# numpy.polynomial.hermite.hermadd

`numpy.polynomial.hermite.hermadd(c1, c2)` [source]

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. `out : ndarray` Array representing the Hermite series of their sum.

#### 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.])
```
