numpy.polynomial.hermite_e.hermeadd — NumPy v1.13 Manual (original) (raw)
numpy.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, 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. |
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.])
