I'm wondering if there are any good programs to calculate the various tensors that one needs to solve the Einstein field equations for a very general metric i.e. metric components are not specified explicitly, only their functional dependence on the coordinates
e.g.
[tex]ds^2=-n^2(\tau,y)d\tau^2 + a^2(\tau, y)\delta_{ij}dx^idx^j[/tex]
and things that look like that.
I have Maple and Mathematica, if there are any packages for those programs that deal with stuff like this.
Thanks!
