legpow(c, pow, maxpower=16)¶
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.
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
coef : ndarray
Legendre series of power.
