numpy.polynomial.legendre.legadd(c1, c2)
[source] -
Add one Legendre series to another.
Returns the sum of two Legendre series
c1
+c2
. The arguments are sequences of coefficients ordered from lowest order term to highest, i.e., [1,2,3] represents the seriesP_0 + 2*P_1 + 3*P_2
.Parameters: c1, c2 : array_like
1-D arrays of Legendre series coefficients ordered from low to high.
Returns: out : ndarray
Array representing the Legendre series of their sum.
Notes
Unlike multiplication, division, etc., the sum of two Legendre series is a Legendre 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 import legendre as L >>> c1 = (1,2,3) >>> c2 = (3,2,1) >>> L.legadd(c1,c2) array([ 4., 4., 4.])
