Python | Numpy np.lagadd() method

Last Updated : 29 Dec, 2019

np.lagadd() method is used to add one Laguerre series to another.It returns the sum of two Laguerre series c1 + c2.

Syntax : np.lagadd(c1, c2) Parameters: c1, c2 :[ array_like ] 1-D arrays of Laguerre series coefficients ordered from low to high. Return : [ndarray] Array representing the Laguerre series of their sum.

Code #1 :

Python3

# Python program explaining
# numpy.lagadd() method 
  
# importing numpy as np  
# and numpy.polynomial.laguerre module as geek 
import numpy as np 
import numpy.polynomial.laguerre as geek
  
# Laguerre series coefficients
s1 = (1, 3, 5) 
s2 = (2, 4, 6)    
  
# using np.lagadd() method 
res = geek.lagadd(s1, s2) 

# Resulting laguerre series
print (res)

Output:

[  3.   7.  11.]

Code #2 :
