Description: Basically, this article describes one way to implement the 1D version of the FFT algorithm for an array of complex samples. The intention of this article is to show an efficient and fast FFT algorithm that can easily be modified according to the needs of the user. I ve studied the FFT algorithm when I was developing a software to make frequency analysis on a sample of captured sound.-Basically, this article describes one way to implement the 1D version of the FFT algorithm for an array of co mplex samples.

Description: 离散傅里叶变换是20世纪60年代是计算复杂性研究的主要里程碑之一，1965年Cooley和Tukey所研究的计算离散傅里叶变换(Discrete Fourier Test)的快速傅氏变换(FFT)将计算量从О(n2)下降至О(nlogn)，推进了FFT更深层、更广法的研究与应用。
这是一个傅氏变换的MPI程序，用C语言实现。-Discrete Fourier Transform of the 20th century 60 s computational complexity is a major milestone in one study, in 1965 Cooley and Tukey studied the calculation of discrete Fourier transform (Discrete Fourier Test) fast Fourier transform (FFT) calculation increased from О (n2) dropped to О (nlogn), the FFT to promote deeper, broader research and application of law. This is a Fourier transform of the MPI process, with C language.

Description: FFT算法的基本原理是把长序列的DFT逐次分解为较短序列的DFT.按照抽取方式的不同可分为DIT-FFT(按时间抽取)和DIF-FFT(按频率抽取)算法.按照蝶形运算的构成不同可分为基2、基4、基8以及任意因子(2n,n为大于1的整数),基2、基4算法较为常-The FFT algorithm s basic principle is decomposes gradually long sequence DFT into short sequence DFT. different may divide into according to the extraction way DIT-FFT (according to time extraction) and DIF-FFT (according to frequency extraction) the algorithm. Different may divide into the base 2, base 4, bases according to the butterfly-shaped operation s constitution 8 as well as the random factor (2n, n is bigger than 1 integer), the base 2, base 4 algorithms are more common.
