Codici MATLAB per il calcolo di decomposizioni smooth di funzioni a valori matrciali

This is a collection of six matlab codes for the numerical computation of as many smooth eigendecompositions of matrices which depend on one or two real parameters. We assume no responsibility for any error that may exist in the provided functions. We welcome questions, comments, recommended changes and bug reports. A short description of the codes can be find in the attached pdf file: if you use some of them, which are the fruit of a consolidated collaboration with Professor Luca Dieci of the Georgia Institute of Tehchnology and Dr. Alessandro Pugliese of the University of Bari, the authors would appreciate your acknowledging having done so in the reports, publications, theses, etc., resulting from their use.
