 ### Read and write MATLAB files in Julia
 
 This library can read MATLAB `.mat` files, both in the older v4/v5/v6/v7 format, as well as the newer v7.3 format.

 ## Credits
 
 The MAT_HDF5 module, which provides read/write support for MATLAB v7.3 files, was written primarily by [Tim Holy](https://github.com/timholy/). The MAT_v5 module, which provides read support for MATLAB v5/v6/v7 files, was written primarily by [Simon Kornblith](https://github.com/simonster/). The MAT_v4 module, which provides read and write support for MATLAB v4 files, was written primarily by [Victor Saase](https://github.com/vsaase/).
