OK, that is also useful, thanks. In particular, I notice that there is the concept of indexed objects in GiNaC. Is this accessible from Sage? > Or pass to Maxima and use pattern matching from Maxima, which is well > documented in documantation to Maxima. I am now confused about which system is used for the symbolics in Sage? Is it GiNaC, or Maxima, or a mixture? How can I find out which system is being used for which operation? I would very much prefer not to have to learn Maxima if I can help it, since the whole point is that Sage is supposed to provide the nice, coherent interface which makes this unnecessary! I also note that after reading the documentation, I am still left without an answer to my original question, which is how to do pattern matching in Sage (or if it's even possible) for something of the form f(i) !
