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? Thanks, Joao -- Joao Cardoso, INESC | e-mail: jcard at zorg dot tecno dot inescn dot pt R.
