Help with meshz comparison

[Rik]

The color that Octave uses for the waterfall portion of a meshz plot is the
minimum value of Z, but Matlab appears to use the mean or median.  Can
someone run the following code in Matlab and send the picture and the data?

Test Code:

Z = peaks ();
h = meshz (Z(20:30, 20:30));
print -dpng tst.png
cdat = get (h, 'cdata');
cdat(1:5, 1:5)

Thanks,
Rik
