`scipy.special.``pbdn_seq`(n, z)

  Parabolic cylinder functions Dn(z) and derivatives.

  Parameters: | n : int Order of the parabolic cylinder function z : complex Value at which to evaluate the function and derivatives
  Returns: | dv : ndarray Values of D_i(z), for i=0, ..., i=n. dp : ndarray Derivatives D_i’(z), for i=0, ..., i=n.
