7.7.5.0. engine
Procedure from library dmodapp.lib (see dmodapp_lib).
- Usage:
- engine(I,i); I ideal/module/matrix, i an int
- Return:
- the same type as I
- Purpose:
- compute the Groebner basis of I with the algorithm, chosen via i
- Note:
- By default and if i=0, slimgb is used; otherwise std does the job.
Example:
| | LIB "dmodapp.lib";
ring r = 0,(x,y),Dp;
ideal I = y*(x3-y2),x*(x3-y2);
engine(I,0); // uses slimgb
==> _[1]=x3y-y3
==> _[2]=x4-xy2
engine(I,1); // uses std
==> _[1]=x3y-y3
==> _[2]=x4-xy2
