Abstract: | A determinant equality known in linear algebra is shown to be an effective tool for control engineers in reducing complexity of eigenvalue computation and increasing insight into system behavior. Included are its applications to matrix products and singular matrices, to the study of systems with poles at the origin, and to the problem of finding the characteristic equation of an optimal regulator problem. |
