scipy.signal.step

scipy.signal.step(system, X0=None, T=None, N=None)[source]

Step response of continuous-time system.

Parameters :

system : an instance of the LTI class or a tuple of array_like

describing the system. The following gives the number of elements in the tuple and the interpretation:

  • 2 (num, den)
  • 3 (zeros, poles, gain)
  • 4 (A, B, C, D)

X0 : array_like, optional

Initial state-vector (default is zero).

T : array_like, optional

Time points (computed if not given).

N : int

Number of time points to compute if T is not given.

Returns :

T : 1D ndarray

Output time points.

yout : 1D ndarray

Step response of system.
