SCICOS-a dynamic system builder and simulator

Even though it is possible to simulate mixed discrete continuous (hybrid) dynamics systems in scientific environments such as Matlab and Scilab using ordinary differential equation solvers, implementing the discrete recursions and the logic for interfacing the discrete and the continuous parts usually requires a great deal of programming. These programs are often complex, difficult to debug and slow. Scicos is a Scilab package that provides an easy to use graphical editor for building complex models of hybrid systems, a compiler which converts the graphical description into Scicos executable code, and a simulator for simulating Scicos executable codes. This paper describes briefly some of Scicos´s features
