Eigenvectors with i

WebSo for example, choosing y=2 yeilds the vector <3,2> which is thus an eigenvector that has eigenvalue k=3. In a general form, all eigenvectors with eigenvalue 3 have the form <2t,3t> where t is any real number. It can also be shown (by solving the system (A+I)v=0) that vectors of the form are eigenvectors with eigenvalue k=-1. Example WebThe eigenvectors with eigenvalue λ,if any, are the nonzero solutions of the equation Av=λv. We can rewrite this equation as follows: …
