BERName:
where J_{v} is the Bessel function of the first kind. The functions described here compute these functions for the case when there is a real, nonnegative input argument and order zero (i.e., v = 0). Dataplot computes these function using the KLVNA routines from "Computation of Special Functions" (see the References section below).
where <x> is a nonnegative number, variable or parameter; <yr> is a variable or a parameter (depending on what <x> is) where the computed Kelvin value is stored; and where the <SUBSET/EXCEPT/FOR qualification> is optional. This syntax computes the real component of the Kelvin function of the first kind.
where <x> is a nonnegative number, variable or parameter; <yc> is a variable or a parameter (depending on what <x> is) where the computed Kelvin value is stored; and where the <SUBSET/EXCEPT/FOR qualification> is optional. This syntax computes the complex component of the Kelvin function of the first kind.
<yr> is a variable or a parameter (depending on what <x> is) where the computed Kelvin value is stored; and where the <SUBSET/EXCEPT/FOR qualification> is optional. This syntax computes the real component of the derivative of the Kelvin function of the first kind.
