`numpy.polynomial.chebyshev:chebpow`

source: build-install/usr/lib/python3.14/site-packages/numpy/polynomial/chebyshev.py:814

Signature

def chebpow(c, pow, maxpower = 16)

Summary

Raise a Chebyshev series to a power.

Extended Summary

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.

Examples

from numpy.polynomial import chebyshev as C
C.chebpow([1, 2, 3, 4], 2)

✓

array([15.5, 22. , 16. , 14. , 12.5, 12. ,  8. ])
