- 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.
1-D array of Chebyshev series coefficients ordered from low to high.
Power to which the series will be raised
- maxpowerinteger, optional
Maximum power allowed. This is mainly to limit growth of the series to unmanageable size. Default is 16
Chebyshev series of power.
