numpy.polynomial.polynomial.polypow — NumPy v1.11 Manual (original) (raw)
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. |
