On Solving the Lorenz System by Differential Transformation Method

The differential transformation method (DTM) is employed to solve a nonlinear differential equation, namely the Lorenz system. Numerical results are compared to those obtained by the Runge--Kutta method to illustrate the preciseness and effectiveness of the proposed method. In particular, we examine the accuracy of the (DTM) as the Lorenz system changes from a
non-chaotic system to a chaotic one. It is shown that the (DTM) is robust, accurate and easy to apply.
