I all, I've to calculate AutoRegressive Model coefficients starting from zeros and poles values. There is any command that can do this? I've tried with
[b,a]=zp2tf(1,p,1);
but it seems to be uncorrect.

%example,
z=1 % one zero
p=[-1 -2], % two poles
model=tf(poly(z),poly(p))
[b,a]=tfdata(model,'v')

Thank you Azzi. I've another question: How can I do If I have to generate a signal using this AR model with White Noise as input?
