VFGEN

VFGEN is an exceptional software tool designed to generate Vector Field Files for differential equation solvers and other computational tools. Many programs are available for solving differential equations and computing bifurcations of vector fields; however, each program possesses a unique format for specifying the vector field that defines the differential equation. That's where VFGEN comes in – it offers the ability to define your vector field once through the use of XML and export the vector field in several formats.

VFGEN uses a powerful symbolic algebra library called GiNaC to generate Jacobians and higher derivatives automatically. It offers numerous key features that make it an excellent choice for anyone looking to simplify the process of working with differential equations. For instance, you can specify your equations once and export them to multiple different file formats, including MATLAB, Scilab, AUTO, GNU Scientific Library (GSL), SciPy, PyDSTool, XPP, and many others. Additionally, Version 2.1.0 comes equipped with Octave, PyDSTool, and RADAU5 commands.

In Version 2.0.0, VFGEN was updated to also generate code for delay equations, making it even more versatile than before. This software requires a variety of different tools and libraries, including the Class Library for Numbers, GiNaC, Mini-XML, and GNU MP (optional). However, once you have everything set up, VFGEN is an incredibly powerful and reliable tool.

This latest version of VFGEN comes with several exciting new features, including improved input validation, assorted solvers and analyzers, and numerous bug fixes. Overall, VFGEN is an essential tool for anyone who works with differential equations and requires a more straightforward way to generate vector fields for different programs. If you're looking for a reliable and user-friendly Vector Field File Generator, VFGEN is undoubtedly worth considering.
