Variable mesh spline approximation method for solving singularly perturbed turning point problems having boundary layer(s)
A numerical method based on cubic spline with nonuniform grid is given for the singularly perturbed two-point boundary value problems having turning point. The scheme derived in this paper is second-order accurate. Numerical examples are given to support the predicted theory. (C) 2001 Elsevier Science Ltd. All rights reserved.
