Differential Quadrature Method for the General Singular Perturbation Problems

This paper extends the application of Differential Quadrature Method (DQM) for finding the numerical solution of general singularly perturbed two point boundary value problems with a boundary layer at right end point or both end point or at an internal point. The Differential Quadrature Method is an efficient descritization technique in solving initial and /or boundary value problems accurately using a considerably small number of grid points. To demonstrate the applicability of the method, we have solved model examples with right end boundary layer, internal layer and two boundary layers and presented the computational results. It is observed that the computed result approximates the exact solution with high accuracy and efficiency.
