I would like to plot a variable (e.g.: temperature) on a surface in 3D.
In my case the surface is a cylinder which can be plotted in 3D, but I

have only been able to color the surface based on the value of z.
How to do this?

Both mesh and surf accept a fourth argument which is mapped to the colormap.

mesh (x, y, z, c)

Unfortunately the documentation doesn't mention it. I'll add it to the bug tracker.
