B.2.8 Extra weight vector

619#619 561#561any integers (including 0), defines 620#620and

621#621
622#622

An extra weight vector does not define a monomial ordering by itself: it can only be used in combination with other orderings to insert an extra line of weights into the ordering matrix.


Example:
 
ring r = 0, (x,y,z),  (a(1,2,3),wp(4,5,2));
ring s = 0, (x,y,z),  (a(1,2,3),dp);
ring q = 0, (a,b,c,d),(lp(1),a(1,2,3),ds);
