The Exact Methods to Compute The Matrix Exponential

2016

Abstract

in this paper we present several kinds of methods that allow us to compute the exponential matrix tA e exactly. These methods include calculating eigenvalues and Laplace transforms are well known, and are mentioned here for completeness. Other method, not well known is mentioned in the literature, that don't including the calculation of eigenvectors, and which provide general formulas applicable to any matrix.
