Do you need to use real FFT algorithms?
Nevertheless, don’t try to implement these algorithms, except for educational purpose. If you need to use these algorithms in practice, very efficient implementations, such as FFTW, already exists. The exception is if you are dealing with an architecture where FFTW is not available, or when the open source license of FFTW is not suitable.
