Well if you don't care too much about a factor of two increase in computations, you can always just do S = X X T and then K ( x i, x j) = exp ( − ( S i i + S j j − 2 S i j) / s 2) where, of course, S i j is the ( i, j) th element of S. This is probably not the most numerically stable, either, though.
