A computer algebra package for post-Newtonian calculations

Description

The PROCRUSTES package represents a collection of routines for the general purpose computer algebra system Maple. The routines were developed to assist you in performing calculations within the post-Newtonian approximation of General Relativity. This package is still under development and new versions will be accessible through this page as soon as they become available.

Version 1.0 of the package can also be accessed through the CPC program library.

The use of PROCRUSTES is free of any charge, users who make use of the package are asked to cite the corresponding paper D. Puetzfeld, Comp. Phys. Comm. 175 (2006) 497-508 in their works.

Installation

The package installation of the package is very easy. Create a directory of your choice and unpack the archive into that directory. Note that you need a working Maple installation to use the package. The package was tested with Maple 8 / 9.5 / 10 under different operating systems.

Please refer to the article for more information on the single files and for a general introduction to the package.

After unpacking the following files should be present:

procrustes_v1_0.mws A worksheet containing the source for all routines in the package.
procrustes_demo.mws A demo worksheet, containing several examples. Excerpts from this file are discussed in the article. Open and execute this worksheet in order to perform a complete automated test run of the package.
procrustes1_0 (subdirectory) Contains the actual routines of the package (96 files with suffix ".procrustes").
testrun_procrustes1_0 (subdirectory) Contains comparison data for the automated test run, which is performed upon execution of the demo worksheet (256 files with the suffix ".full.mpi").
