how to draw a temperature distribution on (x,y,z)?

I have 3 coordinates x,y,z. For each x,y,z I have a corresponding temperature t. How can I draw it in matlab to get a "smooth" graph as in the below matlab example?

I have the same problem. If you have found a solution let me know.

http://www.mathworks.com/help/matlab/visualize/representing-a-matrix-as-a-surface.html should help.

The image you have attached was generated using:

 [X,Y] = meshgrid(-8:.5:8);
 R = sqrt(X.^2 + Y.^2) + eps;
 Z = sin(R)./R;
 figure
 surf(X,Y,Z,'FaceColor','interp',...
   'EdgeColor','none',...
   'FaceLighting','phong')
 daspect([5 5 1])
 axis tight
 view(-50,30)
 camlight left

You can replace 'Z' here with the temperature data you have.

thanks Amith

but Z is a third coordinate, not temperature. where do I put variable T?
