- scipy.signal.dstep(system, x0=None, t=None, n=None)¶
Step response of discrete-time system.
system : tuple of array_like
A tuple describing the system. The following gives the number of elements in the tuple and the interpretation:
- 3: (num, den, dt)
- 4: (zeros, poles, gain, dt)
- 5: (A, B, C, D, dt)
x0 : array_like, optional
Initial state-vector. Defaults to zero.
t : array_like, optional
Time points. Computed if not given.
n : int, optional
The number of time points to compute (if t is not given).
tout : ndarray
Output time points, as a 1-D array.
yout : ndarray
Step response of system. Each element of the tuple represents the output of the system based on a step response to each input.
