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 Fa x ; the functions jn ();
and jnf ();
compute the Bessel function of the first kind of the integer order Fa n for the real value Fa x .

The functions y0 (,);
y0f (,);
y1 (,);
and y1f ();
compute the linearly independent Bessel function of the second kind of the order 0 and the order 1, respectively, for the positive real value Fa x ; the functions yn ();
and ynf ();
compute the Bessel function of the second kind for the integer order Fa n for the positive real value Fa x .
