All questions about using Cadabra can be posted on the Cadabra Q&A forum. The forum accepts LaTeX formulas and is fully searchable. If you feel your question is not ready for public consumption, please email me at firstname.lastname@example.org.
This reference guide is the place to go for a detailed specification of how Cadabra works. If you prefer to learn by example, you are better off with the tutorials. This guide is a translation of the one for 1.x, and still work-in-progress.
- The input format
- Mathematical properties
- Derivatives and implicit dependence on coordinates
- Symbol ordering and commutation properties
- Anti-commuting objects and derivatives
- Manipulating expressions
- Writing your own packages
- Programming in Cadabra
- Startup and program options, environment variables
