An Example of Clifford Algebras Calculations with GiNaC

This example of Clifford algebras calculations uses GiNaC (this http URL) library, which includes a support for generic Clifford algebra starting from version~1.3.0. Both symbolic and numeric calculation are possible and can be blended with other functions of GiNaC. This calculations was made for the paper math.CV/0410399. Described features of GiNaC are already available at PyGiNaC and due to course should propagate into other software like GNU Octave, gTybalt, which use GiNaC library as their back-end
