control.matlab.pzmap

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.

Notes

This function is a wrapper for pole_zero_plot(), with legacy return arguments.
