plot the zero pole map of a given transfer function in matlab

To plot the zero-pole map of a transfer function in MATLAB, you can use the "pzmap" function from the Control System Toolbox. Here's an example of how to do it:

main.m
% Define the transfer function
s = tf('s');
G = (s + 1) / (s^2 + 3*s + 2);

% Plot the zero-pole map
pzmap(G);

In this example, the transfer function G is defined as (s + 1) / (s^2 + 3s + 2). The "pzmap" function is then used to plot the zero-pole map of G.

The resulting plot will show the locations of the poles and zeros in the complex plane. The poles are indicated by 'x' markers, while the zeros are indicated by 'o' markers. The plot also includes the origin (0,0) to help with visualization.

You can customize the plot further by changing the marker style and color, adding labels, etc. For more information about the "pzmap" function and its options, you can refer to the MATLAB documentation.
