Johanvanderknijff: Merged in text from existing MAT entry (I think merged text should be copied back there after which current entry can be removed)

-The [http://www.mathworks.com/help/pdf_doc/matlab/matfile_format.pdf published specification] makes a distinction between Level 4 and Level 5 MAT-files, where Level 4 files are compatible with older MATLAB versions (up to version 4), whereas level 5 files are compatible with MATLAB versions 5 and higher. The overall layout of a Level 4 file is quite different from Level 5, and the two might even be considered separate formats. For example, Level 4 files don't have a unique 'magic' byte pattern that would allow easy identification, whereas the header of a Level 5 file includes a descriptive text field that could be used for this.
