numpy.polynomial.laguerre.poly2lag
- polynomial.laguerre. 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.])
