Sorting monomials with respect to a term ordering

polylib::sortMonomials(f) polylib::sortMonomials(f, vars) polylib::sortMonomials(f, ord) polylib::sortMonomials(f, vars, ord)
polylib::sortMonomials(f, ord) returns a list of all monomials constituting the polynomial f, sorted in descending order with respect to ord.
A monomial ordering may be: one of the identifiers LexOrder, DegreeOrder, DegInvLexOrder; or an object of type Dom::MonomOrdering or convertible to that type; or any object returning a number when called as ord(m1,m2) for two degree vectors m1 and m2. A degree vector is a list of integers, as returned by degreevec.
If no order is given, the lexikographical order is used.
If no list of variables is given, all indeterminates of f are used.
Given two degree vectors, m1 is considered to be greater than m2 if and only if ord(m1,m2) is positive.
The monomials of the polynomial below are compared using a monomial ordering from Dom::MonomOrdering .
