System requirements

All routines run on Matlab 2012b and Matlab 2007a-32. They should run on older releases, but no validation has been performed. In particular, the numerical results provided to validate the routines have been computed with Matlab 2012b and Matlab 2007a-32. Results between these 2 versions can be slightly different.
