Stability Analysis for Systems of Differential Equations
www.geometrictools.comIn setting up a physical simulation involving objects, a primary step is to establish the equations of motion for the objects. These equations are formulated as a system of second-order ordinary di erential equations that may be converted to a system of rst-order equations whose dependent variables are the positions and velocities of the objects.

The diagram is a succinct way to summarize and document the various rates. The method of compartment analysis translates the diagram into a system of linear differential equations. The method has been used to
