Kisil). -* Symbolic integration class added (C. Dams). -* The multiple polylogarithm Li now evaluates numerically for arbitrary arguments. -* New function G added (another notation for a multiple polylogarithm). +* The Clifford classes have been generalized to allow working with Clifford + algebras generated by arbitrary symmetric tensors or matrices. Also, a lot + of new functions for Clifford algebras have been added, including + automorphisms and Moebius transformations. [V. Kisil] +* Added some basic symbolic and numeric integration facilities. [C. Dams] +* The multiple polylogarithm Li() now evaluates numerically for arbitrary + arguments. +* New functions G(a,y) and G(a,s,y) added (another notation for multiple + polylogarithms). 1.2.4 (12 October 2004) * Added ex::unitcontprim() to compute the unit, content, and primitive parts
