Python | Numpy np.hermecompanion() method
With the help of np.hermecompanion() method, we can get the companion matrix of hermiteE series by using np.hermecompanion() method.
Syntax :
np.hermecompanion(series)
Return : Return the companion matrix.
Example #1 :
In this example we can see that by using np.hermecompanion() method, we are able to get the companion matrix from hermiteE series by using this method.
# import numpy and hermecompanion import numpy as np from numpy.polynomial.hermite_e import hermecompanion    series = np.array([6, 7, 8, 9, 10]) # using np.hermecompanion() method gfg = hermecompanion(series)    print(gfg) |
Output :
[[ 0. 1. 0. -0.24494897] [ 1. 0. 1.41421356 -0.2857738 ] [ 0. 1.41421356 0. 1.27017059] [ 0. 0. 1.73205081 -0.9 ]]
Example #2 :
# import numpy and hermecompanion import numpy as np from numpy.polynomial.hermite_e import hermecompanion    series = np.array([1, 2, 3, 4, 5]) # using np.hermecompanion() method gfg = hermecompanion(series)    print(gfg) |
Output :
[[ 0. 1. 0. -0.08164966] [ 1. 0. 1.41421356 -0.16329932] [ 0. 1.41421356 0. 1.38564065] [ 0. 0. 1.73205081 -0.8 ]]
