用matlab模拟光线在三棱镜中的轨迹，以及顶角与折射方向的关系(stimulated ray trace in triple prism )

说明：  k均值分类 效率高 代码简单 利用最小均方误差准则编写(k-means efficient)

里面有两个程序一个可以方便改变网络节点连接方向的程序，非常好用，另一个可以生成随机图，对研究网络的性能很有帮助(There are two programs that can easily change the direction of the program to connect network nodes, very easy to use, one can generate random maps, useful for the study of network performance)
