最小生成树Prim算法。Dandn文件给出了输入参数的名称及格式即在调用prim前先输入邻接矩阵D和节点个数n输入prim得到两行的矩阵T,将上下两行数字对应的节点相连即可。-Prim minimum spanning tree algorithm. The file of Dandn up and down two rows of numbers corresponding node connected to the name and format of the input parameters that prim is called before the first two rows of the matrix T n input prim input adjacency matrix D and the number of nodes.
