2015年数学建模国赛A题MATLAB源代码2015A

socket控件,由vb编写实现server与client的通信-visual basic socket component, you can use this component to build a server/client communication application easily.

通过客户端与服务器端文件对比，实现自动升级功能。(Through the client and server-side document comparison, automatic update feature.)

取网络文件尺寸并进度下载易语言源码,例程结合易语言超文本浏览框支持库，使用客户组件连接文件地址，发送URL地址消息取文件的数据大小并下载，并有进度演示。(Take a network file size and schedule downloads easy language source code, combined with easy language routines hypertext browsing box support library, use the client component connection file address, data size to send a message to take the URL of the file to download, and demonstrate progress.)

一个c++ P2P聊天功能，文件传输实现代码，分为客户端和服务器端，对于新手有指导作用

由原始影像（3个波段）计算其相关系数及协方差矩阵，输入为原始图像，输出为3*3的矩阵(Calculating the correlation coefficient from the original image (3 bands))

一个简单的局域网聊天程序，delphi编写，客户端－服务器模式-a simple LAN chat program, delphi prepared, the client-server model

VC网络编程模型示例之完成例程模型(CompletionRoutine)MFC代码，配有非常非常详尽的注释，功能只是简单的显示一下各个客户端发来的字符，作为教学代码，为了使得代码结构清晰明了，简化了很多地方，用于产品开发的话还需要做很多改进，有错误或者不足的地方，非常欢迎大家不吝指出。 

说明：  实现了mqtt client的数据交互流程，跨平台使用(The data interaction flow of mqtt client is realized and used across platforms)

说明：  利用粒子群算法进行优化调度，以经济性为目标函数，完全可以运行(The particle swarm optimization algorithm is used to optimize the scheduling, which takes the economy as the objective function and can run completely)

用于求网络中从某一节点开始形成环路到该节点结束的节点编号。对于求路径的问题会有一定的帮助(Used to find a node the network began to form a loop to the end node node numbers. To seek the path of problem would certainly help)
