NAME
       j0, j1, jn, y0, y1, yn - bessel functions

SYNOPSIS
       #include <math.h>

       double j0(x)
       double x;

       double j1(x)
       double x;

       double jn(n,x)
       int n;
       double x;

       double y0(x)
       double x;

       double y1(x)
       double x;

       double yn(n,x)
       int n;
       double x;

DESCRIPTION
       These  functions  calculate  Bessel  functions  of the first and second
       kinds for real arguments and integer orders.

DIAGNOSTICS
       On a VAX, negative arguments cause y0, y1 and yn to return the reserved
       operand and set errno to EDOM.
