The Spectral Processing Suit is for the purpose of increasing the accuracy of discrete Chebyshev approximations of discontinuous functions by reducing or eliminating the Gibbs-Wilbraham phenomenon. The suite may be used to implement a postprocessing method for the Chebyshev Collocation (Pseudospectral) or Chebyshev Spectral Viscosity methods for solving Partial Differential Equations.

The suite implements spectral filtering, edge detection, and Gegenbauer Reconstruction postprocessing algorithms.
