k均值聚类程序，虽然matlab中也有自带的，但是这个速度不错。(K mean clustering program, although matlab also has its own, but this speed is good.)

复杂网络上的静态拓扑性质的分析，包括聚类系数、平均路径长度、度、度分布，用MATLAB实现(Analysis of static topology properties on complex networks, including clustering coefficient, average path length, degree, degree distribution, with MATLAB)
