Determine if a graph is symmetric

symmetric.m

function yes = symmetric(g)
    % Determins if an adjacency matrix
    % is symmetric or not.
    yes = 1;
    [height width] = size(g);
    if height ~= width
        yes = 0;
    end

    for i = 1:height
        for j = i+1:width
            if g(i,j) ~= g(j,i)
                yes = 0;
            end
        end
    end
