Python | Numpy np.poly2herm() method

With the help of np.poly2herm() method, we can get the hermite series coefficient from polynomial by using np.poly2herm() method.

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

Example #1 :
In this example we can see that by using np.poly2herm() method, we are able to get the coefficients of hermite series from polynomial using this method.

# import numpy and poly2herm
import numpy as np
from numpy.polynomial.hermite import poly2herm

x = np.array([0.1, 0.2, 0.3, 0.4, 0.5])
# using 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, 0.3, 0.4, 0.5])
# using np.poly2herm() method
gfg = poly2herm(x)

print(gfg)

Output :
