With the help of np.polydomain() method, we can get the filter having value array([-1, 1]) in polynomial series.

Syntax : np.polydomain
Return : Return filter of array([-1, 1])

Example #1 :

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

Output :

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

Example #2 :

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