scipy.signal.dstep¶

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

Step response of discrete-time system.

Parameters

systemtuple 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)

x0array_like, optional

Initial state-vector. Defaults to zero.

tarray_like, optional

Time points. Computed if not given.

nint, optional

The number of time points to compute (if t is not given).

Returns

toutndarray: Output time points, as a 1-D array.
youttuple 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.
