Our routines are written entirely using the programming commands of the Matlab environment and are therefore independent of the particular platform used (Unix, Windows or Mac OS based systems). In addition to the core Matlab environment, some analysis routines require the Signal Processing Toolbox. The simulation routines and the graphical interface require the Simulink Toolbox. The random number generator of the Statistics Toolbox is also used, but could be replaced by a random number generator described in the literature.
