NumPy | Python Methods and Functions

Using the `np.herme2poly() ` method, we can get a polynomial from the hermiteE series using ` np.herme2poly () `.

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

Example # 1:
In this example we see that with ` np.herme2poly () ` we can get the coefficients of the polynomial from the hermiteE row 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 the 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 the np.herme2poly () method ` ` gfg ` ` = ` ` herme2poly (x) `   ` print ` ` (gfg) `

` `

Output:
