numpy.polynomial.polynomial.polypow¶
- numpy.polynomial.polynomial.polypow(c, pow, maxpower=None)[source]¶
Raise a polynomial to a power.
Returns the polynomial 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 1 + 2*x + 3*x**2.
Parameters: c : array_like
1-D array of array of series coefficients ordered from low to high degree.
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
Power series of power.
