How can I set the color of a surfplot?

Hello,

i have created a 3d-mesh with following code

if true
RTHETA=-pi/2:0.03:pi/2;%Polar
RPHI=0:0.03:2*pi;   %Azimut
[THETA PHI]=meshgrid(RTHETA,RPHI);
ZP=abs(sinc(15*sin(THETA).*cos(PHI)/pi).*sinc(5*sin(THETA).*sin(PHI)/pi));
end

Now I want to plot this function in sphere coordinates. So I did a transform:

if true
I=ZP.*sin(THETA).*cos(PHI);
J=ZP.*sin(THETA).*sin(PHI);
K=ZP.*cos(THETA);
end

Now I want to plot this

if true
  surf(I,J,K)
end

It works, but the color map is not so perfect. Because you cant almost see no details. Now I want to set the color of a point corresponding to its curvature. I found the function:

if true
  Q=surfature(I,J,K);
end

And there was no error, but now I dont know how to combine it with my plot. Can you help me with this? Thank you!

Kind Regards Martin

surf(I, J, K, Q)
