setting color using surf in axes (guide)

Dear all,

I'm doing a surface plot in an axes object (guide), but the surface don't get any color. What should I do to get color in the surface?.

I'm using following commands:

axes(handles.axes1)

[X,Y,Z] = peaks(25);

C = X.*Y;

surf(X,Y,Z,C)

Regards,

Luis

The following code works, but when I use alpha(.5) or surf(X,Y,Z,CO,'FaceColor', 'interp','FaceAlpha',0.5), the surface get without color. What should I do to get transparency?:

axes(handles.axes1)
[X,Y,Z] = peaks(25);
CO(:,:,1) = zeros(25); 
CO(:,:,2) = ones(25)*0.2; 
CO(:,:,3) = abs(Z)./max(max(Z)); 
surf(X,Y,Z,CO,'FaceColor', 'interp')

Thanks

[X,Y,Z] = peaks(25);
CO(:,:,1) = zeros(25); 
CO(:,:,2) = ones(25)*0.2; 
CO(:,:,3) = abs(Z)./max(max(Z)); 
surf(X,Y,Z,CO)
alpha 0.5 ;
