SchurPolR: Schur polynomial

In jack: Jack, Zonal, Schur, and Other Symmetric Polynomials

Schur polynomial

Description

Returns the Schur polynomial.

Usage

SchurPolR(n, lambda, algorithm = "DK", basis = "canonical", exact = TRUE)

Arguments

n	number of variables, a positive integer
lambda	an integer partition, given as a vector of decreasing integers
algorithm	the algorithm used, either "DK" or "naive"
basis	the polynomial basis for algorithm = "naive", either "canonical" or "MSF" (monomial symmetric functions); for algorithm = "DK" the canonical basis is always used and this parameter is ignored
exact	logical, whether to use exact arithmetic

Value

A mvp multivariate polynomial (see mvp-package), or a qspray multivariate polynomial if exact = TRUE and algorithm = "DK", or a character string if basis = "MSF".

Examples

SchurPolR(3, lambda = c(3,1), algorithm = "naive")
SchurPolR(3, lambda = c(3,1), algorithm = "DK")
SchurPolR(3, lambda = c(3,1), algorithm = "DK", exact = FALSE)
SchurPolR(3, lambda = c(3,1), algorithm = "naive", basis = "MSF")
