vswf.sbf: Calculation of Spherical Bessel Functions.

In wendellopes/rvswf: RVSWF: Expansion in Vector Spherical Wave Functions written in R

Description

Calculation of Spherical Bessel Functions.

Usage

vswf.sbf(lmax, xo, compare = FALSE, verbose = FALSE)

Arguments

lmax	The maximum value of l.
xo	The argument of j_l. Can be real or complex.
compare	Make the comparison with the GSL (Gnu Scientific Library).
verbose	Shows the normalizations on downward recurrence.

Details

We use Lentz method for calculating the starting value j_lmax(x)=bo+(a1/b1+)(a2/b2+)(a3/b3+)...(an/bn), and then we use downward recurrence to calculate the other values, from lmax-1 to 0.

Value

An array with the Spherical Bessel functions and its derivatives.
