Python | Numpy np.legdomain() method

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

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

Example #1 :

# Python program explaining
# numpy.legdomain() method

# import numpy and legdomain
import numpy as np
from numpy.polynomial.legendre import legdomain

# using np.legdomain() method
for i in range(5):
    ans = legdomain + [i, i + 1]
    print(ans)

Output :

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

Example #2 :

# Python program explaining
# numpy.legdomain() method

# import numpy and legdomain
import numpy as np
from numpy.polynomial.legendre import legdomain

# using np.legdomain() method
for i in range(4):
    ans = legdomain + [i-1, i + 1]
    print(ans)

Output :

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