Are We There Yet? Zero Crossing and Event Handling for Differential Equations

By Cleve Moler, MathWorks

When does the bouncing Mars Pathfinder hit the surface? When is a car’s engine speed close enough to its transmission speed for the clutch to engage? When does the price for an options contract hit the strike price? The five new ordinary differential equation solvers available in MATLAB® 5 and Simulink® 2 provide the features necessary to answer these questions.

In this article, originally published in 1997, Cleve Moler describes the advantages that the new stopping functions, g-stops, have over tf values in the ordinary differential equation solvers available in MATLAB 5 and Simulink 2.
