如何使用MATLAB绘制邻接矩阵 [英] How to graph adjacency matrix using MATLAB

问题描述

我想创建一个显示相邻矩阵之间节点之间连接的图.

I want to create a plot showing connections between nodes from an adjacency matrix like the one below.

gplot 似乎是最好的工具.但是，为了使用它，我需要传递每个节点的坐标.问题是我不知道坐标应该在哪里，我希望该功能能够为我找到一个好的布局.

gplot seems like the best tool for this. However, in order to use it, I need to pass the coordinate of each node. The problem is that I don't know where the coordinates should be, I was hoping the function would be capable of figuring out a good layout for me.

例如，这是使用以下任意坐标的输出:

For example here's my output using the following arbitrary coordinates:

 A = [1 1 0 0 1 0;
      1 0 1 0 1 0;
      0 1 0 1 0 0;
      0 0 1 0 1 1;
      1 1 0 1 0 0;
      0 0 0 1 0 0];

 crd = [0 1;
        1 1;
        2 1;
        0 2;
        1 2;
        2 2];

 gplot (A, crd, "o-");

很难读懂，但是如果我稍微玩弄一下坐标并将其更改为以下坐标，它将变得更加可读.

Which is hard to read, but if I play around with the coordinates a bit and change them to the following it becomes much more readable.

   crd = [0.5 0;
         0 1;
         0 2;
         1 2;
         1 1;
         1.5 2.5];

我不希望得到完美优化的坐标或其他任何东西，但是我该如何告诉MATLAB使用某种

I don't expect perfectly optimized coordinates or anything, but how can I tell MATLAB to automatically figure out a set of coordinates for me that looks okay using some sort of algorithm so I can graph something that looks like the top picture.

谢谢.

推荐答案

从R2015b开始，MATLAB现在具有一套图形和网络算法.对于此示例，您可以创建无向图对象，然后对其进行绘制使用已重载的plot函数:

As of R2015b, MATLAB now has a suite of graph and network algorithms. For this example, you can create an undirected graph object and then plot it using the overloaded plot function:

% Create symmetric adjacency matrix
A = [1 1 0 0 1 0;
     1 0 1 0 1 0;
     0 1 0 1 0 0;
     0 0 1 0 1 1;
     1 1 0 1 0 0;
     0 0 0 1 0 0];
% Create undirected graph object
G = graph(A);
% Plot
plot(G);
