Using Mathematica as a platform for crystallographic computing

A comprehensive Mathematica package for crystallographic computations, MaXrd, has been developed. It comprises space-group representations based on International Tables for Crystallography, Vol. A, together with scattering factors from XOP and cross sections from xraylib. Featured functionalities include calculation of structure factors, linear absorption coefficients and crystallographic transformations. The crystal data used by MaXrd are normally generated from external .cif files. The package comes with a dynamic documentation seamlessly integrated with the Mathematica system, including code, examples, details and options. From the onset, minimal Mathematica experience is required to make use of the package. It may be a helpful supplement in research and teaching where crystallography and X-ray diffraction are essential. Although Mathematica is a proprietary software, all the code of this package is open source. It may easily be extended to cover user-specific applications.
