Exponentially fitted spline approximation method for solving selfadjoint singular perturbation problems

Abstract

A numerical method based on cubic spline with exponential fitting factor is given for the selfadjoint singularly perturbed two-point boundary value problems. The scheme derived in this method is second-order accurate. Numerical examples are given to support the predicted theory.
