scipy.special.jnyn_zeros

scipy.special.jnyn_zeros(n, nt)

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.

Parameters:

n : int

Order of the Bessel functions

nt : int

Number (<=1200) of zeros to compute

See jn_zeros, jnp_zeros, yn_zeros, ynp_zeros to get separate arrays.
