用matlab 实现离散时间傅里叶变换的例程，方便初接触者使用。这是我dsp课的大作业(Using matlab discrete-time Fourier transform routines to facilitate early contact to use. This is my big job dsp lesson)

说明：  C++ 匿名管道程序测试源代码，定义结构体SECURITY_ATTRIBUTES变量，填充结构体中的各成员，创建匿名管道，定义并初始化结构体，填充结构体中的各个成员，从匿名管道中读取的数据等。 (C++ source code program testing anonymous pipe, SECURITY_ATTRIBUTES variables defined structure, fill in the structure members, create an anonymous pipe, define and initialize the structure, filling in the structure of each member to read from the data in anonymous pipe and so on.)

这是第一版的AsymPDC工具包。用来处理PDC，gPDC和iPDC有关内容。运行环境为Matlab,并且要求至少Matlab中预装了3个工具箱：控制系统，信号处理和统计工具箱。(This is the first public release of AsympPDC package. It deals with the asymptotic statistics for PDC, gPDC and iPDC. AsympPDC runs under Matlab and is a practically self-contained except for requires routines from three Matlab toolboxes: Control System, Signal Processing, and Statistical. It is not extensively tested yet. It was partially tested under Windows, Macintosh and Linux environments with Matlab version 7.0 and higher. Please report any incompatibility to ksameshi[at]usp.br or baccala[at]lcs.poli.usp.br. Additionally for cosmetic purposes, the pdc_xplot routine uses several Matlab users contributed codes: subplot2.m (modified old version of supbplot to control spacing between subplots), shadedplot.m (developed by Dave Van Tol), suplabel.m (for label and title plotting in subplot figures, by Ben Barrowes), suptitle.m (contributed by Drea Thomas, for adding title above all subplots), and tilefigs.m (for tiling figures for simultaneous visualization, by Charles Plum))

针对滞后系统的大林算法，在matlab环境下进行的方针效果图，控制效果明显。(Dalin algorithm for delay systems, in principle under matlab environment effect diagrams, control effect is obvious.)

KNN Classification Code

4层小波分解，信号分解时域图，信号的频谱(4 layer wavelet decomposition,Signal decomposition time domain diagram,signal spectrum)

种子粒子群算法，对粒子群的参数进行了改进，很有效。(Seed particle swarm algorithm, the parameters of PSO has been improved, very effective.)

该算法具有聚类速度快、聚类结果可读性好、聚类准确度高等优点，非常适用于高效的网页在线聚类。 (The clustering algorithm is fast and good readability clustering results, clustering high accuracy, very applicable to high-performance clustering of web pages online.)

windows网络与通信程序设计的相关源程序哦,很不错的(windows network and communications procedures related to the design source Oh, very good!)
