`numpy.polynomial.laguerre:lagadd`

source: build-install/usr/lib/python3.14/site-packages/numpy/polynomial/laguerre.py:307

Signature

def lagadd(c1, c2)

Summary

Add one Laguerre series to another.

Extended Summary

Returns the sum of two Laguerre series c1 + c2. The arguments are sequences of coefficients ordered from lowest order term to highest, i.e., [1,2,3] represents the series P_0 + 2*P_1 + 3*P_2.

Parameters

c1, c2 : array_like: 1-D arrays of Laguerre series coefficients ordered from low to high.

Returns

out : ndarray: Array representing the Laguerre series of their sum.

Notes

Unlike multiplication, division, etc., the sum of two Laguerre series is a Laguerre series (without having to "reproject" the result onto the basis set) so addition, just like that of "standard" polynomials, is simply "component-wise."

Examples

from numpy.polynomial.laguerre import lagadd

✓

lagadd([1, 2, 3], [1, 2, 3, 4])

✗

array([2., 4., 6., 4.])
