Description

Given the coordinate N-vector and a metric (N x N matrix), the package defines "functions" which return the inverse metric, the Christoffel connection, the Riemann, Ricci and Einstein tensors, the Ricci scalar and the tensor-squares of the Ricci and Riemann tensors. The tensors are consistent with the standard notation of Misner, Thorn & Wheeler. Entering "helpGREAT" will list the available "function" names, and entering "?Function" will produce a brief description of the requested "Function".
