Y = 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 columns of X as vectors and returns the Fourier transform of each column.

Webis a MATLAB toolbox – modeled after commercial toolboxes. Functionally, it becomes a part of the MATLAB toolbox set so that AT functions can reuse tools from other toolboxes, for instance optimization and control. AT is an open-ended collection of tools – MATLAB functions and scripts arranged in functional groups as opposed to one giant engine. WebOutput is complex. Symmetry type 'symmetric' is not supported..
