# numpy.polynomial.laguerre.lagpow

polynomial.laguerre.lagpow(c, pow, maxpower=16)

  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
    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.
