numpy.polynomial.laguerre.lagpow#
- 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 seriesP_0 + 2*P_1 + 3*P_2.
- Parameters:
- carray_like
1-D array of Laguerre series coefficients ordered from low to high.
- powinteger
Power to which the series will be raised
- maxpowerinteger, optional
Maximum power allowed. This is mainly to limit growth of the series to unmanageable size. Default is 16
- Returns:
- coefndarray
Laguerre series of power.
