numpy.polynomial.laguerre.lagpow()

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.

Parameters:

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.

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.])
