Well, ask a poorly specified question get a smart answer.  You cracked 
me up too.

I don't know the dimensions or the direction a-priori.  The obvious 
answer is 1:N followed by a repmat but there are so many cute little 
octave tricks that I was hoping there was something really clever.  I am 
still trying to understand broadcasting in full, but I don't think it 
quite works for my application.  Bob will noodle a bit.  Thanks for the 
response, even it if was a bit of a kick in the private parts.
