Simplified numerical methods used for the approximations of chaotic solutions of dynamical systems

This work presents simplified numerical methods for chaotic attractors. The proposed simplification consists in a rescaling technique that uses integrating factors. Because some factors are exponentials and the numerical values can grow very fast, further simplifications are introduced in the paper. These simplified numerical methods are implemented for Rössler and Lorenz systems. Numerical simulations are achieved using Matlab/Simulink programming and development environment.
