WebWhat is the definition of eigenvector? How would you find the eigenvalues and eigenvectors of an arbitrary square matrix? An eigenvector is a nonzero vector which is mapped by a linear map (think matrix) to a multiple of itself. That multiplier is called the eigenvalue belonging to that eigenvector. brian cox cloud chamberbrian cox churchillWebSo 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.
