说明：  图片识别，识别任意图片中的汉字，字符灯内容，保存为c文件，可以用做多种用途(Picture recognition, recognition of Chinese characters in any picture, character lamp content, saved as C file, can be used for a variety of purposes.)

C# CS结构发消息聊天模块，服务端和客户端同时运行，可简单互通消息，实现类似点对点聊天的功能，测试前请输入IP和端口号，登录功能需要服务器配合。

说明：  全球线性代数及其应用，一本非常不错的线性代数书，对我学习线性代数起到了至关重要的作用(global linear and its applications)

Android 拖动 Button 显示效果，在Android测试机上是按住鼠标拖动按钮，和其它的拖动操作方法一样，不过在手机上运行的时候，用手触摸屏幕按钮住屏幕移动，就可移动按钮，代码注释英文，来自国外Android网站的源码。

简单的蒙特卡洛算法，设计拟合随机数，通过系类操作完成部分计算-A simple Monte Carlo algorithm, designed to fit a random number, through the Department of the completion of part of the calculation of class action

Matlab通过函数imread读取RGB图像，并通过维数m*n*3的矩阵来表示。其中，维数mn表示图像的行数列数信息，维数3表示图像的RGB三层通道数据。因此，全局直方图处理通过对RGB图像的RGB三通道分别进行直方图均衡化，再整合到新的图像的方式进行。(Matlab reads the RGB image through the function imread and is represented by the matrix of the dimension m*n*3. Among them, the dimension mn represents the row sequence information of the image, and the dimension 3 represents the RGB three-layer channel data of the image. Therefore, the global histogram processing is carried out by equalizing the RGB three channels of the RGB image and integrating them into the new image.)
