NumPy linalg.eigh( ) method returns the eigenvalues and eigenvectors of a complex Hermitian or a real symmetric matrix.. 4. Sort Eigenvalues in descending order. Sort the Eigenvalues in the descending order along with their corresponding Eigenvector. Remember each column in the Eigen vector-matrix corresponds to a principal component, so arranging them in descending order of their Eigenvalue
