DMAT is an old third-party MATLAB toolbox that is no longer maintained or updated for newer versions of MATLAB. It should be considered deprecated. For recent versions of MATLAB (since 2014a) it is untested and may be broken.
DMAT is short for the Diffusion Model Analysis Toolbox. It is a MATLAB™ toolbox for fitting the Ratcliff Diffusion Model to reaction time and accuracy data. The current release of DMAT is version 0.4 (11 apr 2007).

The download package is a ZIP file that you need to unpack in your MATLAB™ toolbox directory (if you are unable to, any directory will do). Note that you need to use WinZip's "Extract" button in order to preserve the internal file structure (do not "drag" the files to a specific location on your hard disk). The package contains a collection of .m, .c, .png and .html files, and other files that together make up the DMA Toolbox. It also contains a file called readme_first.txt, which contains more detailed instructions on how to add the DMA toolbox to your MATLAB™ installation.
