Matlab的+圖論+重量分配

Question

我一直在試圖標記無向圖的邊緣，另外，我用這matgraph工具！我成功地製作了一個圖表，我只想給它分配權重......請幫助！

這裏是我試過，

clear all; 
close all; 
clc; 
g=graph; 
for k=1:6 

add(g,k,k+1) 
add(g,1,4) 
add(g,5,7) 
end 
ndraw(g); 
x=rand(1,1); 
y=rand(1,1) 
A =[0 x 0 x 0 0 0; 
x 0 x 0 0 0 0; 
0 x 0 x 0 0 0; 
x 0 x 0 x 0 0; 
0 0 0 y 0 x x; 
0 0 0 0 x 0 x; 
0 0 0 0 x x 0] 

Answer 1

如果我理解正確的話，你可以，你寫的代碼後添加以下代碼：

% get line info from the figure 
lineH = findobj(gca, 'type', 'line'); 
xData = cell2mat(get(lineH, 'xdata')); % get x-data 
yData = cell2mat(get(lineH, 'ydata')); % get y-data 

% if an edge is between (x1,y1)<->(x2,y2), place a label at 
% the center of the line, i.e. (x1+x2)/2 (y1+y2)/2 etc 
labelposx=mean(xData'); 
labelposy=mean(yData'); 

% generate some random weights vector 
weights=randi(21,length(labelposx),1); 

% plot the weights on top of the figure 
text(labelposx,labelposy,mat2cell(weights), 'HorizontalAlignment','center',... 
              'BackgroundColor',[.7 .9 .7]);
