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.
1-D array of Laguerre series coefficients ordered from low to high.
Power to which the series will be raised
Maximum power allowed. This is mainly to limit growth of the series to unmanageable size. Default is 16
Laguerre series of power.
Examples
>>> from numpy.polynomial.laguerre import lagpow
>>> lagpow([1, 2, 3], 2)
array([ 14., -16., 56., -72., 54.])
