Signature

def output(self, u, t, x0 = None)

Return the response of the discrete-time system to input u.

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 2D 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.
