fft

One-dimensional fast Fourier transform

C++ Prototype

mwArray fft(const mwArray &X);
mwArray fft(const mwArray &X, const mwArray &n);
mwArray fft(const mwArray &X, const mwArray &n, const mwArray &dim);

C++ Syntax

#include "matlab.hpp"

mwArray X, n, dim;          // Input argument(s)
mwArray Y;                  // Return value

Y = fft(X);
Y = fft(X,n);
Y = fft(X,empty(),dim);
Y = fft(X,n,dim);

MATLAB Syntax

Y = fft(X)
Y = fft(X,n)
Y = fft(X,[],dim);
Y = fft(X,n,dim)
