Mathematical software: Plod

The authors present Plod (plotted solutions of ordinary differential equation), mathematical software Fortran package designed by integrating large systems of equations that are unstable with respect to initial conditions (stiff). It is intended for microcomputer users unfamiliar with programming techniques. The hardware needed to run Plod is described. Plod is designed to be used in two interactive steps, and an example of each is given. Graphics capabilities and extensibility are briefly considered.<
