what codes are needed to make the surface produced by surf have a unified color?

Hi everyone,

I am using "surf" to produce a 3D surface. However, the color of it is changing with the value of Z in the surface.

How can I make the color of the surface to be unified to only one kind?

THX very much!

Cheers

Do you mean that you only want the same colour for every point on the 3D surface? If so, after you have called surf3 just change the colormap to a single colour (see http://www.mathworks.com/help/matlab/ref/surf.html for a two colour example):

 colormap([1 0 0]);

would change the surface to red.
