Qingtang Jiang's Matlab Routines

This is a collection of Matlab 5 routines developed for Sobolev and Holder smoothness computations of refinable functions. The routines were developed based on the theory about the smoothness of refinable functions in the following two papers [JZ] (the scalar case) and [JJ] (the vector case), and were explained and used in [JO].
[JZ] R. Q. Jia, S. R. Zhang, Spectral properties of the transition operator associated to a multivariate refinement equation, Linear Algebra Appl. 292 (1999), 155--178.
[JJ] R. Q. Jia, Q. T. Jiang, Characterization of smoothness of multivariate refinable vectors, Manuscript, July 2000.
[JO] Q. T. Jiang, P. Oswald, On the analysis of sqrt(3)-subdivision (or .pdf),Manuscript, March 2001.
These routines are free, but WITHOUT any warranty, not yet optimized with respect to user interface, numerical stability and runtime efficiency.
