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.
