Hi,
     I've put together some code to allow octave to access the
FFTW library (a fast (GPL'd) fft lib ---> www.fftw.org).  The code
is based pretty closely on the original fft code from octave and
gives a significant speed improvement.

I decided not to post the code directly to the list but if anyone is
interested I'll pass
it on.  It will probably need some (a lot) fixing but is currently usable
for 1D and 2D 
complex ffts.

cheers

Hayden
