#22 How to save a Matlab 7.3 file?

[Paul Bignier]

The documentation states that matio can handle Matlab 7.3 files
http://ftp.jaist.ac.jp/pub/sourceforge/m/project/ma/matio/matio/1.5.0/matio_user_guide.pdf page 11

But matio.h only proposes two compression modes: MAT_COMPRESSION_NONE and MAT_COMPRESSION_ZLIB. This restrains Mat_VarWrite() to those two modes, whereas Matlab states that 7.3 has a new compressed format, based on HDF5.

In Scilab, save() being directly linked to Mat_VarWrite(), I currently don't see how to save a Matlab 7.3 file.

Thank you for your time,

Sorry, wrong link for the Scilab bug. Here is the right one:

v7.3 files are not a compression format, but a different file format. You can create v7.3 files by setting the appropriate version (MAT_FT_MAT73) when calling Mat_CreateVer.
