本程序是稀疏矩阵(三列)的SIS模型，用于上万个节点的大型网络。因为传统的算法是基于邻接矩阵，对于大型网络并不适用。-This procedure is sparse (three) of the SIS model for large-scale network of tens of thousands of nodes. Because the traditional algorithm is based on adjacency matrix, does not apply to larg

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
