PoleZeroMarkers

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.
  • PoleZeroMarkers specifies that , , and must be the markers for the open-loop poles, closed-loop poles, and open-loop zeros.
  • With "ParameterValues"->n, the poles at n equally spaced parameter values are shown.
By default the open-loop poles, closed-loop poles, and open-loop zeros are marked using "", "×", and "", respectively:
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:
By default the open-loop poles, closed-loop poles, and open-loop zeros are marked using "", "×", and "", respectively:
