Revision on eigenvalues and eigenvectors The eigenvalues or characteristic root s of an NГ—N matrix A are the N real or complex number О» i such that the equation Ax = О» x has non-trivial solutions О» 1 , 19 Eigenvalues, Eigenvectors, Ordinary Diп¬Ђerential Equations, and Control This section introduces eigenvalues and eigenvectors of a matrix, and discusses the role of the eigenvalues in determining the behavior of solutions of systems of ordinary diп¬Ђerential equations. An application to linear control theory is described. 19.1 Linear control theory: feedback Consider the initial value

Eigenvectors are solutions of . Obtain and . Then from we need to compute . The transformation matrix . Computing requires care since we have to do matrix multiplication and complex arithmetic at the same time. If we now want to solve an initial value problem for a linear system involving the matrix , we have to compute and . This matrix product is pretty messy to compute by hand. Even using a Nonsymmetric Eigenvalue Problems 141 Ijb^7i det( ZZ ) A ij вЂ” AI of the characteristic pP Y iiolynomials of the A and therefore that the set )(A) of eigenvalues of A is the union Ub_

The system size, the bandwidth and the number of required eigenvalues and eigenvectors deter- mine which method should be used on a particular problem.

Solution Here and so the eigenvalues are . The eigenspace corresponding to is just the null space of the given matrix which is . The eigenspace corresponding to is the null space of which is . Note: Here we have two distinct eigenvalues and two linearly independent eigenvectors (as is not a multiple of ). We also see that . 2. Find the eigenvalues and the corresponding eigenspaces of the Solution Here and so the eigenvalues are . The eigenspace corresponding to is just the null space of the given matrix which is . The eigenspace corresponding to is the null space of which is . Note: Here we have two distinct eigenvalues and two linearly independent eigenvectors (as is not a multiple of ). We also see that . 2.
