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.
- 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.
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.”
