注意使用nx.DiGraph,不要用nx.Graph。后者会将A转化为对称矩阵,A(i,j)=A(j,i)=1 if A(i,j) or A(j,i)=1。 G = nx.from_numpy_matrix(A, create_using=nx.DiGraph) # 从邻接矩阵创建有向图 5、度中心度degree centrality 返回所有节点的度中心度。度中心度=节点度/N-1,N是图中节点数量,N...
上述代码中,假设邻接矩阵文件名为'adjacency_matrix.txt',并且每行的数字之间使用空格分隔。 构建图:使用networkx库提供的函数,根据邻接矩阵构建图。可以使用以下代码实现: 代码语言:txt 复制 G = nx.Graph(adjacency_matrix) 上述代码中,使用nx.Graph()函数创建一个无向图,将邻接矩阵作为参数传入。 完成上述步骤...
