Hi Miles,

I have two quick questions.

Is there a way to convert an arbitrary vector to MPS or IQMPS as an initial state?

I wanted to exponentiate the Hamiltonian exactly for time evolution of small systems. But toExpH(ampo, tau) is only approximately equal to exp(-tau*H) up to terms of order tau^2. How can I do it exactly?

Thanks for all your help.
