# Python | Numpy np.poly2herme() method

• Last Updated : 11 Dec, 2019

With the help of `np.poly2herme()` method, we can get the hermiteE series from polynomial by using `np.poly2herme()` method.

Syntax : `np.poly2herme(series)`
Return : Return the coefficients of hermiteE series.

Example #1 :
In this example we can see that by using `np.poly2herme()` method, we are able to get the coefficients of hermiteE series from polynomial using this method.

 `# import numpy and poly2herme``import` `numpy as np``from` `numpy.polynomial.hermite_e ``import` `poly2herme``  ` `x ``=` `np.array([``0.1``, ``0.2``, ``0.3``, ``0.4``])``# using np.poly2herme() method``gfg ``=` `poly2herme(x)``  ` `print``(gfg)`

Output :

[0.4 1.4 0.3 0.4]

Example #2 :

 `# import numpy and poly2herme``import` `numpy as np``from` `numpy.polynomial.hermite_e ``import` `poly2herme``  ` `x ``=` `np.array([``-``0.5``, ``-``0.4``, ``-``0.3``, ``-``0.2``, ``-``0.1``, ``0``, ``0.4``, ``0.5``])``# using np.poly2herme() method``gfg ``=` `poly2herme(x)``  ` `print``(gfg)`

Output :

[ 4.9 51.5 17.1 52.3 5.9 10.5 0.4 0.5]
