The original matrix is successfully reconstructed using its eigenvalues and eigenvectors, demonstrating the process of diagonalization −Original matrix: [[2 0 0] [1 3 0] [4 5 6]] Reconstructed matrix: [[2. 0.
import numpy as np from scipy.linalg import eig # Define a 3x3 matrix A = np.array([[6, 2, 1], [2, 3, 1], [1, 1, 1]]) # Compute eigenvalues and eigenvectors eigenvalues, eigenvectors = eig(A) # Print results print("Matrix A:") print(A) print("\nEigenvalues:") print(...
We already know that methodeigh()returns the as ndarray type, and we also know that the array elements or values can be accessed by its index value. So the methodeigh()has a parametersubset_by_indexthat allows us to access the eigenvalues or eigenvectors of the ndarray using its index val...

Further, the eigenvalues calculated by the scipy.linalg.eigh routine seem to be wrong, and two eigenvectors (v[:,449] and v[:,451] have NaN entries. The eigenvalues calculated using the numpy.linalg.eigh routine matches the results of the the general scipy.linalg.ei...
