Mat File Versions

Its main advantage over previous versions of mat files is that it allows storing data larger than 2gb on 64 bit systems.

Mat file versions.

Unfortunately v7 3 appears to have some form of compression algorithm embedded saving and loading these v7 3 mat files istaking significant time. Currently only the uncompressed mat version 5 file format 6 is supported that is compressed mat files cannot be written only read. The only exception to this is when you create new mat files using the matfile function. But this is no longer supported.

Hdf5 based mat file support matlab 7 4 r2007a 17 1 5 0 07 2007 march 1 2007 new bsxfun function to apply element by element binary operation with singleton expansion enabled. By default all save operations create version 7 mat files. The only exception to this is when you create new mat files using the matfile function. One distinction is by level level 4 and level 5 files have completely different technical structures.

Apparently there was a nocompression flag that worked in previous versions of save. Starting with mat file version 4 there are several subsequent versions of mat files that support an increasing set of features. Matlab 7 5 r2007b 18 1 6 0 september 1 2007 last release for windows 2000 and powerpc mac. A file with the mat file extension is most likely a microsoft access table shortcut file that s used to quickly open a table without having to first open the ms access program.

Moreover the maximum variable size supported by the mat version 5 file format is 2 31 bytes 6. The mathworks matlab program uses mat files too but as a container for holding data like functions and variables. Starting with mat file version 4 there are several subsequent versions of mat files that support an increasing set of features. Matlab releases r2006b and later all support all mat file versions.

While continuing to use the same general structure new format versions have been introduced to support new capabilities. License server support for windows vista. New internal format for p code. Matlab releases r2006b and later all support all mat file versions.

For example data compression and unicode support.
