# been proposed for the matrix exponential, many of them of pedagogic interest only or of dubious numerical stability. Some of the more computationally useful methods are surveyed in [ ] In principle, the matrix exponential could be computed in many ways and many different methods to calculate matrix exponential [ ,9].

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. The exponential of a matrix can be defined by a power series or a differential equation.

Unless the matrix A is diagonal, there really is no way of calculating the matrix exponential function unless there are repeated eigenvalues. If you get repeated eigenvalues, you will have a polynomial of the form shown above. We can use this in the following way.. How then should the matrix exponential be introduced in an elementary differential equations course, The Mathematica GuideBook for Programming, 700-1001.

Meaning that it will eventually be the zero matrix if multiplied by itself enough times. exponential of the real skew symmetric matrix A = 0 −θ θ 0 . We ﬁnd that eA = cosθ −sinθ sinθ cosθ . Thus, eA is a rotation matrix! This is a general fact.
