How to plot the 2d complex function with amplitude and phase

4 views (last 30 days)
I have a 2d complex function as follows
psi=sqrt(x^2+y^2)*exp(-(x^2+y^2)/16)*exp(i*atan2(y,x));
How to realize the following figure by using Matlab?
In this image, the color on the ring presents the changes of phase of the function from small to big.
