yn
(n, x) = <ufunc 'yn'>¶ Bessel function of the second kind of integer order and real argument.
Parameters: - n : array_like
Order (integer).
- z : array_like
Argument (float).
Returns: - Y : ndarray
Value of the Bessel function, \(Y_n(x)\).

yv
- For real order and real or complex argument.
Notes
Wrapper for the Cephes [1] routine
yn
.The function is evaluated by forward recurrence on n, starting with values computed by the Cephes routines
y0

is called directly.References
