[Octave-bug-tracker] [bug #45834] [octave forge] (signal) grpdelay with a vector of frequencies is not correct

[Mike Miller]

Update of bug #45834 (project octave):

                 Summary: [octave forge] (signal) [T,wr]=grpdelay(b,a,w) does
not use or return w => [octave forge] (signal) grpdelay with a vector of
frequencies is not correct

    _______________________________________________________

Follow-up Comment #2:

After looking at this again, the entire approach that grpdelay currently uses
requires that the frequency points be equally spaced. If the function is
called with an array of frequencies in Hz or radians, only the length of the
array is used to determine at which points to evaluate the delay.
