  # Python | Numpy np.hermex () method

Using the `np.hermex() ` method, we can get a filter that has an array of ([0, 1]) values in the hermiteE series using ` np.hermex () `.

Syntax: ` np.hermex `
Return: Return filter of array ([0, 1])

Example # 1:
In this example, we can see that with ` np.hermex () ` we can get the array ([0, 1]) filter in the hermiteE row using this method.

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

Output:

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

Example # 2:

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

Exit:

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