base_preplace(S,Rule)
It rewrites {S} by using the rule {Rule}. psubst is used instead of subst.
The replacement is not performed for function arguments.
example: base_preplace(exp(x)+x^2,[[x,a+1],[exp(x),b]]);
example_description: x is replaced by a+1 and exp(x) is replaced by b in
exp(x)+x^2.

base_sum, base_product, base_makelist accept a list as an argument. base_sum(Obj,K,B,T) base_sum returns the sum of Obj where K runs in [B,T]. Options are qt=1 (keep quote data), step (step size). When B is a list, K runs in B and T is ignored. <-- new. example: base_sum(k^2,k,1,10); example: base_sum(quote(x^2),x,1,10 | qt=1, step=0.5); example: base_sum(quote(x^2),x,[a,b,c],0 | qt=1); poly_ord_w is defined.

poly_elimination_ideal calls
noro_poly_elimination_ideal as the default.
poly_elimination_ideal(I,VV|grobner_basis,v,homo,grace,strategy)
It computes the intersection of the ideal {I} and the subring K[{VV}].
description:
If grobner_basis is "yes", I is assumed to be a Grobner basis.
The optional variable v is a list of variables which defines the ring
of polynomials.
example: poly_elimination_ideal([x^2+y^2-4,x*y-1],[x]);
example: A = poly_grobner_basis([x^2+y^2-4,x*y-1]|order=2,v=[y,x]);
poly_elimination_ideal(A,[x]|grobner_basis="yes");
When strategy=1(default),
nd_gr is used when trace=0(defauult),
nd_gr_trace is used when trace=1.
