Overview

This module contains components which calculate different types of Kelvin functions.

Bei

 
doubleBeidoublex )
This function uses two methods of approximation. If the argument falls below the MIN limit it uses the polynomial approximation :

otherwise it calculates its asymptotic expansion :

where

Parameters

xThe value at which the function is to be evaluated.

DBei

 
doubledBeidoublex )
This function uses two methods of approximation. If the argument falls below the MIN limit it uses the polynomial resulted by differentiating the approximation polynomial of the Bei function. Otherwise it calculates its asymptotic expansion :

where

Parameters

xThe value at which the derivative is to be evaluated.
