Dear Itensor,

I'm computing the time evolution of MPS according to this webpage https://itensor.org/docs.cgi?page=formulas/tevol_mps_mpo. Say that before the time evolution, I have MPS psi*0, and after the time evolution I end up with MPS psi*1. How should I compute the inner product between psi*0 and psi*1? (I tried psi*0 * psi*1 directly, but it didn't seem to work.)

Thanks very much!
