Follow-up Comment #6, bug #43895 (project octave):
Could somebody with access to Matlab run the following and report the
results.
[a,b] = freqz (1, [1, -0.5, 0.8], 10)
@Doug: using your patch this returns an 11-point vector whereas the
documentation seems to imply this should return a 10-point vector (same as n).
I think instead of changing the value of 'n' we want to change the spacing of
Fs.
The code change below works to return a 10-point vector and display everything
out to a normalized frequency of 1.0.
- f = Fs * (0:n-1).' / N;
+ f = Fs * linspace (0, n, n).' / N;
