Kürkçu, OKAslan, ESezer, M2024-07-182024-07-180096-30031873-5649http://akademikarsiv.cbu.edu.tr:4000/handle/123456789/2474In this paper, a matrix method based on the Dickson polynomials and collocation points is introduced for the numerical solution of linear integro-differential-difference equations with variable coefficients under the mixed conditions. In addition, in order to improve the numerical solution, an error analysis technique relating to residual functions is performed. Some linear and nonlinear numerical examples are given to illustrate the accuracy and applicability of the method. Eventually, the obtained results are discussed according to the parameter -a of Dickson polynomials and the residual error estimation. (C) 2015 Elsevier Inc.
