Hi there,
I have modeled a transfer function in Simulink. How can I get the bode plot of the model using Matlab code? I don't want to use the model linearizer in the apps.
Thanks

Hi @Mahdi Zolfaghari
This is an example to get the Bode plot with MATLAB code:
Gp = tf([1 3], [1 2 3 0])
Gp = s + 3 ----------------- s^3 + 2 s^2 + 3 s Continuous-time transfer function.
bode(Gp)
margin(Gp) % if you want to display the stability margins
