scipy.special.jnyn_zeros#

scipy.special.jnyn_zeros(n, nt)[source]#

Compute nt zeros of Bessel functions Jn(x), Jn’(x), Yn(x), and Yn’(x).

Returns 4 arrays of length nt, corresponding to the first nt zeros of Jn(x), Jn’(x), Yn(x), and Yn’(x), respectively. The zeros are returned in ascending order.

Parameters
nint

Order of the Bessel functions

ntint

Number (<=1200) of zeros to compute

Returns
Jnndarray

First nt zeros of Jn

Jnpndarray

First nt zeros of Jn’

Ynndarray

First nt zeros of Yn

Ynpndarray

First nt zeros of Yn’
