Repeated eigenvalue.

The procedure to use the eigenvalue calculator is as follows: Step 1: Enter the 2×2 or 3×3 matrix elements in the respective input field. Step 2: Now click the button “Calculate Eigenvalues ” or “Calculate Eigenvectors” to get the result. Step 3: Finally, the eigenvalues or eigenvectors of the matrix will be displayed in the new window.Sep 17, 2022 · The eigenvalues are the roots of the characteristic polynomial det (A − λI) = 0. The set of eigenvectors associated to the eigenvalue λ forms the eigenspace Eλ = ul(A − λI). 1 ≤ dimEλj ≤ mj. If each of the eigenvalues is real and has multiplicity 1, then we can form a basis for Rn consisting of eigenvectors of A.

In the above solution, the repeated eigenvalue implies that there would have been many other orthonormal bases which could have been obtained. While we chose to take \(z=0, y=1\), we could just as easily have taken \(y=0\) or even \(y=z=1.\) Any such change would have resulted in a different orthonormal set.
