Adaptive Procedure for Approximating Functions by Continuous Piecewise Polynomials.

Abstract

We consider the problem of approximating function in a general domain in one and two dimensions using piecewise polynomial interpolation. We propose an error estimator and show how to adaptively determine the interpolation degree. Numerical examples are given. (AN)
