Simulation of systems with variable structure

The examinations of neural network, sliding mode variable structure, multi-agent systems and complex systems often face with simulation of system with variable structure. To do this work using general-purpose computing tools will be more convenient and the error control will be more stable too. Although the current general-purpose computing tools do not include direct method which can be used for the simulation of continuous systems, but it can be solved by programming method which have been provided in general purpose computing tool. Based on the interpretation feature of MATLAB, the program structure - structure of generating subroutine will be given, and the key points of programming will be described in detail through a example system whose periods of structural change are predetermined. This method also can be used for the situations that the periods of structural change can not be determined in advance.
