Logarithmic axes on 3d plots

Hi!

My question is: is it possible to draw 3D plots, such as
surface plots or contour plots with one, or several,
logarithmic axes?

I know of no option to do this, as in 2D specific functions
are used (semilogx, ...).

Thanks in advance for your help!

Hi,
after plotting your function set the property of the z axes:
set(gca, 'zscale', 'log')
