Is there a general verb that can reshape any noun with 1s in its shape so that the axes with 1s disappear? I know that most often changing calculations slightly can eliminate the 1s before they arise, but not always.
For example if $a == 4 1 4 3, is there a verb that will make generalize the result like how ,"_2]1|: does in this case? $,"_2]1|:a == 4 4 3 -- (B=) ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
