LA BOUCLE OUVERTE DE LA MADA CONTROLE INDIRECT

matlab的一个基于realadaboost的人脸检测程序，有详细的源码，包括haar特征的提取，以及若分类器的学习。(Matlab based on adaboost face detection procedures, there are detailed source code, including haar feature extraction, and if the classifier learning)

chebyshev pade 逼近，采用了chebyshev多项式(chebyshev pade approximation, using the chebyshev polynomial)

学校做的项目源码，运用粒子群算法求解矩阵特征值。粒子群算法注释比较详细，想研究粒子群的同学可以借鉴看看。(Schools do the project source code, the use of particle swarm algorithm for solving matrix eigenvalues. Particle Swarm comment in more detail, the students want to study particle swarm can learn to see.)

matlab教程R2010a书上程序，自己按照书上编写的，很有用(tutorial matlab R2010a program book)

说明：  程序使用说明： 1、软件应用平台：Matlab6.5或更高； 2、打开方法： 将文件所在目录设为工作目录，然后打开wavlet.fig,在noise提示框下输入噪声强度，在0-0.1之间（不能为零）。 然后点process按钮，就会显示实验结果，包括原图像，加噪图像，去噪图像的对比以及当前的psnr值。 wavlet.m是程序文件。 程序内容写在在程序的注释里。 阈值的更改没有实现可视化，在源程序中可以改。(Procedure for use: 1, Software Platform: Matlab6.5 or higher 2, open the way: the file directory set the working directory, then open the wavlet.fig, the noise boxes, enter the noise level, in the 0-0.1 between (not zero). Then process the button, it will show the experimental results, including the original image, noise image denoising image contrast and the current psnr value. wavlet.m is the program file. Program content in the program notes written inside. Threshold changes are not visualized in the source program can be changed.)

这是我多年MATLAB编程的技巧汇总，希望对大家有用。里面包含命名规则，怎样优化程序等等。(This is my years of MATLAB programming skills summary, I hope useful for everyone. Which contains the naming rules, how to optimize procedures.)
