Python | Numpy np.legdomain() method (original) (raw)

Last Updated : 31 Dec, 2019

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 :

import numpy as np

from numpy.polynomial.legendre import legdomain

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 :

import numpy as np

from numpy.polynomial.legendre import legdomain

for i in range ( 4 ):

`` ans = legdomain + [i - 1 , i + 1 ]

`` print (ans)

Output :

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