J0(3M) Mathematical Library Functions J0(3M)

NAME

j0, j0f, j0l, j1, j1f, j1l, jn, jnf, jnl - Bessel functions of the
first kind

SYNOPSIS

c99 [ flag... ] file... -lm [ library... ]
#include <math.h>

double j0(double x);


float j0f(float x);


long double j0l(long double x);


double j1(double x);


float j1f(float x);


long double j1l(long double x);


double jn(int n, double x);


float jnf(int n, float x);


long double jnl(int n, long double x);

DESCRIPTION

These functions compute Bessel functions of x of the first kind of
orders 0, 1 and n respectively.

RETURN VALUES

Upon successful completion, these functions return the relevant
Bessel value of x of the first kind.


If x is NaN, a NaN is returned.

ERRORS

No errors are defined.
