# Python | Numpy np.hermex() method

With the help of `np.hermex()` method, we can get the filter having value array([0, 1]) in hermiteE series by using `np.hermex()` method.

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

Example #1 :
In this example we can see that by using `np.hermex()` method, we are able to get the filter of an array([0, 1]) in hermiteE series by using this method.

 `# import numpy and hermex ` `import` `numpy as np ` `from` `numpy.polynomial.hermite_e ``import` `hermex ` ` `  `# using 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 :

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

Output :

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