Gibbs phenomenon removal

Matlab - 2009

The Matlab Postprocessing Toolkit (MPT) is a collection of Matlab functions that implement modern edge detection and postprocessing algorithms that remove the Gibbs phenomenon form Fourier and Chebyshev approximations of piecewise continuous functions in one and two space dimensions. The software is intended for use in applications, algorithm benchmarking, and educational purposes. The availability of the MPT should foster the idea of reproducible research in the area.

The MPT includes a graphical user interface (GUI) which allows access to the postprocessing functions and to the example benchmark problems. The development of the MPT is partially supported by NSF grant DMS-0609747.
