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. )

粒子群算法优化支持向量机参数，可用于分类(pso svm)

matlab产生均匀 高斯 锐利等分布并画出直方图(using matlab to get random)

说明：  LFM雷达信号处理，FFT信号处理，脉冲积累。(LFM radar signal processing, FFT signal processing, pulse accumulation.)

产生有色噪声污染的谐波，并设计带通巴特沃斯滤波器和切比雪夫I型滤波器(Colored noise pollution generated harmonics, and to design band-pass Butterworth filter and Chebyshev-I filter)

用MATLBA实现聚类，简单好用，适合初学者(Clustering in with MATLBA, easy to use, suitable for beginners)

因为MATLAB需要用到处理器的数学运算部分(MATLAB默认用的是INTEL的数学处理单元),故需要设置一下BLAS(Basic Linear Algebra Subroutines,就是"基础线性几何子程序"的意思)环境变量. 首先请确认你的MATLAB的文件夹中有如下文件:atlas_Athlon.dll(AMD系列的请用这个)， atlas_P4.dll(P4的用这个)，atlas_PIII.dll(P3的用这个)，atlas_PII.dll(P2的用这个)，这些是对应处理器的数值运算优化文件 } 先找到 $MATLAB7inwin32目录下的atlas_Athlon.dll（AMD系列CPU使用）和atlas_P4.dll（奔4用）文件，放到MCR目录中（随便），然后设置环境变量 变量名：BLAS_VERSION 变量值：D:MCRv70atlas_Athlon.dll(Because the MATLAB mathematical operations need to use some of the processor (MATLAB is used by default INTEL mathematical processing unit), so you need to set BLAS (Basic Linear Algebra Subroutines, is " based on linear geometry subroutine" means) environment variable. First make sure your MATLAB folder the following files: atlas_Athlon.dll (AMD series please use this), atlas_P4.dll (P4' s with this), atlas_PIII.dll (P3' s use this), atlas_PII.dll ( P2, use this), these are the values corresponding to processor operations to optimize file} first find $ MATLAB7 bin win32 directory atlas_Athlon.dll (AMD series CPU use) and atlas_P4.dll (Pentium 4 with) file, put MCR directory (random), and then set the environment variable variable name: BLAS_VERSION variable value: D: MCR v70 atlas_Athlon.dll)
