Reorganizing 2D FFT for Conventional Viewing [?] [message #4473] Wed, 21 June 1995 00:00

I'm trying to rearrange the 2D FFT so that zero frq is in the middle,
and all other frqs end up in the right place. Using the Fourier shift
theorem prior to transforming does work, but it really slows things down!
Doing lots of loops to simply rearrange the final array takes a while
too, and it doesn't look very nice....
Any _elegant_ (fast) ways of doing this?

Thanks :-)
