numpy.polynomial.chebyshev.chebpow — NumPy v1.13 Manual (original) (raw)

numpy.polynomial.chebyshev. chebpow(c, pow, maxpower=16)[source]

Raise a Chebyshev series to a power.

Returns the Chebyshev 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 T_0 + 2*T_1 + 3*T_2.

Parameters: c : array_like 1-D array of Chebyshev 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 Chebyshev series of power.
