Surfplot with surface color as a function of gradient (slope)

Hi,

I would like to plot a surface plot, where i would like to vary the surface color based on the gradient of z instead of its magnitude. Is there a way to do it?

Thanks and Regards

Answer 1

[Karthik Vemireddy]

found the answer.

surf(X,Y,Z,C) additionally specifies the surface color.

[dfdx,dfdy] = gradient(Z);
surf(x,y,Z,sqrt(dfdx.^2 + dfdy.^2))
colorbar

does the trick...

if true
  surf(X,Y,Z) 
end

surf(X,Y,Z) creates a three-dimensional surface plot. The function plots the values in matrix Z as heights above a grid in the x-y plane defined by X and Y. The function also uses Z for the color data, so color is proportional to height.
