question: public double min ( ) { if ( isSparse ( ) && nnz ( ) < length ( ) ) { double min = 0.0 ; for ( IndexValue iv : this ) min = Math . min ( min , iv . getValue ( ) ) ; return min ; } else { double min = get ( 0 ) ; for ( int i = 1 ; i < length ( ) ; i ++ ) min = Math . min ( min , get ( i ) ) ; return min ; } }
target:  Returns the minimum value stored in this vector
