Follow-up Comment #2, bug #60423 (project octave):
Thank you Wc_s is the value.
This octave function has more output options available, which is good.
The documentation states
Wc_p (Wc_n) is the value used to pass to butter.
Using the same source there is a test
[n,Wn]=buttord(wp,ws,Rp,Rs);
[B,A]=butter(N,Wn);
In this case wc_p would be used? Not sure how to make this more clear.
If you like this bug could be closed.
-----------
This IEEE source looks good for adding BIST (buttap, cheb1ap, zp2tf, etc).
The next test fails (p values in wrong order)
Would you like new bugs/patches for each of these? Or just add to this one?
