采用离散傅立叶变换实现的低通滤波器，希望对你们有用，MATLAB实现-discrete Fourier transform of the low-pass filter, and I hope to you useful MATLAB

详细表述了分数阶傅立叶变换的离散实现，将现有的算法进行比较。-In this note we make a critical comparison of some matlab programs for the digital computation of the fractional Fourier transform that are freely available and we describe our own implementation that lters the bes

离散傅里叶变换的子程序，matlab的built in函数的一部分程序-Discrete Fourier Transform subroutine built in matlab function part of the program

The low-pass filter is realized by using discrete Fourier transform, hope useful to you, MATLAB
