  # Python | Numpy np.hermdomain () method

NumPy | Python Methods and Functions

Using the `np.hermdomain() ` method, we can get a filter that has an array of values ​​([- 1, 1] ) in the hermit series using ` np.hermdomain () `.

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

Example # 1:
In this example, we can see that with ` np.hermdomain () ` we can get the array ([- 1, 1]) filter in the hermit row using this method.

 ` # import numy and hermdomain ` ` import ` ` numpy as np ` ` from ` ` numpy.polynomial.hermite import hermdomain `` ``  `  ` # using the np.hermdomain () method ` ` for ` ` i ` ` in ` ` range ` ` (` ` 5 ` `): ` ` ` ` gfg ` ` = ` ` hermdomain ` ` + ` ` [i, i ` ` + ` ` 1 ` `] ` ` print ` ` (gfg) `

Output:

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

Example # 2:

 ` # import numy and hermdomain ` ` import ` ` numpy as np ` ` from ` ` numpy.polynomial.hermite ` ` import ` ` hermdomain ` ` `  ` # using the np.hermedomain () method ` ` for ` ` i ` ` in ` ` range ` ` ( ` ` 5 ` `): ` `  gfg = hermedomain + [i - 1 , i + 1 ] `` print (gfg) `

Output:

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