Bir grafiğin bitişiklik matrisinden çizilmesi

Question

MATLAB'de, komşu matris verilen grafikleri çizmeme yardımcı olabilecek bir komut arıyorum. Biri bana yardım edebilir mi? Daha ben, bir grafik üzerinde nokta arasındaki en kısa mesafeyi hesaplamak için setler vs sayesinde

%GPLOT Plot graph, as in "graph theory". 
% GPLOT(A,xy) plots the graph specified by A and xy. A graph, G, is 
% a set of nodes numbered from 1 to n, and a set of connections, or 
% edges, between them. 
% 
% In order to plot G, two matrices are needed. The adjacency matrix, 
% A, has a(i,j) nonzero if and only if node i is connected to node 
% j. The coordinates array, xy, is an n-by-2 matrix with the 
% position for node i in the i-th row, xy(i,:) = [x(i) y(i)]. 
% 
% GPLOT(A,xy,LineSpec) uses line type and color specified in the 
% string LineSpec. See PLOT for possibilities. 
% 
% [X,Y] = GPLOT(A,xy) returns the NaN-punctuated vectors 
% X and Y without actually generating a plot. These vectors 
% can be used to generate the plot at a later time if desired. 
% 
% See also SPY, TREEPLOT.

[i,j] = find(A); 
[ignore, p] = sort(max(i,j)); 
i = i(p); 
j = j(p); 

% Create a long, NaN-separated list of line segments, 
% rather than individual segments. 

X = [ xy(i,1) xy(j,1) repmat(NaN,size(i))]'; 
Y = [ xy(i,2) xy(j,2) repmat(NaN,size(i))]'; 
Z = [ xy(i,3) xy(j,3) repmat(NaN,size(i))]'; 
X = X(:); 
Y = Y(:); 
Z = Z(:); 

if nargout==0,
