numpy.polynomial.hermite.hermpow

numpy.polynomial.hermite.hermpow(c, pow, maxpower=16)[source]

Raise a Hermite series to a power.

Returns the Hermite series c raised to the power pow. The argument c is a sequence of coefficients ordered from low to high. i.e., [1,2,3] is the series P_0 + 2*P_1 + 3*P_2.

Parameters :

c : array_like

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

pow : integer

Power to which the series will be raised

maxpower : integer, optional

Maximum power allowed. This is mainly to limit growth of the series to unmanageable size. Default is 16

Returns :

coef : ndarray

Hermite series of power.

Examples

>>> from numpy.polynomial.hermite import hermpow
>>> hermpow([1, 2, 3], 2)
array([ 81.,  52.,  82.,  12.,   9.])
