That depends on the type of license you have.
What sort of license do you have? Are you using MATLAB as part of a university license or a personal license?

Just a question is It normal to have a transfer function like this ?
It's definied by :
Real(TF(v)) = cos(2*pi*v).
and phase is 0.
I thing that the parameter s=j*w.
So is It normal to have a real part like this? ( parameter in the cosine)
and how to get transfert function from real and image parts.

Hi,
If you have the licensed product “Control Systems Toolbox”, but have not installed yet, you can do as follows:
  • Go to MATLAB - > HOME -> Add-Ons -> Get Add-ons -> search for “Control Systems Toolbox” -> click Install
If you do not have the product, then
For any support regarding purchase or License contact the sales team:
