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.

DetailsDetails

  • PoleZeroMarkers->{gop, gcp, gz} specifies that , , and 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 .
  • With "ParameterValues"->n, the poles at n equally spaced parameter values are shown.
