GEMPACK Release 12.1 now available.. More details here.
- GEMPACK enables modellers to solve very large systems of non-linear equations.
- Once the model equations have been specified using an algebra-like notation, modellers are freed from the computing details of the solution process.
- The GEMPACK software calculates accurate solutions of the economic model.
- All features (basic and advanced) are fully documented. Detailed instructions (including many hands-on examples) help new users to get started.
- GEMPACK Windows programs help you visualize and explore code, data and results.
- GEMPACK contains powerful capabilities for solving recursive-dynamic and fully-intertemporal models.
- Prompt feedback is given when problems are reported.
- We present regular training courses. Or, try the free, introductory-level Minimal course. No additional software is needed.
- GEMPACK is effective as a teaching tool, for classroom use.
- GEMPACK is used in over 400 organisations in over 90 countries (press report).
- GEMPACK is continually improved -- latest release is GEMPACK 12.
