Abstract

In this paper, A mathematical framework of checking accuracy of numerical methods from mathematical software is been developed and investigated. R\"{o}ssler 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 $\le$ t $\le$ 150.
