 # Python | Numpy np.herm2poly method

Using the `np.herm2poly() ` method, we can get a polynomial from the Hermite series using ` np.herm2poly () `.

Syntax: ` np.herm2poly (hermite series) `
Return: Return the coefficient of polynomial.

Example # 1:
In this example we see that with ` np.herm2poly () ` we can get the coefficients polynomial from the Hermite series using this method.

 ` # import numpy and herm2poly ` ` import ` ` numpy as np ` ` from ` ` numpy .polynomial.hermite ` ` import ` ` herm2poly `   ` x = np.array ([ 0.1 , 0.2 , 0.3 , 0.4 , 0.5 ]) ```` # using the np.herm2poly () method gfg = herm2poly (x)   print (gfg) ```

Output:

[5.5 – 4.4 -22.8 3.2 8.]

Example # 2:

 ` # import numpy and herm2poly `  ` import ` ` numpy as np ` ` from ` ` numpy.polynomial.hermite ` ` import ` ` herm2poly `   ` 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.herm2poly () method gfg = herm2poly (x)   print (gfg) ```

Output:

[-14629.1 11761.6 147243.6 -31585.6 -197617.6 19084.8 79571.2
-3660.8 -11443.2 204.8 512.]
