i have a complex matrix (480*640double) ,i cant plot it to 3D coz i had ??? Error using ==> mesh at 80 X, Y, Z, and C cannot be complex.
plzzzzz how to solve it?????

Create a domain
[X,Y] = meshgrid(linspace(-pi,pi));
Evaluate f(z) = log(z) for complex z. F is a complex matrix that represents the complex natural log over the imaginary plane
F = log(X+sqrt(-1)*Y);
Visualize all three components of F:
figure,surf(X,Y,abs(Z)),title('magnitude of F'),xlabel('real'),ylabel('complex')
figure,surf(X,Y,real(Z)),title('Real values of F'),xlabel('real'),ylabel('complex')
figure,surf(X,Y,imag(Z)),title('Complex values of F'),xlabel('real'),ylabel('complex')

Skip the F(z)=log(z); line: it was theoretical rather than actual code.

Replace F = log(X+sqrt(-1)*Y) with Z = log(X+sqrt(-1)*Y);
