 vector.Syntax:ord (poly_expression)
 ord (vector_expression)Type:int
Purpose:returns the (weighted) degree of
the initial term of a polynomial or a vector;
the weights are the weights used for the first block of the ring ordering.
Note:ord(0)is-1.In a global degree ordering
 ordis the same asdeg.Example:|  |   ring r=7,(x,y),wp(2,3);
  ord(0);
==> -1
  poly f=x2+y3;  // weight on y is 3
  ord(f),deg(f);
==> 9 9
  ring R=7,(x,y),ws(2,3);
  poly f=x2+y3;
  ord(f),deg(f);
==> 4 9
  vector v=[x2,y];
  ord(v),deg(v);
==> 3 4
