mars.tensor.special.yn#
- mars.tensor.special.yn(n, x, **kwargs)[source]#
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 – Value of the Bessel function, \(Y_n(x)\).
- Return type
ndarray
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 and y1. If n = 0 or 1, the routine for y0 or y1 is called directly.
