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)
double x;
int n;
double y0(x)
double x;
double y1(x)
double x;
double yn(n, x)
double x;
int n;
DESCRIPTION
These functions calculate Bessel functions of the first
and second kinds for real arguments and integer orders.
SEE ALSO
exp.3m
DIAGNOSTICS
The functions
y0, y1,
and
yn
have logarithmic singularities at the origin, so they
treat zero and negative arguments the way
log
does, as described in
exp.3m
Such arguments are unexceptional for
j0, j1,
and
jn.
