Unformatted text preview: Eigen Values & Eigen Vectors Let A be n x n matrix. is eigen value of A if there exists a nonzero vector n R x such that x Ax x is called an eigen vector of A associated with Eigen value / proper value / characteristic value / latent value eigen vector / proper vector / characteristic vector / latent vector . NOTE: 0 can not be an eigenvector but 0 can be an eigenvalue. A may have many different eigenvectors associated with an eigenvalue , since r , rx is also an eigenvector if x is an eigenvector of A . Ex.1 : Let n I A . Find it’s eigenvalues and corresponding eigenvectors. Sol. : Eigenvalue : 1 Eigenvector : every nonzero vector n R x Ex.2 : Let 2 6 1 3 A Find the eigenvalues of A and associated eigenvectors. Sol. : Eigenvalue : 5 , Eigenvectors associated with : , 3 r r r , In particular, 3 1 Eigenvectors associated with 5 : , 2 r r r , In particular, 2 1 Definition : Let ] [ ij n n a A . Then nn n n n n n a a a a a a a a a A I f...
