The purpose of this letter is to present a method for computing the transition matrix of linear time-invariant systems. Due to the important role the transition matrix plays in linear system response, several methods have been put forward for its computation. A numerical computation method, which avoids the use of the eigenvalues, for the evaluation of the transition matrix is presented here.
