D.6.6.8 modSagbiAlg
Procedure from library classify_aeq.lib (see classify_aeq_lib).
- Usage:
- modSagbiAlg(I,i); I is an ideal, i an integer (optional).
- Return:
- ideal, a sagbi basis for I using modular methods.
- Purpose:
- Computes a sagbi basis for the ideal given by the generators in I using modular techniques.
If second argument is 0 then the result is not verified.
Example:
| | LIB "classify_aeq.lib";
ring R=0,t,ds;
ideal I=t8,t10+t13,t12+t15;
modSagbiAlg(I,0);
==> _[1]=t8
==> _[2]=t10+t13
==> _[3]=t12+t15
==> _[4]=t23-t29
==> _[5]=t27
modSagbiAlg(I);
==> _[1]=t8
==> _[2]=t10+t13
==> _[3]=t12+t15
==> _[4]=t23-t29
==> _[5]=t27
