The MATLAB GPSS Toolbox represents a modified subset of the GPSS block set in MATLAB. Moreover, it supports the combination of classic GPSS commands with MATLAB expressions in a nearly unlimitted fashion and it contains extensions for modeling and simulation of hybrid systems using MATLAB's ODE solver or the SIMULINK engine.

The toolbox was originally developed from 1997 to 1999 with MATLAB 5.3.
The recent version 1.2 is adapted to Matlab 7.5.
