Laguerre matrix method with the residual error estimation for solutions of a class of delay differential equations

Abstract

In this study, a practical matrix method based on Laguerre polynomials is presented to solve the higher-order linear delay differential equations with constant coefficients and functional delays under the mixed conditions. Also, an error analysis technique based on residual function is developed and applied to some problems to demonstrate the validity and applicability of the method. In addition, an algorithm written in Matlab is given for the method. Copyright (c) 2013 John Wiley & Sons, Ltd.
