Hi, caaDespite the algorithm title, Fourier is NOT an inventor of the FFT.
This algorithm was discovered later as a "fast-computing" modification
of the original DFT formula, hence "Fourier" in it's title.

gnat,Yup, as you've pointed out, *tricks* do make life easier. And yes,
I wouldn't think Fourier would have cared if the computation is
O(n^2) or O(nlogn) as long as it's polynomially computable. But
I'm sure it's entirely different for programmers :)
