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.
