numpy.polynomial.hermite_e.hermepow

numpy.polynomial.hermite_e.hermepow(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

carray_like

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

powinteger

Power to which the series will be raised

maxpowerinteger, optional

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

Returns

coefndarray

Hermite series of power.
