This shows how to process a signal with an odd and even length fft. The magnitude, phase, and corresponding frequency vector are calculated. This is a quick reference for the next time I want to do these calculations. Applications include frequency analysis of signals, Short Time Fourier Transform (STFT), ideal filtering (combined with symmetric ifft), and probably some other applications.
