Matlab Z transform coefficient extraction

Hi I have a z transform function 3/z + 5/z^2 + 6/z^3 + 1

How would I extract the coefficients from this equation? I have tried using coeffs and it says it is not a polynomial.

I would like the answer to come out as [3 5 6 1]

You can create a different variable x=1/z and find the coefficients of the polynomial 3x+5x^2+gx^3+1:

syms x
coeffs(subs(3/z+5/z^2+6/z^3+1,z,1/x))
