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

Simulate output of a discrete-time linear system.

  • system (tuple of array_like or instance of dlti) –

    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)

  • u (array_like) – An input array describing the input at each time t (interpolation is assumed between given times). If there are multiple inputs, then each column of the rank-2 array represents an input.

  • t (array_like, optional) – The time steps at which the input is defined. If t is given, it must be the same length as u, and the final value in t determines the number of steps returned in the output.

  • x0 (array_like, optional) – The initial conditions on the state vector (zero by default).


  • tout (ndarray) – Time values for the output, as a 1-D array.

  • yout (ndarray) – System response, as a 1-D array.

  • xout (ndarray, optional) – Time-evolution of the state-vector. Only generated if the input is a StateSpace system.
