So will it work for me? From what I've told you so far?

It does some CSD. But the algorithm is specific to quantum computing,
so I doubt it is in scipy.linalg. Although I'm not sure how much of
this code is CSD and how much is other stuff. It's possible I guess to
use scipy.linalg and rewrite the supporting stuff in python directly.
