numpy.polynomial.laguerre.lag2poly(c)
[source]
Convert a Laguerre series to a polynomial.
Convert an array representing the coefficients of a Laguerre series, ordered from lowest degree to highest, to an array of the coefficients of the equivalent polynomial (relative to the “standard” basis) ordered from lowest to highest degree.
Parameters: |
c : array_like 1-D array containing the Laguerre series coefficients, ordered from lowest order term to highest. |
---|---|
Returns: |
pol : ndarray 1-D array containing the coefficients of the equivalent polynomial (relative to the “standard” basis) ordered from lowest order term to highest. |

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