-
numpy.polynomial.laguerre.lagpow(c, pow, maxpower=16)
[source] -
Raise a Laguerre series to a power.
Returns the Laguerre series
c
raised to the powerpow
. The argumentc
is a sequence of coefficients ordered from low to high. i.e., [1,2,3] is the seriesP_0 + 2*P_1 + 3*P_2.
Parameters: -
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
Returns: -
coef : ndarray
-
Laguerre series of power.
Examples
>>> from numpy.polynomial.laguerre import lagpow >>> lagpow([1, 2, 3], 2) array([ 14., -16., 56., -72., 54.])
