mpoly: Multivariate polynomials in R.

Description

A package for symbolic computation and more with multivariate polynomials

mpoly is the most basic function used to create objects of class mpoly. However, it is not a general purpose function; for that see mp().

Usage

mpoly(list, varorder)

Arguments

list

a list from which to construct an mpoly object

varorder

(optional) a character vector setting the intrinsic variable order of the polynomial

Value

Object of class mpoly.
