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

Simulate output of a discrete-time linear system.

Parameters:

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).

Returns:

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.
