Blitz Support : |

Hi All,
Thanks for all the comments regarding FFT support for Blitz. I agree that
we don't want to be writing new routines from scratch when many good ones
already exist. FFTW does seem to be the best all-around package out there.
Obviously, it is not difficult to use the existing blitz Array interface to
pass Array data to FFTW routines directly and invoke the transforms. But it
might be nice to add a blitz interface that does this for you.
Todd, can you shed any light on the licensing issue? I think GPL allows us
to package a copy of the FFTW source along with blitz if we want, as long as
the GPL license remains intact with the software. But perhaps we should
just make this an installation option for the user to download and install
FFTW separately for FFT capability. In any case, this should be a
low-priority item, since one can use FFTW with blitz already.
Regards, Julian C.
