The sss Toolbox expands the capabilities of the Control System Toolbox by allowing the definition of sparse state space (sss) objects as well as analysis function (such as bode, step, isstable etc.) tailored to exploit the sparsity of the system matrices whenever this is possible.
After installation, execute the "runme" function for initial setup, including the (optional) download of benchmark models and third party-software, such as the M-M.E.S.S. toolbox.

sss is now also available on GitHub at https://github.com/MORLab/sss
