However, if you specify the (x,y) coordinates of the nodes with the XData, YData, or ZData name-value pairs, then the figure includes axes ticks. Node labels are included automatically in plots of graphs that have 100 or fewer nodes. The node labels use the node names if available; ...

2)而在有向图中,我们只需要知道是否有从顶点i到顶点j的边,因此如果顶点i有一条指向顶点j的边,那么g[i][j]就设为1,否则设为0。有向图与无向图不同,并不需要满足g[i][j]=g[j][i]。 3)在带权值的图中, g[i][j]表示的是顶点i到顶点j的边的权值。由于在边不存在的情况下,如果将 g[i][j]...
