[Octave-bug-tracker] [bug #64374] [ocatve forge] (control) tf not working for descrete z transform

[Doug Stewart]

Follow-up Comment #1, bug #64374 (project octave):

works for me on octave 7.3


>> z = tf ('z', 0.2);
>> H = 0.095/(z-0.9)

Transfer function 'H' from input 'u1' to output ...

       0.095
 y1:  -------
      z - 0.9

Sampling time: 0.2 s
Discrete-time model.
>>  z = tf("z", 0.1)

Transfer function 'z' from input 'u1' to output ...

 y1:  z

Sampling time: 0.1 s
Discrete-time model.
>> H = 0.095/(z - 0.8)

Transfer function 'H' from input 'u1' to output ...

       0.095
 y1:  -------
      z - 0.8

Sampling time: 0.1 s
Discrete-time model.
