Possible to come out with a adjacency matrix?

k = 1:30;
[B,V] = bucky;

axis square
subplot(1,1,1);

    subplot(1,1,1);
    gplot(B(1:30,1:30),V(1:30,:),'b-');
    for j = 1:30,
        text(V(j,1),V(j,2),int2str(j),'FontSize',10);
    end
    axis  equal

    figure(2);
    spy(B);

since spy(B) shows the non zero elements, is it possible to generate adjacency matrix?

when i type B, i didn't get 60x60 adj matrix

[ 0 0 0 0 0 1 1 1 1 1 ...
