写一段构建地铁网络拓扑图的matlab运行代码

以下是一个简单的Matlab代码示例，用于构建地铁网络拓扑图：

% 创建地铁网络拓扑图的Matlab代码
% 首先，创建一个空的图形对象
graph = digraph();

% 添加地铁线路节点
stations = {'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J'};
graph = addnode(graph, stations);

% 添加地铁线路边
graph = addedge(graph, 'A', 'B', 3);
graph = addedge(graph, 'A', 'C', 4);
graph = addedge(graph, 'B', 'D', 2);
graph = addedge(graph, 'C', 'D', 1);
graph = addedge(graph, 'C', 'E', 5);
graph = addedge(graph, 'D', 'F', 2);
graph = addedge(graph, 'E', 'H', 6);
graph = addedge(graph, 'F', 'G', 3);
graph = addedge(graph, 'G', 'I', 4);
graph = addedge(graph, 'H', 'I', 3);
graph = addedge(graph, 'I', 'J', 5);

% 显示地铁网络拓扑图
plot(graph);

该代码创建了一个空的有向图形对象，并向其添加了10个节点和11条边，表示地铁线路的拓扑结构。最后，使用plot函数将这个图形对象绘制出来，展示地铁网络拓扑图。
