Python | Numpy np.polydomain() method

  • Last Updated : 31 Dec, 2019

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)

Output :

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