In mpoly: Symbolic Computation and More with Multivariate Polynomials

Description

Compute quantities/expressions related to a multivariate polynomial.

Usage

## S3 method for class 'mpoly'
x[ndx]

LT(x, varorder = vars(x), order = "lex")

LC(x, varorder = vars(x), order = "lex")

LM(x, varorder = vars(x), order = "lex")

multideg(x, varorder = vars(x), order = "lex")

totaldeg(x)

monomials(x)

exponents(x, reduced = FALSE)

Arguments

x	an object of class mpoly
ndx	a subsetting index
varorder	the order of the variables
order	a total order used to order the terms
reduced	if TRUE, don't include zero degrees

Value

An object of class mpoly or mpolyList, depending on the context
