Multivariate polynomials in R.

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().

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.

list <- list(

  c(x = 0, y = 1, coef = 2),

  c(z = 1, coef = -3, x = 2),
  c(x = 1, coef = 0, x = 3),
  c(t = 1, coef = 4, t = 2, y = 4),
  c(x = 1),
  c(x = 1),
  c(coef = 5),
  c(coef = 5),
