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

44 views (last 30 days)
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

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.
