cupyx.scipy.signal.dstep(system, x0=None, t=None, n=None)[source]#

Step response of discrete-time system.

Parameters:

system (tuple of array_like) –
A tuple describing the system. The following gives the number of elements in the tuple and the interpretation:
- 1: (instance of dlti)
- 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).

Returns:

tout (ndarray) – Output time points, as a 1-D array.
yout (tuple of ndarray) – Step response of system. Each element of the tuple represents the output of the system based on a step response to each input.
