Hi, GiNaC 1.3.3 is out and available. The changes are: - Fixed bug occuring in algebraic substitutions with expressions involving indices. - Fixed bug that selected the wrong algorithm for determinants of purely numeric matrices with at least one floating point element. - Fixed bug in function H that caused an infinite recursion for arguments around +-I. - Fixed const-correctness in printing handler for GCC 4.0.2. - Made lookup in adaptivesimpson precision-aware. - Added series expansion for functions (classical) Li and S around x==0. - Added fsolve() numerical univariate real-valued function solver. - Added functions sub_matrix() and reduced_matrix(). - Small cleanups. Less warnings with latest GCC. As always, this release can be downloaded from http://www.ginac.de/Download.html Enjoy, -richy. -- Richard B. Kreckel <http://www.ginac.de/~kreckel/>
