Hello, I'm working in Graph Spectra. The problem is that I want to find the eigenvalues and eigenvectors of a matrix with complex numbers. For instance, my matrix is: [0 1+i 2i 3;1+i 0 3 1+4i;2i 3 0 1i;3 1+4i 1i 0] I would like to know if the matlab function eig works for this kind of calculations. The idea is to find the partitioning with the second eigenvector. If there is anybody working on this subject, I would like to have a little help. Thank you!

The regular EIG function seems to work:
A =[0 1+i 2i 3;1+i 0 3 1+4i;2i 3 0 1i;3 1+4i 1i 0];
[E,V] = eig(A)

Yes, it does.
A = [0 1+i 2i 3;1+i 0 3 1+4i;2i 3 0 1i;3 1+4i 1i 0];
[V,D] = eig(A);
V*D
%compare to
A*V

[T, J] = jordan(A)
