I am trying to display a rgb colour map on a gridded surface using surf.
I have grids of each rgb colour. How do I combine to give the surf(x,y,z,C)?
thanks

Sorry Ameer, you're absolutely right. Sometimes I work on too many problems too close together. I must have gotten confused.

You can use texture mapping to display an RGB image on a surface(). See here: https://www.mathworks.com/matlabcentral/answers/91858-is-it-possible-to-perform-texture-mapping-within-matlab. For example
img = imread('pears.png');
z = peaks(100);
surf(z, ...
'FaceColor','texturemap',...
'EdgeColor','none',...
'Cdata',img)
view(3)
