GApso2011 仿真与比较，matlab语言开发的，请大家使用！！(GApso2011 simulation and comparison, matlab language development, please use! !)

principal component analysis (PCA ) is a well known approach for dimensionality reduction of the feature space. It has been successfully applied in face recognition. The main idea is to decompose face images into a small set of feature images called eigenfaces, which can be considered as points in a linear subspace called “face space” or “eigenspace”

通过使用matlab，对层次分析法进行求解，从而进一步确定权重，更快的解决问题。(By using matlab, the analytic hierarchy process (AHP) is solved to further determine the weight and solve the problem more quickly.)

中值滤波和均值滤波程序，经常用于数字图像处理中，是基本的图像预处理程序(medium filter and average filter program,it is often used in image progress )

MATLAB逐步搜索法计算方程的根. 逐步搜索法也称试算法.它是求方程f(x)=0的根的近似值位置的一种常用的方法. 逐 步搜索法依赖于寻找连续函数)f(x)满足f(a)与f(b)异号的区间[a,b]一旦找到区间，无 论区间多大，通过某种方法总会找到一个根。(MATLAB root search method gradually equation )

openExcel :用Matlab打开启动Excel服务器，并返回Excel活动页的句柄H jitt : 利用传入的周期向量，计算频率抖动 norma : 把计算得到的向量平均采样为30个点 interest ： 复利计算方法 myvad : 通常vad算法只能得到汉语普通话一声、二声和四声的语音，对于三声，中间因为有嘎裂，就是突然基频变得很低并且不规则，vad算法把一个音节往往切分为两个音节，myvad解决普通话三声的问题 (Open Excel sever by Matlab, and returen a handle of Excel active sheet)

中值滤波的matlab实现,根据K-means算法对图像进行滤波等功能(The K-means filte base on matlab.)

有向无环图程序，程序较为简洁，包含代码和简要说明。(Directed acyclic graph procedure is relatively simple, containing code and a brief description.)
