MATLAB: How to find maximum value of 2nd column of matrix 22×2

maximum

 I have the next matrix A I want to find maximum value of 2nd column of it,
but the matlab didn't accept the step!!!
 A = [1 32143;2 1;3 98998;4 45321;5 96856;6 32143;7 9991;8 4343;9 34454;10 9991;11 9991;12 654;13 6798];
[n m] = size(A);
min = min(min(A));
max = max(max(A));
s = 1;
for k = min:max
    t = 0;
    for i = 1:n
        for j = 1:m
            if A(i,j) == k
                t = t+1;
            end
        end
    end
    N(s,:) = [k t];
    if t == 0
        N(s,:) = N(s-1,:);
        s = s-1;
    end
    s = s+1;
end
[num index] = max(N);
thanks
