It was (and has the potential to be) a real gem for engineers such as myself
for testing DSP filter implementations. However, I suppose that is a niche
community and the octave-fixed package has fallen by the wayside.
While I am a, perhaps, reasonable C programmer, having looked at the code I
don't think I have the skillset to update the package so that it can be
built for current Octave. It probably needs some good knowledge of
If someone was willing to assess the work involved and estimate a cost we
could perhaps make an arrangement to bring this package up to date.
