Confirmed, thanks for testing and reporting. It seems to only use the number of points of the input array rather than the actual frequencies given.

I am using signal-1.3.2. The Octave code
behaves as expected from the help description. wp=w(1:128).

The Octave code
does not behave as expected. Tp is calculated over 128 points across [0,pi] (where pi corresponds to Fs/2). I expected 128 points across [0,pi/2]. In addition, wp is scaled strangely.
