Radix-2 Fast Fourier Transform
The package performs the radix-2 FFT of a real or complex sequence, or sin/cos/complex Fourier integral of an evenly tabulated function. The input can be either real or complex with/without zero padding; you can request either the full complex transform, or only real/im/abs part of it. The archive contains a commented C++ source code to build the library, plus a test driver to test and show off all possible usages (on real examples), and test run outputs.
