It apparently has to be in the form of 
. I could not get there when I tried it.
. I could not get there when I tried it. Also, the trigonometric argument has to be 
.
. If you want to include sampling time T (which is assumed to be 1 by default), you can add it into the function.
If you want to be in the form of z^-1, you just need to devide z^2 from both numerator and denominator.
syms n omega f(n) T
f(n) = sin(omega*T*n)
ztrans(f(n))

If you "doc ztrans", you will find that matlab performs z-transform for n=0, 1, ... by its definition
