No, never mind. I see this usage of repmat works in 2.9.9 (and I also
see I was confused about the source of some of the functions; I
thought that meshgrid was a 'forge function, but I see now it isn't).
The only problem in 2.9.9 is that the help documentation doesn't
reflect the fact that repmat works on N-d arrays...
