I am currently working on a project where I need to decompose my system into observable and unobservable subsystems in an efficient way, so I was looking for a function that could help me with that.
PS: I know about this function and it is not was I am looking for:
s = co.ss(A, B, C, D)
sys, T = co.observable_form(s)
In this case, the system needs to be fully observable.
Thank you!
