%FFTN N-dimensional discrete Fourier Transform.
%   Y = FFTN(X) returns the N-dimensional discrete Fourier transform
%   of gpuArray X.  If X is a vector, the output will have
%   the same orientation.
%   
%   Y = FFTN(X, SIZ) pads or crops X to size SIZ before performing 
%   the transform.
%   
%   Class support for input X: 
%     float: double, single 
%     integer: int8, uint8, int16, uint16, int32, uint32
%     logical
%   
%   The output Y is always complex even if all imaginary parts are zero.
%   
%   Example:
%    
%       N = 64;
%       X = gpuArray.rand(N, N, N);
%       Y = fftn(X);
%
