I need a fast and reliable FFT algorithm in C++. I found a C algorithm
on the webseite http://www.fftw.org/index.html (FFTW).
But I am stuck at the point howto actually use the algortihm and comile
it myself.
I would be gratefull if somebody could point me to some website with
further information or give me a short introduction.
Other FFT algorithms are welcome as well.
