numpy.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. |

The easy way to do conversions between polynomial basis sets is to use the convert method of a class instance.
