Code snippet for reading the HDF5 files from Matlab

filename = 'modulatedgm.hdf5'
finfo = h5info(filename);
for i = 1:size(finfo.Datasets,1)
   varname = finfo.Datasets(i).Name
   var     = genvarname(varname);
   dsname  = ['/' varname];
   eval( [var '= h5read(filename, dsname);' ]);
end
clear i finfo var varname dsname

Note

In order to reduce the size of the database, the feature vector elements have been changed from float32 to float16. We haven't tested this data. If you have any problem, please contact us.
