用matlab做的多元线形回归预测的小程序，抱愧数据，可以运行。(using Matlab do multiple linear regression forecast a small procedure, feel ashamed of data, can run.)

matlab 学习技巧，现在把我用的，也就是对我帮助很大的留个文件传上去，希望对大家有用，第一应用与技巧(matlab learning skills, and now I use, which is a great help to me to leave a document passed up, we want to be useful, the first application and skill)

说明：  灰色GM(1,1)和DGM源代码，功能齐全，各种显示内容均添加(Grey GM (1,1) source code, complete functions, various displays are added)

随便编写的，我刚学matlab图像处理，这是我的学习程序(Just write, I just learning matlab image processing, this is my learning process)

Cauchy probability distribution function sample

MATLAB function that performers delay and sum beamforming on two input signals in the frequency domain.

用Matlab对图像进行哈夫曼编码（Huffman Coding）以实现对图像的无损压缩(Use Matlab to realize Huffman coding for lossless image compression)

程序均用matlab编写 ch ex 的文件是信号与系统频谱密度函数或者时移特性的展示 Advanced_Mathematica_picture_zoom是利用二次线性内插值法对彩色图片进行任意倍数的放大 每个程序都含有详细的注释(Programs are written in matlab chex file is spectrum density of signal and system function or moving features of the display Advanced_Mathematica_picture_zoom using quadratic linear interpolation method in arbitrary multiple amplification was carried out on the color images Every program contains detailed annotations)

两层复杂网络Laplacian矩阵的构造与特征值分析(Multiple Network Laplacian Spectra)

adboost算法的一个例子。在Kearns和Valiant在1989年大作中指出了这种算法的可行性。而后，Freund在 1990年以及他和Schapire在 1994-1996年提出了boosting整个算法思路，似乎这种算法走到 了实际应用的开端。然而直到AdaBoost被viola在其人脸识别系统中运用(2001Viola和 Jones)，这种方法才彻底开始暴火.(An example adboost algorithm. Kearns and Valiant pointed at the feasibility of this method in 1989 masterpiece. Then, Freund and Schapire he made in 1990 and in 1994-1996 the idea of ​ ​ boosting the entire algorithm, this algorithm seems to come to the beginning of the practical application. However, until the use of AdaBoost is viola (2001Viola and Jones) in its face recognition systems, this approach was completely start a fire storm.)
