question: private void recomputeSeperation ( double [ ] [ ] means , double [ ] [ ] cdist , LongStatistic diststat ) { final int k = means . length ; for ( int i = 1 ; i < k ; i ++ ) { DoubleVector mi = DoubleVector . wrap ( means [ i ] ) ; for ( int j = 0 ; j < i ; j ++ ) { cdist [ i ] [ j ] = cdist [ j ] [ i ] = distanceFunction . distance ( mi , DoubleVector . wrap ( means [ j ] ) ) ; } } if ( diststat != null ) { diststat . increment ( ( k * ( k - 1 ) ) > > 1 ) ; } }
target:  Recompute the separation of cluster means.
