With the help of np.lagdomain() method, we can get the filter having value array([0, 1]) in laguerre series.

Syntax : np.lagdomain
Return : Return filter of array([0, 1])

Example #1 :

# Python program explaining 
# numpy.lagdomain() method  
  
# import numpy and lagdomain 
import numpy as np 
from numpy.polynomial.laguerre import lagdomain 
  
# using np.lagdomain() method 
for i in range(5): 
    ans = lagdomain + [i, i + 1] 
    print(ans) 

Output :

[-1 2] [0 3] [1 4] [2 5] [3 6]

Example #2 :

# Python program explaining 
# numpy.lagdomain() method  
  
# import numpy and lagdomain 
import numpy as np 
from numpy.polynomial.laguerre import lagdomain 
  
# using np.lagdomain() method 
for i in range(4): 
    ans = lagdomain + [i-1, i + 1] 
    print(ans)
