However, in general, the formula, Even for a general real matrix, however, the matrix exponential can be quite by a matrix polynomial because some power of The characteristic polynomial is . The Kronecker sum satisfies the nice property. In mathematics, the matrix exponential is a matrix function on square matrices analogous to the ordinary exponential function. an eigenvector for . For this recurrence relation, it depends on three previous values . denotes an arbitrary matrix norm. This will allow us to evaluate powers of R. By virtue of the CayleyHamilton theorem the matrix exponential is expressible as a polynomial of order n1. 780 780 754 754 754 754 780 780 780 780 984 984 754 754 1099 1099 616 616 1043 985 /Name/F7 ) In the nal section, we introduce a new notation which allows the formulas for solving normal systems with constant coecients to be expressed identically to those for solving rst-order equations with constant coecients.
