DynPac is a comprehensive package for solving (numerically) and plotting the solutions of sets of ordinary differential equations. The plotting routines include time plots, two- and three-dimensional phase plots, animated rotated sequences of three-dimensional phase plots, and Poincare maps for both autonomous and driven systems. The purpose of this package is to provide a tool that will be useful to both students and instructors for constructing pictures of nonlinear behavior. The package comes with 12 tutorial notebooks, the titles of which give a more specific idea of the scope of the package: Integration and Plotting (2D); Integration and Plotting (3D); Equilibrium and Stability; Local Solution Near Equilibrium Point; Comparison of Integration Methods; Periodic Solutions of Autonomous Systems; Periodic Solutions of Driven Systems; Orbit Trapping and Index Theory; Phase Portraits; Bifurcation Sequences; Liapunov Functions; The Lorenz Equations.
