A collocation method is developed for the approximate solutionof two-point boundary-value problems with mixed boundary conditions.The method is based on replacing the exact solution by a linearcombination of Sinc functions. No integrals need to be evaluatedapproximately when setting up the resulting system of linearequations. The error of the method converges to zero like O(exp(-cN2)),as N, where N is the number of collocation points used, andwhere c is a positive constant independent of N. It is claimedthat the method is superior to the Sinc-Galerkin method dueto its simple implementation and possible extensions to moregeneral boundary-value problems. 相似文献
