Jury table

Hi guys,

I am doing this project purely out of interest (not as a homework) The gist is to take a transfer function and test the stability of it with the Jury table.

I was told to take the denominator and declare it as a vector so that I can use the coeffs. I have been told to use [numz, denz] to extract the coeffs. but I do not know how...

Any kind soul out there?
