hermite.h.polynomials: Create list of Hermite polynomials

In orthopolynom: Collection of Functions for Orthogonal and Orthonormal Polynomials

Create list of Hermite polynomials

Description

This function returns a list with n + 1 elements containing the order k Hermite polynomials, H_k ≤ft( x \right), for orders k = 0,\;1,\; … ,\;n.

Usage

hermite.h.polynomials(n, normalized=FALSE)

Arguments

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

Details

The function hermite.h.recurrences produces a data frame with the recurrence relation parameters for the polynomials. If the normalized argument is FALSE, the function orthogonal.polynomials is used to construct the list of orthogonal polynomial objects. Otherwise, the function orthonormal.polynomials is used to construct list of orthonormal polynomial objects.

Value

A list of n + 1 polynomial objects

1	order 0 Hermite polynomial
2	order 1 Hermite polynomial

...

n+1	order n Hermite polynomial
