A semicolon is missing after the assignment to network.

the general case result (2) still has ztrans, it should be a simple rational function

@williamov Why do you think so?

williamov — Thu, 07 Feb 2013 17:30:30 Z

i think this because chapter 3 page 86

3.2.1 said z-transform of this network can be written as

rational function (3.1)

@williamov Can you kindly present the e-paper you referred to in MaplePrimes as an attached file?

PS. If ztrans(network, s, z); were a rational function of z in the general case, then it also were so for concrete i.

However, ztrans(network, s, z); is not a rational function of z if i=3 (see my above answer).
