# Python | Numpy np.herme2poly() method

With the help of `np.herme2poly()` method, we can get the polynomial from hermiteE series by using `np.herme2poly()` method.

Syntax : `np.herme2poly(series)`
Return : Return the coefficients of polynomial.

Example #1 :
In this example we can see that by using `np.herme2poly()` method, we are able to get the coefficients of polynomial from hermiteE series using this method.

 `# import numpy and herme2poly ` `import` `numpy as np ` `from` `numpy.polynomial.hermite_e ``import` `herme2poly ` `  `  `x ``=` `np.array([``0.1``, ``0.2``, ``0.3``, ``0.4``, ``0.5``]) ` `# using np.herme2poly() method ` `gfg ``=` `herme2poly(x) ` `  `  `print``(gfg) `

Output :

[1.3 -1. -2.7 0.4 0.5]

Example #2 :

 `# import numpy and herme2poly ` `import` `numpy as np ` `from` `numpy.polynomial.hermite_e ``import` `herme2poly ` `  `  `x ``=` `np.array([``-``0.5``, ``-``0.4``, ``-``0.3``, ``-``0.2``, ``-``0.1``, ``0``, ``0.1``, ``0.2``, ``0.3``, ``0.4``, ``0.5``]) ` `# using np.herme2poly() method ` `gfg ``=` `herme2poly(x) ` `  `  `print``(gfg) `

Output :

[-4.4300e+02 3.5720e+02 2.2413e+03 -4.8320e+02 -1.5136e+03 1.4700e+02
3.0670e+02 -1.4200e+01 -2.2200e+01 4.0000e-01 5.0000e-01]
