question: private void initializeMembershipMatrix ( ) { for ( int i = 0 ; i < points . size ( ) ; i ++ ) { for ( int j = 0 ; j < k ; j ++ ) { membershipMatrix [ i ] [ j ] = random . nextDouble ( ) ; } membershipMatrix [ i ] = MathArrays . normalizeArray ( membershipMatrix [ i ] , 1.0 ) ; } }
target:  Initialize the membership matrix with random values.
