Hello! Multiply and add doesn't seem to work with axis specifications:
(3 5⍴1) ×[1] ⍳3 INDEX ERROR (3 5⍴1)×[1]⍳3 ^ ^ INDEX ERROR (3 5⍴1)+[1]⍳3 ^ ^ This works in NARS2000 and Dyalog: (3 5⍴1) ×[1] ⍳3 1 1 1 1 1 2 2 2 2 2 3 3 3 3 3 (3 5⍴1)+[1]⍳3 2 2 2 2 2 3 3 3 3 3 4 4 4 4 4 Now, I don't have a copy of the standard to check (the pdf file from the link mentioned in README-7-more-info seems to be corrupted – I couldn't open it), but according to the draft (disS8485.pdf), these functions don't take axis specifications. On the other hand, this works: (3 5⍴1) +[2] ⍳5 2 3 4 5 6 2 3 4 5 6 2 3 4 5 6 Regards, Daniel
