PoleZeroMarkers

is an option for RootLocusPlot that specifies the markers to be drawn on the complex plane at the open-loop poles, closed-loop poles, and open-loop zeros.

Details

  • PoleZeroMarkers->{gop,gcp,gz} specifies that gop, gcp, and gz must be the markers for the open-loop poles, closed-loop poles, and open-loop zeros.
  • PoleZeroMarkers has the same settings as PlotMarkers.
  • PoleZeroMarkers->{…,"ParameterValues"->{k1,k2,…,kn}} shows the closed-loop values at the parameter values ki.
  • With "ParameterValues"->n, the poles at n equally spaced parameter values are shown.

Examples

Basic Examples  (5)

By default, the open-loop poles, closed-loop poles, and open-loop zeros use "×", "", and "∘":

Specify the markers:

By default the closed-loop poles at the midpoint of the parameter range are shown:

Specify parameter values at which to show the closed-loop poles:

Show closed-loop poles at equally spaced parameter values:
