NP: A maple package for performing calculations in the Newman-Penrose formalism. (English) Zbl 0613.53033

A symbolic algebra package is presented for performing computations in the Newman-Penrose formation. We illustrate the power of the package by using it to carry out a complex calculation that arises in the integration of the Petrov type-D vacuum field equations.
