MATLAB: Change pzplot marker size

pzplot

Hello,

How do i change the marker size for the pzplot ?

Best Answer

h=tf(1,[1 1 5])
pzplot(h)
findobj(gca,'type','line')
set(a(2),'markersize',7)
set(a(3),'markersize',7)

MATLAB: I am using pole-zero map (pzmap) and i want to enhance the size of pole or zero (or in other words i want to change the marker size). Please guide me how can i do by coding

It is not obvious, and requires some experience with ‘handle diving’ into graphics objects.

Try this:

H = tf([2 5 1],[1 3 5]);                    % Define System
pzmap(H)                                    % Create Plot
hm = findobj(gca, 'Type', 'Line');          % Handle To 'Line' Objects
hm(2).MarkerSize = 20;                      % ‘Zero’ Marker
hm(3).MarkerSize = 20;                      % ‘Pole’ Marker

This changes them from their default size of 7 to 20.

EDIT — This works in R2018b. I cannot test it with earlier releases.

MATLAB: Pzmap vs pzplot vs zplane

The pzmap and pzplot funcitons are part of the Control System Toolbox (and associated Toolboxes), with pzplot being an extended version of pzmap with more plot options. Both can handle either continuous or discrete systems.

The zplane function is part of the Signal Processing Toolbox and presents similar information, however in a completely different context and a completely different syntax. It can only handle discrete transfer functions.
