A new package has been installed on tug.ctan.org and should soon make its
way through the mirroring system.

Summary description: A small set of macros to draw direction fields and
solutions of ODE's with mfpic
License type: lppl
Announcement text:

The mfpic4ode is a set of macros for drawing direction fields, phase portraits and trajectories of differential equations and two dimensional autonomous systems. The Euler, Runge-Kutta and 4th order Runge-Kutta algorithms are available to solve the ODE's. The picture is translated into mfpic macros and MetaPost is used to create the final drawing. The package is intended for LaTeX, but it can be used in plainTeX as well. Online demonstration of the mfpic4ode macros is available on http://wood.mendelu.cz/math/mfpicpreviewer/ as Example 6. You can get the documentation but compiling mfpic4ode.dtx file and the files for installation by compiling mfpic4ode.ins by LaTeX.

This package is located at http://tug.ctan.org/tex-archive/macros/latex/contrib/mfpic4ode . More information is at http://tug.ctan.org/pkg/mfpic4ode (if the package is new it may take a day for that information to appear). We are supported by the TeX Users Group http://www.tug.org .

## mfpic4ode – Macros to draw direction fields and solutions of ODEs

The package is a small set of macros for drawing direction fields, phase portraits and trajectories of differential equations and two dimensional autonomous systems. The Euler, Runge-Kutta and 4th order Runge-Kutta algorithms are available to solve the ODEs. The picture is translated into mfpic macros and METAPOST is used to create the final drawing. The package is was designed for use with LaTeX, but it can be used in plain TeX as well.

Online demonstration of the mfpic4ode macros is available on the Mfpic Previewer as Example 6.
