BesselPolynomial: Bessel Polynomials

Description

Recursively compute coefficients of Bessel Polynomials.

Deprecation warning: This function is a help function for the Bessel filters in dfilter and may be removed when dfilter will be removed.

Usage

BesselPolynomial(n, reverse = FALSE)

Arguments

n

order

reverse

whether to return the coefficients of a reverse Bessel Polynomial

Value

Returns the polynom's coefficients ordered increasing with the exponent, i.e. starting with the intercept, as for polyroot.
