numpy.polynomial.legendre.legpow(c, pow, maxpower=16)
[source]
Raise a Legendre series to a power.
Returns the Legendre 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 Legendre 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 Legendre series of power. |
