Follow-up Comment #1:

Thanks. This should be an easy fix in the meshgrid.m file.

This does work if nargout == 3, but Octave is using nargout to determine
whether the space should be 2 or 3 dimensions and ignoring the 3rd input
argument if nargout < 3.


>> x = meshgrid(1:2, 1:3, 1:5); size (x)
ans =

   3   2

>> [x,~,~] = meshgrid(1:2, 1:3, 1:5); size (x)
ans =

   3   2   5



If nargin == 1, then the results should still be based on nargout as it is
done currently, but if nargin > 1 then the output should probably be derived
from that.
