scipy.special.jnjnp_zeros¶

scipy.special.jnjnp_zeros(nt)[source]

Compute zeros of integer-order Bessel functions Jn and Jn’.

Results are arranged in order of the magnitudes of the zeros.

Parameters
ntint

Number (<=1200) of zeros to compute

Returns
zo[l-1]ndarray

Value of the lth zero of Jn(x) and Jn’(x). Of length nt.

n[l-1]ndarray

Order of the Jn(x) or Jn’(x) associated with lth zero. Of length nt.

m[l-1]ndarray

Serial number of the zeros of Jn(x) or Jn’(x) associated with lth zero. Of length nt.

t[l-1]ndarray

0 if lth zero in zo is zero of Jn(x), 1 if it is a zero of Jn’(x). Of length nt.

jn_zeros, jnp_zeros

to get separated arrays of zeros.
