cupyx.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:

    • 1 (instance of lti)

    • 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, optional) – 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.

Notes

If (num, den) is passed in for system, coefficients for both the numerator and denominator should be specified in descending exponent order (e.g. s^2 + 3s + 5 would be represented as [1, 3, 5]).
