FFT

[John Biddiscombe]

>I am worried about what you say about the errors here.

Well, I wanted to

FFT(data)*Conjugate(FFT(other data))
and do a straightforward convolution. I failed to get vtk to do it in the
space of an hour or so and thought - it'd be quicker to do it myself using
other software. If you get it working, please keep me informed.
