Clang++ warns that instantiations of this inline template function ex_to<T>(const ex &) are "expression with side effects [that] will be evaluated despite being used as an operand to 'typeid'". Let's declare this ex_to<T>() as a pure function (i.e. having no side effects) for compilers which support __attribute__((__pure__)). GCC seems to support this attribute since more than ten years. ----------------------------------------------------------------------- Summary of changes: ginac/compiler.h | 2 ++ ginac/ex.h | 3 ++- 2 files changed, 4 insertions(+), 1 deletion(-) hooks/post-receive -- GiNaC -- a C++ library for symbolic computations

Find length of a vector
by Jan Rheinländer 02 Nov '24

02 Nov '24

Hi, trying to find the length of a vector by taking the square root of the scalar product, I get this (in ginsh): > v = [[a,b]]; [[a,b]] > r = sqrt(v * transpose(v)); sqrt([[a,b]]*[[a],[b]]) > evalm(r); matrix::pow(): don't know how to handle exponent The reason is that the scalar product evaluates to a matrix with a single element, not to a numeric. Is that intended? Thanks, Jan Rheinländer

GiNaC 1.8.7 released
by Richard B. Kreckel 12 Aug '23

12 Aug '23

Hi, GiNaC 1.8.7 has been released. Here're the news: * Fix series expansion of polynomial(x)^n for small and large n. Previously, this could return two Order terms or an Order term even though the series was terminating at a lower order. * Fix bugs in internal parser from strings. The operator precedence of the internal parser was inconsistent and has now been harmonized with that of ginsh. * Make ginsh evaluate line-by-line in non-interactive mode. This helps programs invoking ginsh as a sub-program. * Several build fixes. Happy hacking! -richy. -- Richard B. Kreckel <https://in.terlu.de/~kreckel/>
