 | Subject: meshdom and mesh bugs
 | Bug report for Octave 1.1.1 configured for i486-unknown-linux
 | Description:
 | - -----------
 | 1. meshdom produces a Y matrix with entries in an unexpected order.

Well, I think that jwe does a good job trying to keep compatibility with
Matlab, but I think that what is wrong should not be keep compatible...
If you observe the XYZ vectorial product rule, then mesh is wrong...

I notice the bug when doing plots of non-simetrical functions (unlike
the sombrero one), and I spent some time looking what was wrong with
_my_ functions, just to discover some hours late that it was not
_my_ problem, but _mesh_ problem. Perhaps MATLAB should correct the bug?
