Source Code:
# sort eigenvalues and associated eigenvectors
# after using numpy.linalg.eig in python
import numpy as np
A=np.array([
[0,1],
[2,3]
])
values,vectors=np.linalg.eig(A)
idx=values.argsort()[::-1]
values=values[idx]
vectors=vectors[:,idx]
print("values")
print(values)
print("vectors:")
print(vectors)
