still superior to the Cooley-Tukey method, even when working with a larger grid. We’ll show why that is below. Computing a “large” discrete Fourier transform from a “small” one: extending the Cooley-Tukey FFT To summarise the above, the Cooley-Tukey Fast Fourier Transform (FFT) is an algorithm used
