将GML文件转换为matlab中的邻接矩阵 [英] Convert GML file to adjacency matrix in matlab

问题描述

我有一个 GML 文件的有向图（政治博客）。我想在Matlab中使用这个图作为一个邻接矩阵。我如何转换它？
Thanks。

I have a GML file of a directed graph (Political blogs). I want to use this graph in Matlab as an adjacency matrix. How can I convert it? Thanks.

推荐答案

有一个示例代码 here 用于此目的：

There is a sample code here for this purpose:

%Extracting edges from gml file graph
fileName = 'dolphins.gml';
inputfile = fopen(fileName);
A=[];
l=0;
k=1;
while 1
      % Get a line from the input file
      tline = fgetl(inputfile);
      % Quit if end of file
      if ~ischar(tline)
          break
      end
      nums = regexp(tline,'\d+','match');
      if length(nums)
          if l==1
              l=0;
              A(k,2)=str2num(nums{1});  
              k=k+1;
              continue;
          end
          A(k,1)=str2num(nums{1});
          l=1;
      else
          l=0;
          continue;
      end
end

A [] ，一个 [mx 2] 矩阵，包含节点之间的链接。

A[], an [m x 2] matrix, contains the links between nodes.
