The current Matlab version is 2013a:
/reg/common/package/matlab/r2013a/bin/matlab
You can find which nodes in the pool have a Matlab license available by running the following command:
/reg/common/package/scripts/matlic
You can find who is using the Matlab licenses, and for how long, by running the following command:
/reg/common/package/scripts/matlic --show-users
The parallel toolbox allows you to make use of multiple cores on your local node (for example the parfor command will launch matlab workers on the multiple cores that are available).
