NAME
j0, j1, jn, y0, y1, yn - Bessel functions
SYNOPSIS
#include <math.h>
double j0(double x);
double j1(double x);
double jn(int n, double x);
double y0(double x);
double y1(double x);
double yn(int n, double x);
DESCRIPTION
The j0() and j1() functions return Bessel functions of x
of the first kind of orders 0 and 1, respectively. The jn() function
returns the Bessel function of x of the first kind of order n.
The y0() and y1() functions return Bessel functions of x
of the second kind of orders 0 and 1, respectively. The yn() function
returns the Bessel function of x of the second kind of order n.
For the functions y0(), y1() and yn(), the value of x
must be positive. For negative values of x, these functions return
-HUGE_VAL.
CONFORMING TO
SVID 3, BSD 4.3
BUGS
There are errors of up to 2e-16 in the values returned by j0(),
j1() and jn() for values of x between -8 and 8.
