### There have been interested users who needed to embed the computation of the matrix exponential in their applications written in other languages such as C/C++, Java, Mathematica. Some of these users have ported Expokit directly to their native programming language of interest, while other users have preserved the original package in Fortran, and cross-linked across language boundaries.

May 25, 2008 Even though I have a Mathematica® command which computes matrix exponentials for me, it's nice to have some idea how I could check a Jun 16, 2020 exponential function for both diagonalizable and defective matrices.

Notes on the matrix exponential Erik Wahlén erik.wahlen@math.lu.se ebruaryF 14, 2012 1 Introduction The purpose of these notes is to describe how one can compute the matrix exponential eA when A is not diagonalisable. This is done in escThl by transforming A into Jordan normal form. As we will see here, it is not necessary to go this far. Use the matrix exponential to solve The characteristic polynomial is .

Here the result is easily derived from direct calculation of the series definition of the matrix exponential: d dtexp(tA) = d dt[I + tA + 1 2t2A2 + 1 3!t3A3 + ⋯] = A + tA2 + 1 … Abstract: The matrix exponential is a very important subclass of matrix functions. In this paper, we discuss some of the more common matrix exponential and some methods for computing it. In principle, the matrix exponential could be calculated in different … Instead, we can equivalently de ne matrix exponentials by starting with the Taylor series of ex: ex= 1 + x+ x2 2! + x3 3!
