function

numpy.polynomial.laguerre:poly2lag

source: build-install/usr/lib/python3.14/site-packages/numpy/polynomial/laguerre.py :94

Signature

def   poly2lag ( pol )

Summary

Convert a polynomial to a Laguerre series.

Extended Summary

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

import numpy as np
from numpy.polynomial.laguerre import poly2lag
poly2lag(np.arange(4))
