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 :

Python3 1=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 :

Python3 1=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(4): ans = polydomain + [i-1, i + 1] print(ans)

`

Output :

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