Bug 575423 says the fft routines in Maxima are broken. Indeed, they
are because the actual FFT rotuines are not included. I've ported
over my Lisp FFT routines and included them.
However, I have no idea how to test this. I've been unable to create
an array that is acceptable to the fft routines. I tried
array(ar,4), arraymake(ar,[4]), and make_array. The resulting arrays
are rejected by fft.
Can someone supply me an example here?
Thanks,
Ray
