Comparison of solutions of systems of delay differential equations using Taylor collocation method, Lambert W function and variational iteration method

Abstract

In this paper, solution of systems of delay differential equations, with initial conditions, using numerical methods, including the Taylor collocation method, the Lambert W function and the variational iteration method, is considered. We have endeavored to show the most appropriate method by comparing the solutions of this system of equations with different types of methods. All numerical computations have been performed on the computer algebraic system, Matlab. (C) 2015 Sharif University of Technology. All rights reserved.
