Consider a system with the repeated eigenvalue λ1 = λ2 and corresponding eigenvector v1. (Assume that there is not a second linearly independent eigenvector corresponding to λ1 = λ2.) With the eigenvalue λ1 and corresponding eigenvector v1, we obtain the solution to the system X1=v...
Solution. For a given matrix A, the eigenvalue problem is defined as Ax = λx, where λ is an eigenvalue and x is the corresponding eigenvector (refer to Section B.6 in Appendix B for more details). To determine the eigenvalues, we set the so-called characteristic determinant to zero...

By definition, ωl and its corresponding eigenvector vl should also satisfy the polynomial eigenvalue problem without linearization in Sect. 4.2, A(ωl )vl = 0, (115) where ⎛⎞ A1,1(ω) A1,2(ω) . . . A1,n(ω) A(ω) = ⎜⎜⎜⎝ A2,1(ω) ... A2,2(ω) ... ...
Notice that in the case of complex conjugate eigenvalues, we are able to obtain two linearly independent solutions from knowing one of the eigenvalues and an eigenvector that corresponds to it. Observe that our chosen eigenvectors are scalar multiples of the eigenvectors found with Mathematica. Examp...
