I've used surf order with a simple method surf(X,Y,Z). X and Y are p*1 matrices and Z is a p*p matrix. I want to use colors to show me differences for z value, but as you see in my surf colors are not used to show contours for z value and maybe this contour is meaningless. How can I solve the problem?
