Hello. Change i it correctly?
0.0004773 (z+0.9544)
---------------------
(z-0.9591) (z-0.9064)
to
0.0004773z^-1 (1+0.9544z^-1)
---------------------
(1-0.9591z^-1) (1-0.9064z^-1)

z = zpk('z',-1);
H = 0.0004773 * (z+0.9544)/ (z-0.9591) / (z-0.9064)
H.Variable = 'z^-1'

z = tf('z');
Gz = 0.0004773*(z+0.9544) / ((z-0.9591)* (z-0.9064))
Gz1 = tf(Gz.Numer, Gz.Denom, Gz.Ts, 'Variable', 'z^-1')
