Hi all,
How can I turn the adjacency matrix into a graph of cubes like this? Also, I create my adjacency matrixes in Excel, do you have any suggestion for making them in Matlab when there are too many variables?

Thanks

You just want to visualize the pattern? Call spy on your adjacency matrix. Alternately if you need color coding see scatter, pcolor, imagesc, etc.

@Steven Lord thanks, yes, I think scatter is better but how do I create those lines where squares are filled? Like should I use multiple xline and yline? becuase the matrix includes more than 100 entries.

Ran in:
A = sprand(10, 10, 0.2);
[r, c] = find(A);
scatter(c, r, 20, 's', 'filled');
grid on
set(gca, 'YDir', 'reverse')
axis([1 10 1 10])
figure
spy(A)
grid on
axis([1 10 1 10])
