这是一个非常适合初学者的Matlab教程，里面讲的东西简洁明了，而且可以作为教学用。(This is a tutorial for beginners in Matlab, which was about things concise, and can be used as a teaching.)

compression and decompression for image

对图像从上到小进行扫描，稍微修改下，也可以左右扫描(The image is scanned from top to small, slightly modified, they can scan around)

matlab绘图教程（1、 学习MATLAB的各种二维绘图； 2、 学习MATLAB的三维绘图； 3、 MATLAB的绘图修饰； 4、 基本句柄绘图操作。 ）(Matlab Mapping Guide (1, the study of two-dimensional MATLAB graphics; 2. Learning MATLAB 3D graphics; 3, MATLAB graphics modification; 4. Mapping handle basic operations.))

PCA用于组成分分析，在labview下编程的，对于初学PCA有一定的帮助(PCA analysis labview)

提供一种求解最优哈密尔顿的算法---三边交换调整法，要求在运行jiaohuan3（三交换法）之前，给定邻接矩阵C和节点个数N，结果路径存放于R中。 bianquan.m文件给出了一个参数实例，可在命令窗口中输入bianquan,得到邻接矩阵C和节点个数N以及一个任意给出的路径R,，回车后再输入jiaohuan3,得到了最优解。 由于没有经过大量的实验，又是近似算法，对于网络比较复杂的情况，可以尝试多运行几次jiaohuan3,看是否能到进一步的优化结果。 (Provide an optimal algorithm Hamilton- trilateral exchange Adjustment Act, requiring running jiaohuan3 (c exchange) before a given adjacency matrix C and the node number N, the results of the path stored in the R in. bianquan.m document gives examples of a parameter can be in the command window, type bianquan, be the adjacency matrix C and the node number N and an arbitrary given path R,, carriage return after the input jiaohuan3, have been the optimal solution . After the absence of a large number of experiments, it is approximate algorithm, for more complex network situations, you can try to run several jiaohuan3, can look to further optimize the results.)

matlab 主成分分析法程序，以目标威胁度评估为例(matlab principal component analysis procedures in order to target the threat assessment as an example)

用elliptic 函数 来求解系统频率，通过matlab(elliptical function to disolve the frequency of system with matlab)

说明：  ＬＥＡＣＨ算法ＭＡＴＬＡＢ源代码，适合研究使用(LEACH algorithm matlab source code, suitable for research and use)
