Why use fftshift(fft(fftshift(x))) in matlab instead of fft(x)?

The following Matlab project contains the source code and Matlab examples used for why use fftshift(fft(fftshift(x))) in matlab instead of fft(x)?. Explain why we use fftshift(fft(fftshift(x))) in Matlab instead of fft(x). An example is given. The example and Matlab codes are partially copied from Daniele Disco ‘s work in "A guide to the Fast Fourier Transform, 2nd Edition".

The source code and files included in this project are listed in the project files section, please make sure whether the listed source code meet your needs there.
