D.4.23.1 sagbiSPoly

Procedure from library sagbi.lib (see sagbi_lib).

Usage:
sagbiSPoly(A[, returnRing, meth]); A is an ideal, returnRing and meth are integers.

Return:
ideal or ring

Assume:
basering is not a qring

Purpose:
Returns SAGBI S-polynomials of the leading terms of a given ideal A if returnRing=0.
Otherwise returns a new ring containing the ideals algebraicRelations
and spolynomials, where these objects are explained by their name.
See the example on how to access these objects. @format The other optional argument meth determines which method is used for computing the algebraic relations.
- If meth=0 (default), the procedure std is used.
- If meth=1, the procedure slimgb is used.
- If meth=2, the prodecure uses toric_ideal.
