Positive de64257nite matrices ar e even bet ter Symmetric matrices A symmetric matrix is one for which A T If a matrix has some special pr operty eg its a Markov matrix its eigenvalues and eigenvectors ar e likely to have special pr operties as we Joy Visualization and Graphics Research Group Department of Computer Science University of California Davis In engineering applications eigenvalue problems are among the most important problems connected with matrices In this section we give the bas De64257nition 2 Computation and Properties 3 Chains brPage 3br Generalized Eigenvectors Math 240 De64257nition Computation and Properties Chains Motivation Defective matrices cannot be diagonalized because they do not possess enough eigenvectors to Were looking at linear operators on a vector space that is linear transformations 7 from the vector space to itself When has 64257nite dimension with a speci64257ed basis then is described by a square matrix Were particularly interested in the Review of properties of vibration and buckling modes.
