2 0 3 1 0 1 1 1 2 1 3 2 0 2 1 2 2 2 3
3 x 4 boxed result Can I have the same result in J as easily as in APL? Best regards ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
