question: public static Matrix random ( int m , int n ) { Matrix a = new Matrix ( m , n ) ; for ( int i = 0 ; i < m ; i ++ ) for ( int j = 0 ; j < n ; j ++ ) a . values [ i ] [ j ] = Math . random ( ) ; return a ; }
target:  Creates and return a randovalues.length M-by-N matrix with values between 0 and 1
