Python | Numpy np.herm2poly method (original) (raw)

Last Updated : 02 Dec, 2019

With the help of **np.herm2poly()** method, we can get the polynomial from hermite series by using np.herm2poly() method.

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

Example #1 :
In this example we can see that by using np.herm2poly() method, we are able to get the coefficients of polynomial from hermite series using this method.

import numpy as np

from numpy.polynomial.hermite import herm2poly

x = np.array([ 0.1 , 0.2 , 0.3 , 0.4 , 0.5 ])

gfg = herm2poly(x)

print (gfg)

Output :

[5.5 -4.4 -22.8 3.2 8.]

Example #2 :

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 ])

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.]
