scipy.special.jnjnp_zeros

scipy.special.jnjnp_zeros(nt)[source]

Compute nt zeros of Bessel functions Jn and Jn’.

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

Parameters:

nt : int

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.
