impulse(sys, T=None, X0=0.0, input=0, output=None, return_x=False)¶
Impulse response of a linear system
If the system has multiple inputs or outputs (MIMO), one input has to be selected for the simulation. Optionally, one output may be selected. If no selection is made for the output, all outputs are given. The parameters input and output do this. All other inputs are set to 0, all other outputs are ignored.
- sys (StateSpace, TransferFunction) – LTI system to simulate
- T (array-like object, optional) – Time vector (argument is autocomputed if not given)
- X0 (array-like or number, optional) –
Initial condition (default = 0)
Numbers are converted to constant arrays with the correct shape.
- input (int) – Index of the input that will be used in this simulation.
- output (int) – Index of the output that will be used in this simulation.
- yout (array) – Response of the system
- T (array) – Time values of the output
- xout (array (if selected)) – Individual response of each x variable
