Dwf and fft
WebJul 12, 2010 · When you understand the DFT then move on to the FFT. Note that although the general principle is the same, there are many different implementations and variations of the FFT, e.g. decimation-in-time v decimation-in-frequency, radix 2 v other radices and mixed radix, complex-to-complex v real-to-complex, etc. WebY = fft(X) computes the discrete Fourier transform (DFT) of X using a fast Fourier transform (FFT) algorithm. If X is a vector, then fft(X) returns the Fourier transform of the vector. If X is a matrix, then fft(X) treats the …
