An explicit time stepping scheme is used for discretization of time derivatives and nonlinear terms that appeared in the equations are linearized by a linearization technique and space derivatives are discretized by Haar wavelets. In order to test the accuracy and reliability of the proposed method L-2, L-infinity error norms and conserved quantities are used. Also obtained results are compared with previous ones obtained by finite element method, Crank-Nicolson method and radial basis function meshless methods. Error analysis of Haar wavelets is also given.eninfo:eu-repo/semantics/closedAccessHaar wavelet methodcoupled nonlinear Schrodinger-KdV equationnonlinear phenomenalinearizationnumerical solutionArticle27910.1142/S01291831165010352-s2.0-84982950694Q3WOS:000382829400007Q3
