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 :

# 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 :

# 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 = (10, 20, 30, 40, 50)  
s2 = (2, 4, 6, 8, 10)     
    
# using np.lagadd() method  
res = geek.lagadd(s1, s2)
