DFIELD is an interactive tool for studying single first order differential equations.  DFIELD graphs a direction field for a given differential equation.  When the mouse button is pressed in the direction field, that point is used as an initial condition, and the resulting solution is plotted.  Options include selecting between a variety of numerical solvers and parameters of those solvers.

This software is designed as a companion for 'Ordinary Differential Equations using MATLAB' by David Arnold & John C. Polking.  Second edition published by Prentice Hall, 1999. ISBN: 0-13-011381-6.
