The contents of this zip file are provided without any warranty. They are intended for evaluational purposes only.

There are four kinds of files:
-Files with .m extension: they are Matlab files which form the top level of the implementation.
-Files with .c and .h extension: they are the C MEX low level implementation. They are as platform independent as possible.
-Files with .mexw32 extension: they are precompiled versions of the MEX files for use in Matlab under 32 bit Windows.
-Files with .mexw64 extension: they are precompiled versions of the MEX files for use in Matlab under 64 bit Windows.
-Files with .mat extension: they are databases from the UCI Machine Learning Repository. 

Any suggestions and bug reports will be welcome.
