This directory contains external tools that may be needed. mpt: Multi Parametric Toolbox is a Matlab package that's used by the MIT RSA code. To install it on your system (Matlab installation required, obviously), you can either: Start Matlab, and at the prompt type addpath(genpath('PATH-TO-MPT')); then mpt_init to initialize the toolbox. In my case, 'PATH-TO-MPT' is '/META/src/tools/mpt/'. The trailing / alleges to be important. You can also use the Matlab GUI: File/Set Path then select Add with Subfolders. This will, tragically, dump all the .svn directories into the Matlab path as well. Harmless except for the slowdown; if you care, you can either manually remove 'em all before you save (or after, I guess). In either case, be aware that the file pathdef.m needs to go into your Matlab installation directory, which you most likely don't have write access to. Either do this as root/admin, or save it elsewhere (matlab will give you the option), then move it in manually. If you're really bothered by the Subversion files, you can also export src/tools/mpt from the repository, and add that to your Matlab path, rather than the stuff that's directly in your working copy. vs4e: Visual Swing for Eclipse An Eclipse plugin, and some runtime libraries, used to define Swing dialogs etc. This is used in the SysML plugin. You'll want to install it as an Eclipse plugin in order to design new UI elements, but otherwise the appropriate jars just need to be found to build and run the generated code.
