- orthax.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.
