- control.matlab.pzmap(sys[, grid, plot])[source]
Plot a pole/zero map for a linear system.
- Parameters
sys (LTI (StateSpace or TransferFunction)) – Linear system for which poles and zeros are computed.
plot (bool, optional) – If
True
a graph is generated with Matplotlib, otherwise the poles and zeros are only computed and returned.grid (boolean (default = False)) – If True plot omega-damping grid.
- Returns
poles (array) – The system’s poles.
zeros (array) – The system’s zeros.
