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.]
