NC.SetOrdering
Set an (admissible) ordering.
Syntax
NC.SetOrdering(Ordering)
Description
Note that default ordering is length-lexicographic ordering ("LLEX").
@param Ordering: an STRING which indicates an (admissible) ordering. For the time being, the package has supported length-lexicographic ordering ("LLEX") and elimination ordering ("ELIM").
Example
NC.RingEnv(); Coefficient ring : Q (float type in C++) Ordering : LLEX ------------------------------- NC.SetOrdering(<quotes>ELIM</quotes>); NC.RingEnv(); Coefficient ring : Q (float type in C++) Ordering : ELIM -------------------------------
