Hello, Can I ask question about step_info in https://github.com/python-control/python-control/blob/main/control/timeresp.py According to this link sys = TransferFunction([-1, 1], [1, 1, 1]) S = step_info(sys) for k in S: print(f"{k}: {S[k]:3.4}") How is the transfer function S[k] in the for loop determined? For example, what would S[k] be if my system was sys = TransferFunction(2, [1, 1, 2]) or how can I get information of stepinfo from the system
