Description

Calculates the ratio of Cylindrical Bessel Functions.

Usage

1
lcfe.cbd(n, x, NMAX = 2000, code = "C")

Arguments

n

The order of γ_n(x).

x

The argument of γ_n(x) of type complex.

NMAX

The maximum number of iterations.

code

Choice between C or native R code.

Details

Using Lentz method is possible to calculate the ratio γ_n(x)=J_{n}(x)/J_{n+1}(x). By downward recurrence one can calculate γ_n.

Value

The value of γ_n for complex arguments.
