In the recent Hofstadter-Conway thread, I used complex&# to expand a vector. However, the solution was slightly complicated (and slowed) by the fact that # only allows me to specify fills *after* an element.
It would be nice if # were extended such that if the imaginary component of a complex argument were negative, then the fills would *precede* the corresponding element in the output. That is, (m j. n)&# works as it does today if n is positive or zero, but if n is negative then the fills come before, not after. I've needed this before; see, e.g. the bottom of: http://www.jsoftware.com/pipermail/programming/2007-January/004750.html -Dan ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
