Selecting the most repeated value

Say we have the following matrix:

    >  x=[2 3 2; 4 2 3; 4 2 3; 6 43 32];

And, we do the following, such that `a` shows how many time each number was repeated in `x`:

    > [a,b]=hist(x(:),unique(x))

    a =

         4     3     2     1     1     1

    b =

         2
         3
         4
         6
        32
        43

How can we select the value which is repeated most? Which would be in our example the value `2`.

Thanks.

out = b((max(a) == a));
