传统的pca人脸识别中的matlab算法，人脸前期处理，希望对大家有用( I was born in Liaoning.Liaoning is a beautiful place.There are many places of interest in Liaoning.I was born on September,26th.I am a girl.I like traveling,reading and English.Speaking English is very important.It s very useful for us.We should do our best to learn English.I like making friends,too.I want to make more and more friends.Let s be friends.When I am free,I usually read books.Much of my life has lived with books.My favorite book is《Harry Potter》.Harry Potter is a brave,clever boy.I like him very much.Books are very interesting.I have great fun in reading books. )

傅里叶描述子用来描述和识别图像中有边缘的物体形状，本程序基于MATLAB，测试可用(Fourier descriptor is to analyze and identify the important objects in the shape of one of the methods. The use of polygon-based curve near Continuous Fourier transform method like Fourier descriptors, and through the main direction of the shape to eliminate the border from Phase of the influence of starting point, define a new rotation, translation and scale invariance of the normalized Fourier Ye descriptor.)

实时语音降噪的资料包，自己正在研究设计一个语音处理软件，等完成后传上来分享。(Real-time voice and noise reduction package, he is studying the design of a voice processing software to pass up and so finished sharing.)

DCT 3D function for signal

此程序能够实现在matlab中对信号的小波包分析。(This procedure can be achieved in matlab signal using wavelet packet analysis.)

关于无约束的一维极值的最优化matlab算法，包括斐波那契法，割线法，黄金分割法，三次插值法，进退法，newton法，抛物线法，Goidstein法，wolfe.powell法，代码里有注释表明是哪种方法，

Lsqcurvefit-Torque，最小二乘法曲线拟合，主要用于发动机负荷曲线的拟合工作。(Lsqcurvefit-Torque, least squares curve fitting, mainly for the engine work load curve fitting.)

yahoo股票历史数据下载器器，matlab编写可直接使用。 (yahoo stock historical data downloader, matlab prepared for immediate use.)

此方法是层析分析法的一个较好的程序，可以用于数学建模竞赛等领域。是不错的收藏啊啊啊啊(This method is a better program, chromatography analysis can be used in areas such as Mathematical Contest in Modeling. Good collection ah ah ah ah)
