%FFTN N-dimensional discrete Fourier Transform. % FFTN(X) returns the N-dimensional discrete Fourier transform % of the N-D array X. If X is a vector, the output will have % the same orientation. % % FFTN(X,SIZ) pads X so that its size vector is SIZ before % performing the transform. If any element of SIZ is smaller % than the corresponding dimension of X, then X will be cropped % in that dimension. % % See also FFT, FFT2, FFTSHIFT, FFTW, IFFT, IFFT2, IFFTN. % Copyright 1984-2005 The MathWorks, Inc. % Built-in function.
