You can integrate in the frequency domain by dividing the
complex FFT by iw.  I've been trying this but to no avail
since I seem to be getting hung up on the symmetry of the
FFT around the nyquist.

For example:

x = 1:10;

and the integral of x is trivial.

But I try to do this via fft, division by iw and then
inverse fft and end up with junk.   I recall seeing this
done someplace before but I checked the archives and found
nothing.

Can anybody show how this is done!
