I want to plot magnitude resonse of this system
I have written the following code for this:
num = [0 2 1];
den = [1 3 2];
[h,w] = freqz(num,den);
plot(w,abs(h))
grid ON;
I got this plot:
how can I verify that this is right plot. Can anyone verify that please.

freqz only works for a discrete-time system. Your system is a continuous time. You will need to use freqresp as you did in your other question here: https://www.mathworks.com/matlabcentral/answers/630383-pole-zero-plot-and-frequancy-response-of-a-system-in-matlab
