An earlier question here mentioned Control`PoleZeroPlot
, which I've found useful. Typing Names["*`PoleZeroPlot]
returns
{"Charting`PoleZeroPlot", "Control`PoleZeroPlot", "PoleZeroPlot"}
(I'm substituting single quote ' for back-tick above because I can't figure out how to escape the back-tick character.)
Mysteriously, when I type PoleZeroPlot
into Mathematica, it knows nothing about it. Digging around in the installation directories for Mathematica doesn't turn up any Control
package. Where can I find documentation on PoleZeroPlot
?
