传染病传播的SIR模型，很全，可直接应用仿真模拟-SIR model the spread of infectious diseases, it is full, the simulation can be applied directly

传统的算法是基于邻接矩阵对网络指标进行计算，而大型网络通过稀疏矩阵保存。本研究编写了可以计算稀疏矩阵的经典传染病SIS模型的程序。-The traditional method is based on network indicators adjacency matrix computing, and large networks through sparse matrix saved. The study prepared by the epidemic SIS model can calcu
