How to obtain eigenvalues

WebAs for the eigenvalues, recall the basic definition of an eigenvector: v ≠ 0 is an eigenvector of M iff M v = λ v for some scalar λ. So, multiply the eigenvectors that you have by M and extract the corresponding eigenvector with a simple division. WebTo find the eigenvalues of A, solve the characteristic equation A - λI = 0 (equation (2)) for λ and all such values of λ would give the eigenvalues. To find the eigenvectors of A, …
