Class StandardBaseSeq<C extends RingElem<C>>

java.lang.Object

edu.jas.ps.StandardBaseSeq<C>

Type Parameters:

C - coefficient type

public class StandardBaseSeq<C extends RingElem<C>>
extends java.lang.Object

Standard Base sequential algorithm. Implements Standard bases and GB test. Note: Currently the term order is fixed to the order defined by the iterator over exponent vectors ExpVectorIterator.
