Python | Numpy np.hermfromroots() method

With the help of np.hermfromroots() method, we can get the hermite series coefficient from given roots by using np.hermfromroots() method.

Syntax : np.hermfromroots(roots)
Return : Return the coefficient of hermite series.

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

# import numpy and hermfromroot
import numpy as np
from numpy.polynomial.hermite import hermfromroots

roots = np.array([0.1, 2, 0.3, 4])
# using np.hermfromroots() method
gfg = hermfromroots(roots)

print(gfg)

Output :

[6.205 -6.49 3.3575 -0.8 0.0625]

Example #2 :

# import numpy and hermfromroot
import numpy as np
from numpy.polynomial.hermite import hermfromroots

roots = np.array([1, 2, 3, 4, 1.0001])
# using np.hermfromroots() method
gfg = hermfromroots(roots)

print(gfg)

Output :

[-7.4754225e+01 7.2628250e+01 -2.9500950e+01 6.2501250e+00
-6.8750625e-01 3.1250000e-02]
