Is there a better way (rhetorical question) to promote an n-element vector, i.e. of of shape N to a single row matrix of shape (1 N) ? The best I have come up with so far is: v2m =. ] $~ 1,$
I have read up on m"n in the Dictionary, but can't make much sense of it. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
