Step response of continuous-time system.
Inputs:
- system – an instance of the LTI class or a tuple with 2, 3, or 4
- elements representing (num, den), (zero, pole, gain), or (A, B, C, D) representation of the system.
X0 – (optional, default = 0) inital state-vector. T – (optional) time points (autocomputed if not given). N – (optional) number of time points to autocompute (100 if not given).
Ouptuts: (T, yout)
T – output time points, yout – step response of system.
