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’
