numpy.polynomial.legendre.legpow — NumPy v1.13 Manual (original) (raw)
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. |
