The Octave HDF5 foormat was a hack before I properly understood HDF5 
attributes. No Octqve HDF5 aren't loaded correctly with matlab. The 
matlab v7.3 file format is basically an HDF5 with the header of the HDF5 
defined to be the matlab MAT-file header. It would be good to implement 
this format and then rewrite the Octave format to be similar...
