WebNov 30, 2024 · To do so we can multiply λ with an identity matrix I. Therefore, Now for the right hand side to be 0 either (A-λI) should be 0 or/and v should be 0. But if you remember from the definition an eigenvector is a non zero vector. So (A-λI) should always be 0 for v to be an eigenvector. WebIn order to determine the eigenvectors of a matrix, you must first determine the eigenvalues. Substitute one eigenvalue λ into the equation A x = λ x —or, equivalently, into ( A − λ I) x = 0 —and solve for x; the resulting nonzero solutons form the set of eigenvectors of A corresponding to the selectd eigenvalue.
