I'm tryng to implement a control system method in matlab but I have a problem in plotting a curve so I don't find a solution to compute the absolute value of a tranfer function declared with the classical command "tf". The function "abs()" is not useful so I ask you which the way to solve the problem. Thank you so much.

Example
N=1;
D=[1 10]
model=tf(N,D) % your transfer function
Now what do you mean by: An absolute value of a transfer function

It's not f=P1/(1-P1) but
f=P1./(1-P1)
plot(w,f)

Hey Graz.
I can see the post belongs to long ago. But did you ever find the answer to this question? I'm trying to plot the exact same transfer function for an Audio application.
