question: public static double [ ] [ ] ndary ( int m , int n ) { double d [ ] [ ] = new double [ m ] [ n ] ; for ( int i = 0 ; i < m ; i ++ ) { for ( int j = 0 ; j < n ; j ++ ) { d [ i ] [ j ] = R . nextGaussian ( ) ; } } return d ; }
target:  Generates a two-dimensional array of normal random doubles.
