`scipy.special.``jnjnp_zeros`(nt)

  Compute zeros of integer-order 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.
