- numpy.polynomial.laguerre.lagpow(c, pow, maxpower=16)[source]¶
Raise a Laguerre series to a power.
Returns the Laguerre 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 P_0 + 2*P_1 + 3*P_2.
c : array_like
1-D array of Laguerre 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
coef : ndarray
Laguerre series of power.
