chebyshev.c.polynomials: Create list of Chebyshev polynomials

Description Usage Arguments Details Value Author(s) References See Also Examples

View source: R/chebyshev.c.polynomials.R

Description

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

Usage

1

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 chebyshev.c.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 the list of orthonormal polynomial objects.

Value

A list of n + 1 polynomial objects

1

order 0 Chebyshev polynomial

2

order 1 Chebyshev polynomial

...

n+1

order n Chebyshev polynomial
