## NC.SetOrdering

Sets an (admissible) ordering.

### Syntax

NC.SetOrdering(Ordering:STRING)

### Description

Note that default ordering is length-lexicographic ordering ("LLEX").

@param

*Ordering*: a string which indicates an (admissible) ordering. For the time being, the package supports length-lexicographic ordering ("LLEX") and elimination ordering ("ELIM").

#### Example

NC.RingEnv(); Coefficient ring : Q Ordering : LLEX ------------------------------- NC.SetOrdering(<quotes>ELIM</quotes>); NC.RingEnv(); Coefficient ring : Q Ordering : ELIM -------------------------------
