判别稀疏非负矩阵分解，提出这个新算法，来进行人脸识别，比传统的NMF和一些其他的扩展算法效果好(Sparse non-negative matrix factorization judge proposed the new algorithm for face recognition, than the traditional extension of NMF algorithm and some other good results)

拉丁超立方抽样，调用方式如下：S=lhs(m,dist,mu,sigma,lowb,upb) m: a scalar,the number of sample points dist: A row with distribution type flags of basic random variables the value of the flag can be 1 (for uniform distribution, 2(for normal distribution), 3(for lognormal) and 4(for extreme type 1). mu: A row vector comprising the mean value of basic random variables. sigma: A row vector with its length equaligng to mu,including the standard deviation of basic random variables. lowb: a row vector with its elements are the lower bound of the sampling interval upb:a row vector with its elements are the upper bounds of the sampling interval dist,mu,sigma,lowb,upb must have the same length. Output argument S: sampling point matrix, of which each row is a sampling point.(code of Latin Hypercube Sampling)

Robust image watermarking using two level discrete wavelet transform using constant scaling factor. At the same time you can use any optimization algorithm instead of constant scaling factor.

图像处理，图像的反转的matlab例程，验证可用，请多多指教(Image processing, image reversal of matlab routines, authentication is available, please advice)

为.dat文件的每帧的帧头加上帧长等信息(for. Dat paper every frame with the header information such as frame size)

ACF中包含两个m文件，一个是自协方差函数（可单独使用）。另一个是自相关函数计算，其调用autocov函数。(ACF contains two m files, one is self-covariance function (which can be used alone). The other is calculated from the correlation function, which calls autocov function.)

关于开环系统的分析 包括奈奎斯特图和伯德图，以及对系统进行校正前后的分析(With regard to the analysis of open-loop system, including the Nyquist diagram and Bode plot, as well as an analysis of the system before and after correction)
