     double
     y1(double x);

DESCRIPTION

     The functions j0(), j0f(), j1() and j1f() compute the Bessel function of
     the first kind of the order 0 and the order 1, respectively, for the real
     value x; the functions jn() and jnf() compute the Bessel function of the
     first kind of the integer order n for the real value x.

     The functions y0(), y0f(), y1(), and y1f() compute the linearly indepen-
     dent Bessel function of the second kind of the order 0 and the order 1,
     respectively, for the positive real value x; the functions yn() and ynf()
     compute the Bessel function of the second kind for the integer order n
     for the positive real value x.
     This set of functions appeared in Version 7 AT&T UNIX.
