Abstract:
Linear and quadratic spline interpolation methods for a one-variable function with a boundary-layer component are examined. It is shown that the interpolation method for such a function leads to considerable errors when applied on a uniform mesh. The error of linear and quadratic spline interpolations on meshes that are refined in the boundary layer is estimated. Numerical results are presented.
Key words:
refined-mesh interpolation methods, function with a boundary-layer component, spline interpolation of functions of one variable.
