I'm trying to input this transfer function in matlab, but I can't figure out how because it has both positive and negative exponents.
If I do H = tf([1],[1 1 1 1],0.1,'variable','z^-1') I almost get it, but I can't figure out how to add the positive z to the bottom. I'm trying to use this H to plot the poles and zeros with pzmap(H).
