ANALYSIS OF R¨OSSLER ATTRACTOR BY MEANS OF RESIDUAL AND JOUBERT-GREEFF METHODS
Keywords:
R¨ossler attractor , MathCad software, Joubert-Greeff method , global and local residuals.
Abstract
In this paper, A mathematical framework of checking accuracy of numerical methods from mathematical software is been developed and investigated. R¨ossler attractor is used as case study as its analytical solution is non-existence. The algorithms investigated from Mathcad software includes AdamsBDF, Adams, BDF and Runge-Kutta fixed methods. The numerical solutions of each built-in algorithms are compared to well-known Joubert-Greeff method. The estimation of global and local residuals are shown. The graphical results are plotted on an interval of 0 < t < 150.
