poly2lag
(pol)[source]¶ Convert a polynomial to a Laguerre series.
Convert an array representing the coefficients of a polynomial (relative to the “standard” basis) ordered from lowest degree to highest, to an array of the coefficients of the equivalent Laguerre series, ordered from lowest to highest degree.
Parameters: - pol : array_like
1-D array containing the polynomial coefficients
Returns: - c : ndarray
1-D array containing the coefficients of the equivalent Laguerre series.

Notes
The easy way to do conversions between polynomial basis sets is to use the convert method of a class instance.
Examples
>>> from numpy.polynomial.laguerre import poly2lag >>> poly2lag(np.arange(4)) array([ 23., -63., 58., -18.])
