Bode diagram : Warning: Error occurred while evaluating listener callback.

I wrote the following code, I am gettign this error:

Warning: Error occurred while evaluating listener callback.

Here is the code:

w_0 = 100
D = 10
K = 26.5;
s = tf('s');
G = w_0/(s^2 + 2*D*w_0*s + w_0^2)
bode(G)
%pole(G)
%pzmap(G)

grid on
hold on
margin(K*G);
legend('Open-loop','Open-loop with gain K')
hold off

I would be greatful for any feedback!

Your code runs without error in R2023a.

Perhaps an upgrade is in order —

w_0 = 100;
D = 10;
K = 26.5;
s = tf('s');
G = w_0/(s^2 + 2*D*w_0*s + w_0^2)

G =
 
          100
  --------------------
  s^2 + 2000 s + 10000
 
Continuous-time transfer function.

bode(G)
%pole(G)
%pzmap(G)

grid on
hold on
margin(K*G);
legend('Open-loop','Open-loop with gain K')
hold off

.

I am using MATLAB R2020a

what should I change in order for it to work.

[Star Strider]

Be sure all the updates to R2020a are installed, since they may have fixed that particular problem.

If there are still problems after that, it may be necessary to upgrade to a more recent version/release.
