Abstract
In this paper, we solve modified Burgers equation numerically. Time discretization for modified Burgers equation is made by using finite difference approach along with a linearization technique. For space discretization, we propose two meshless approachs. One of them is based on delta-shaped basis functions-pseudo spectral method and the other is based on barycentric rational interpolation method. To see performance of the proposed methods, two test problems are investigated and obtained results are compared with other studies available in literature such as finite element, wavelet and some collocation methods. Accurate results are obtained using fewer collocation points. Further, von Neumann method has been used to discuss the stability of the methods. The comparisons show the applicability of suggested two methods.
