  # Python | The numpy np.hermpow () method

NumPy | Python Methods and Functions

Using the `np.hermpow() ` method, we can get the cardinality of the Hermite series using ` np.hermpow () `.

Syntax: ` np.hermpow (series, pow) `
Return: Return the coefficient of series after applying power.

Example # 1:
In this example, we see that with ` np.hermpow () ` we can get the coefficient of the row after including the Hermite row using this method.

 ` # numpy and hermpow imports ` ` import ` ` numpy as np ` ` from ` ` numpy.polynomial.hermite ` ` import ` ` hermpow ` ` `  ` s eries ` ` = ` ` np.array ([` ` 1 ` `, ` ` 2 ` `, ` ` 3 ` `, ` ` 4 ` `, ` ` 5 ` `]) `   ` # using np.hermpow () method ` ` gfg ` ` = ` ` hermpow (series, ` ` 2 ` `) ` ` `  ` print ` ` (gfg) `

Output:

[10449. 8308 21970 6228 8003 1004 846 40 25]

Example # 2:

` `

` # numpy and hermpow imports import numpy as np from numpy.polynomial.hermite import hermpow   series = np.array ([ 1 , 2 , 3 ])   # using the np method. hermpow () gfg = hermpow (series, 3 )   print (gfg ) `

Output:

[2257. 2358. 3837. 908. 711. 54. 27.]
