# MonomialList

MonomialList[poly]

gives the list of all monomials in the polynomial poly.

MonomialList[poly,{x1,x2,}]

gives the list of monomials with respect to the variables xi in poly.

MonomialList[poly,{x1,x2,},order]

puts the monomials in the specified order.

# Details and Options • MonomialList works whether or not poly is explicitly given in expanded form.
• MonomialList[poly] is equivalent to MonomialList[poly,Variables[poly]].
• Possible settings for order are "Lexicographic", "DegreeLexicographic", "DegreeReverseLexicographic", "NegativeLexicographic", "NegativeDegreeLexicographic", "NegativeDegreeReverseLexicographic", or an explicit weight matrix.
• Monomials are sorted on the basis of their exponent vectors with respect to the variables xi.
• "NegativeLexicographic" corresponds to applying Sort to the list of exponent vectors.
• "Lexicographic" gives the reverse of "NegativeLexicographic", and is the default for MonomialList.
• "DegreeLexicographic" sorts first with respect to total degree, then by using the ordering defined by "Lexicographic".
• "DegreeReverseLexicographic" sorts first with respect to total degree, then in the negative lexicographic order by starting from the last variable.
• "NegativeDegreeLexicographic" and "NegativeDegreeReverseLexicographic" sort from lower to higher total degree.
• An explicit weight matrix w defines an ordering given by "Lexicographic" ordering of the w.vi, where the vi are the exponent vectors.
• MonomialList[poly,vars,Modulus->m] computes the coefficients modulo m.
• MonomialList[poly,All,order] is equivalent to MonomialList[poly,Variables[poly],order].
