Hi, GiNaC 1.3.0 is out and available. The changes are: - No funny announcements anymore. - 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. [Contribution by V. Kisil] - Added some basic symbolic and numeric integration facilities. [Contribution by 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). As always, this release can be downloaded from ftp://ftpthep.physik.uni-mainz.de/pub/GiNaC/ Enjoy, Jens

Congratulations for bringing out this ever nicer piece of software. A little disadvantage is that the patch described in http://thep.physik.uni-mainz.de/pipermail/ginac-devel/2004-September/000703.... was not taken into account. Let's see what happens... chrisd@gamow:~/c++> more test.C #include <iostream> #include <ginac/ginac.h> using namespace std; using namespace GiNaC; int main() { symbol a("a"),x("x"); ex f=integral(x,0,a,x*x); cout << f.subs(a==0,subs_options::subs_no_pattern) << endl; return 0; } chrisd@gamow:~/c++> g++ -o test test.C -lginac chrisd@gamow:~/c++> ./test Segmentation fault Oops.... However, using my patch: chrisd@gamow:~/c++> ./test 0 Much better. Best wishes, Chris

This patch has been overseen somehow ... Thanks! It's applied now. Bye, Jens

Okay. thanks. Another issue is that CVS-updating does not work at the moment. chrisd@gamow:~/ginac> cvs update [...snip...] cvs server: Updating . cvs server: failed to create lock directory for `/home/cvs/GiNaC' (/home/cvs/GiNaC/#cvs.lock): No space left on device cvs server: failed to obtain dir lock in repository `/home/cvs/GiNaC' cvs [server aborted]: read lock failed - giving up Best, Chris

Should work now (our server was out of disk space for a short time). Bye, Jens
