this is the security code to maintain the factor of security

这是matlab的高级编程，适合于已经熟练掌握的专业人士(This is a matlab advanced programming, suitable for professionals have mastered)

在遇到一系列线性方程的时候 构造等式约束矩阵和不等式约束矩阵解线性规划(Solving linear programming)

Dean 的PLL Performance,Simulation and Design 这本书里2nd 滤波器PLL求解的matlab程序(Dean of the PLL Performance, Simulation and Design This book 2nd PLL filter matlab program to solve the)

NSGA-II源程序,用于求解多目标优化问题，是对NSGA在非支配集构造方法，维持解分布性策略等方面进行的改进。(NSGA-II source code for multi-objective optimization problem, NSGA is a non-dominated set in the constructor, maintenance solutions and other aspects of the distribution strategy of improvement.)

K均值有效执行++多元数据的聚类算法。它已经表明，该算法具有的总群集内距离的期望值是日志（K）的竞争力的上限。此外，K -均值++通常远高于香草收敛K均值少。(An efficient implementation of the k-means++ algorithm for clustering multivariate data. It has been shown that this algorithm has an upper bound for the expected value of the total intra-cluster distance which is log(k) competitive. Additionally, k-means++ usually converges in far fewer than vanilla k-means.)

本算法结合小波变换和SVD奇异值变换，实现了水印的嵌入和提取，载体图像的鲁棒性和水印的不可见性，提取出的水印图像的和原水印图像基本一致，抗攻击性强。(The algorithm combines wavelet transform and SVD singular value transformation, achieved watermark embedding and extraction, vector image watermark robustness and invisibility, the extracted watermark image and the original watermark image are basically the same, anti-attack and strong.)
