numpy.polynomial.hermite_e.hermeadd¶

polynomial.hermite_e.hermeadd(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, c2array_like: 1-D arrays of Hermite series coefficients ordered from low to high.

Returns

outndarray: 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_e import hermeadd
>>> hermeadd([1, 2, 3], [1, 2, 3, 4])
array([2.,  4.,  6.,  4.])
