Sort a list of polynomials with respect to the ascending order of the leading Exponent vectors. The term order is taken from the ring.

Parameters:

r - polynomial ring factory.

L - polynomial list.

Returns:

sorted polynomial list from L.

sortDegree

public static <C extends RingElem<C>> java.util.List<GenPolynomial<C>> sortDegree(java.util.List<GenPolynomial<C>> L)

Sort a list of polynomials with respect to the ascending order of the degree.

Parameters:
