Hi there,

If I have a square matrix H=randi(N,N)+1i*randi(N,N); how can I plot the maginitude of this matrix H in 3D?

DID YOU TRY IT? Why not?

So, given some arbitrary complex matrix, how do you compute the magnitude? ABS does that. How you you plot the matrix? Use surf. Or you could use pcolor. Or you could use mesh. Or use surfc. I'm sure there are some other options I could think of too.

N = 10;

H = rand(N,N) + i*rand(10,10);

MagH = abs(H);

surf(MagH)
