Abstract In this paper, a nonclassical sinc collocation method is constructed for the numerical solution of systems second-order integro-differential equations Volterra and Fredholm types. The novelty approach based on using new weight function instead classic ones. functions used to reduce system algebraic equations. Furthermore, convergence proposed theoretically, showing that converges expon...

In this work, we have studied a numerical scheme based on Sinc collocation method to solve class of nonlinear singularly perturbed boundary value problems. The solution the problems exhibit layer both sides or one side domain due presence perturbation parameter ?. can control oscillations in computed solutions at regions naturally because distribution points is denser near boundaries. convergen...
