  # Python | The numpy np.poly2herm () method

NumPy | Python Methods and Functions

Using the `np.poly2herm() ` method we can get the coefficient of the Hermite series from a polynomial using ` np.poly2herm () `.

Syntax: ` np.poly2herm (polynomial) `
Return: Return the coefficient of hermite series.

Example # 1:
In this example, we see that using ` np.poly2herm () ` we can get the coefficients of the Hermite series from a polynomial using this method.

 ` # numpy and poly2herm imports ` ` import ` ` numpy as np ` ` from ` ` numpy.polynomial.hermite ` ` import ` ` poly2herm `   ` x ` ` = ` ` np.array ([` ` 0.1 , 0.2 , 0.3 , 0.4 , 0.5 ]) `` # using the np.poly2herm () method gfg = poly2herm (x)   print (gfg) `

Output:

[0.625 0.4 0.45 0.05 0.03125]

Example # 2:

 ` # import numpy and poly2herm ` ` import ` ` numpy as np ` ` from ` ` numpy.polynomial.hermite ` ` import ` ` poly2herm `   ` x ` ` = ` ` np.array ([` ` - ` ` 0.5 ` `, ` ` - ` ` 0.4 ` `, - 0.3 , - 0.2 , - 0.1 , 0 , 0.1 , 0.2 < / code> , 0.3 , 0.4 , 0.5 ]) `` # using the np.poly2herm () method gfg = poly2herm (x)   print (gfg) `

Output:
