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.
Examples
>>> from numpy.polynomial import polynomial as P >>> P.polypow([1,2,3], 2) array([ 1., 4., 10., 12., 9.])
