cylBessel_yn

Bessel function of second kind of integer order

Returns Bessel function of order n, where n is a (possibly negative) integer.

The function is evaluated by forward recurrence on n, starting with values computed by the routines cylBessel_y0() and cylBessel_y1().

If n = 0 or 1 the routine for cylBessel_y0 or cylBessel_y1 is called directly.
