We developed a toolbox (OCMat) using the MATLAB Language to analyze optimal control problems, specifically for discounted infinite time horizon models. This toolbox allows, in general, an immediate analysis of the model after its problem formulation, since the necessary files for the computation are generated (semi)-automatically. The core framework is the formulation of a boundary value problem, where the infinite time horizon is truncated to a finite horizon and the usual transversality conditions are replaced by so-called asymptotic transversality conditions. This approach is very flexible as it allows the consideration of mixed and pure state constraints as well as the consideration of multi-stage problems. But also the computation and continuation of Skiba points, junction points between boundary and interior arcs or heteroclinic connections can easily be done.
