`scipy.special.``pbdv_seq`(v, x)

  Parabolic cylinder functions Dv(x) and derivatives.

  Parameters: | v : float Order of the parabolic cylinder function x : float Value at which to evaluate the function and derivatives
  Returns: | dv : ndarray Values of D_vi(x), for vi=v-int(v), vi=1+v-int(v), ..., vi=v. dp : ndarray Derivatives D_vi’(x), for vi=v-int(v), vi=1+v-int(v), ..., vi=v.
