The LI Common Utilities toolbox provides basic addons that are used by other LI toolboxes and might also be useful for developers with their own projects. It might be purchased standalone but also comes with any other LI toolbox.
The utilities contain functions for m-script only, but some of them are implemented as mex-files (Matlab Executables) and some are used to handle Simulink® models. They are all compatible to at least Release R2010b and later. For more details see the user's guide chapters on different categories.
