spherical.polynomials {orthopolynom}R Documentation

Create list of spherical polynomials

Description

This function returns a list with $n$+1 elements containing the order $k$ spherical polynomials, P_k ( x ), for orders $k$ = 0, 1, ..., $n$.

Usage

spherical.polynomials(n, normalized=FALSE)

Arguments

n integer highest polynomial order
normalized a boolean value which, if TRUE, returns a list of normalized orthogonal polynomials

Details

The function produces a data frame with the recurrence relation parameters for the orthogonal polynomials. It then uses the function orthogonal.polynomials to construct the list of polynomial objects from the recurrence relations.

Value

A list of $n$+1 polynomial objects

1 order 0 spherical polynomial
2 order 1 spherical polynomial
n+1 order $n$ Chebyshev polynomial
