Hello everyone. I have a 4x4 Hamiltonian which is numerical and I want to get its eigenvectors. However I want to get the eigenvectors BEFORE they are normalised to 1 as I need the weights of the wavefunction. Eigenvectors produced both normalized and orthogonal. I tried Eigensystem as well but the wavectors produced were orthogonal as well. Can anyone help me in this?is there a way to get the weights of the wave functions before they are normalised to 1?
