Description

Two related packages, Ricci and Tetrad, can be used to compute the basic geometrical quantities appearing in the field equations of general relativity. The first is meant for use with coordinate basis, while the second uses orthonormal frames. The difficulties associated with the very complex expressions that usually appear in such computations may be circumvented by possible extensions to Mathematica.
