numpy.polynomial.hermite.hermadd

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, c2array_like

1-D arrays of Hermite series coefficients ordered from low to high.

Returns

outndarray

Array representing the Hermite series of their sum.

hermsub, hermmulx, 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.])
