在MATLAB里，基于dct域,实现在二维图像中嵌入数字水印 并提取。(In MATLAB, the dct-based domain, the realization of two-dimensional images in the digital watermark embedding and extraction.)

matlab,simulink视频4，5,接着上次传得视频(the vidio of matlab)

该程序是使用Matlab仿真协同通信的DF（解码转发）基本性能，基本模型S-R-D三个节点，接收端使用MRC（最大比合并）。固定DF由于SR信道的错误，其性能受到限制，在大SNR情况下不能获得有效分集。而当SR距离足够近的时候，可能获得一定的分集增益。(The program is a cooperative communication using Matlab simulation DF (decode forwarding) basic performance, the basic model of the SRD three nodes, the receiver uses the MRC (maximum ratio combining). Fixed DF error of the SR channel, its performance is limited, can not obtain a valid diversity in the large SNR case. When the SR close enough, you may get some diversity gain.)

产生图像的纹理信息，包括平均亮度，熵，三阶矩，一致性。。。(Generating texture of the image information, including an average brightness, entropy, the third moment, consistency. . .)

多尺度熵，用于对图像和各类数字信号进行处理(multiscale entropy used for the signal processing)

此代码为《无网格法》书籍的Matlab源码，作者是张雄。(This code is "meshless method" Matlab source books, the author is Zhang Xiong.)

维基尼亚密码的matlab程序，解压m文件放在matlab工程目录即可！(matlab code for vigenere cipher)

在matlab中 HSV各分量求均值 方差以及三阶矩(Color extraction)

采用加权网络中节点强度和权重都是幂率分布的模型，可以广泛的应用于数据预测及数据分析,用MATLAB实现动态聚类或迭代自组织数据分析。( Using weighted model nodes in the network strength and weight are power law distribution, Can be widely used in data analysis and forecast data, Using MATLAB dynamic clustering or iterative self-organizing data analysis.)
