D.4.5.4 elim1

Procedure from library elim.lib (see elim_lib).

Usage:
elim1(id,arg); id ideal/module, arg can be either an intvec v or a product p of variables (type poly)

Return:
ideal/module obtained from id by eliminating either the variables with indices appearing in v or the variables appearing in p

Method:
elim1 calls eliminate but in a ring with ordering dp (resp. ls) if the first var not to be eliminated belongs to a -p (resp. -s) ordering.

Note:
no special monomial ordering is required.
This proc uses 'execute' or calls a procedure using 'execute'.

Example:
 
See also: elim; eliminate.
