I'm trying to calculate a laplacian spectrum of an adjacency matrix. I tried to look online/youtube but couldn't really find anything. I've added a couple of sample matrices here: Sample adjacency matricies
For matrix A, I calculated the eigenvalues to be:
E = {2.377,-2.247,-1.651,-.555,0,1.274,.802}
but after this step, I'm not too sure what to do. Correct me if I'm wrong, but from my understanding, I multiply A*E to get the spectrum, resulting in:
{.802, -.849,-.973, 2.076, 0.130, -2.206, -0.425}
Any help is appreciated! Thanks!
