Help with surfnorm compatibility

[Rik]

I'm trying to see whether Matlab uses colororder or the existing colormap
to determine the color for the normal vectors in surfnorm.  Could someone
run the following code in Matlab and return the two images.

clf;
colormap ('hsv');
[x,y,z] = cylinder (1:10);
surfnorm (x,y,z);
print -dpng hsv.png
colormap ('jet');
print -dpng jet.png

Thanks,
Rik
