Or outer product, ones(4,1)*[1:4].  Probably several ways.

This list is more geared for questions about bugs, new features, better 
programming, etc. as opposed to questions about how to use the language.

Octave has a very nice help feature.  "help" followed by the name of the

is the "doc" help feature which gives an overview of arithmetic 
expressions, syntax, so on.
