Selected Mathematica packages developed by Steven Wilkinson

ImplicitPlot3D.m

A package for plotting implicit equations in three variables, e.g. F(x,y,z) = 0.

ODE.m

A package for numerically solving and plotting the solutions to ordinary differential equations and systems of ordinary differential equations using fixed stepped methods The package was developed for pedagogical purposes. The syntax is the same as for Mathematica's NDSolve command except that a step size must be specified. Also, one of three numerical methods can be expressed in an option: Euler's method, modified Euler's method, and the Runga-Kutta method.

Fields.m

A package for plotting vector fields and slope fields.

ParametrizeCurve.m

A package for numerically parametrizing implicitly defined curves. (1997) The Mathematica notebook AboutParametrizeCurve.nb describes the package and gives several examples of its use.
