slegendre.recurrences: Recurrence relations for shifted Legendre polynomials

In orthopolynom: Collection of Functions for Orthogonal and Orthonormal Polynomials

Recurrence relations for shifted Legendre polynomials

Description

This function returns a data frame with n + 1 rows and four named columns containing the coefficient vectors c, d, e and f of the recurrence relations for the order k shifted Legendre polynomial, P_k^* ≤ft( x \right), and for orders k = 0,\;1,\; … ,\;n.

Usage

slegendre.recurrences(n, normalized=FALSE)

Arguments

n	integer value for the highest polynomial order
normalized	boolean value which, if TRUE, returns recurrence relations for normalized polynomials

Value

A data frame with the recurrence relation parameters.
