WebCooley–Tukey's fast Fourier transform (FFT) algorithm is a method for computing the finite Fourier transform of a series of N (complex) data points in approximately N log, N operations. FFT operates on inputs that contain an integer power of two number of samples, the input data length will be augmented by zero padding at the end. WebJan 29, 2024 · OK - I see one big problem - your data size is 201 but you're using an FFT routine which is radix-2 - you can only process FFT sizes which are powers of 2 with this function. Either: (a) make your data size, say, 256, or (b) pad your data with 0 to make it, say, size 256 or (c) use a different, mixed-radix FFT which supports arbitrary size FFTs.
