Cfftn matlab
WebJan 1, 2013 · As I know Matlab provides built in function fft which computes DFT and probably it is possible to convert results from DFT to DTFT. I found function that get DTFT using fft inside. function [H, W] = dtft(h, N) %DTFT calculate DTFT at N equally spaced frequencies %---- % Usage: [H, W] = dtft(h, N) % % h : finite-length input vector, whose … Webfftn (X) is equivalent to. Y = X; for p = 1:length (size (X)) Y = fft (Y, [],p); end. This computes in-place the one-dimensional fast Fourier transform along each dimension of X. The …
