%description
Toolbox containing a variety of spectral clustering tools functions. Among
the tools available are the hierarchical spectral clustering algorithm,
the Shi and Malik clustering algorithm, the Perona and Freeman algorithm,
the non-normalized clustering, the Von Luxburg algorithm, the Partition
Around Medoids clustering algorithm, a multi-level clustering algorithm,
recursive clustering and the fast method for all clustering algorithm. As
well as other tools needed to run these algorithms or useful for
unsupervised spectral clustering. This toolbox aims to gather the main
tools for unsupervised spectral classification. See
<http://mawenzi.univ-littoral.fr/> for more information and documentation.
