numpy.polynomial.laguerre.lagadd()

numpy.polynomial.laguerre.lagadd(c1, c2) [source]

Add one Laguerre series to another.

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:

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.

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.])
