z transforms, anybody?

John Utz-3
Hi octave people;

Has anybody out there in octave land implemented a z transform?

Also how does one do a sinc with fft? ? I tried:

octave:48> plot(arg(fft(sin(-.01:.001:.01)/(-.01:.001:.01))))
error: fft: invalid scalar argument

any suggestions?

thankyou!

OH, and is it possible to do "subplots"?   As in seeing my arg(fft and
abs(fft at the  same time?
