说明：  利用matlab调用cplex实现一个简单的优化例子，例子中对参数设置有详细的说明，非常适合初学者，因为上传不能小于1k，所以复制了一下。(Using MATLAB to call CPLEX to realize a simple optimization example. In the example, the parameter setting is explained in detail, which is very suitable for beginners)

QPSK仿真系统编程。调制、信道、检测。 · 误码率仿真。 (QPSK simulation system programming. Modulation, channel detection. BER simulation.)

说明：  粒子群算法 智能算法 可以用来进行无人机的航迹规划(artificial intallgence)

这段代码是关于边界链码提取的,采用MATLAB编写,但是还有一些欠缺(This code is on the boundary chain code extraction, using MATLAB to prepare, but there are still some lack of)

设计无线传感器网络的路由协议，LEACH是第一个基于多簇结构的集群路由协议，是一种分布式的协议,每一个节点通过一个概率来决定自己是否成为簇头节点,并保证每轮有相当数量的簇头节点. (Design of wireless sensor network routing protocol, LEACH is the first structure of a cluster based on multi-cluster routing protocol, the protocol is a distributed, each node to determine their own through a probability whether a cluster head node, and to ensure that each round there is considerable number of cluster head node.)
