# numpy.polynomial.hermite.hermadd

`numpy.polynomial.hermite.``hermadd`(c1, c2)

  Add one Hermite series to another.

  Returns the sum of two Hermite series c1 + c2. The arguments are sequences of coefficients ordered from lowest order term to highest, i.e., [1,2,3] represents the series `P_0 + 2*P_1 + 3*P_2`.

  Parameters : | c1, c2 : array_like 1-D arrays of Hermite series coefficients ordered from low to high.
  Returns : | out : ndarray Array representing the Hermite series of their sum.

  `hermsub`, `hermmul`, `hermdiv`, `hermpow`

  Notes

  Unlike multiplication, division, etc., the sum of two Hermite series is a Hermite series (without having to “reproject” the result onto the basis set) so addition, just like that of “standard” polynomials, is simply “component-wise.”

  Examples

      >>> from numpy.polynomial.hermite import hermadd
      >>> hermadd([1, 2, 3], [1, 2, 3, 4])
      array([ 2.,  4.,  6.,  4.])
