info() methods for transcendental functions
by Vladimir V. Kisil 10 Sep '22

10 Sep '22

Dear Colleagues, I am proposing a small patch which provides some elementary info() methods to GiNaC predefined transcendental functions. Only easy answers are sought, which can be decided on info tests of the functions arguments. From such coarse viewpoint functions are grouped into several classes and the respective routines can be shared. Best wishes, Vladimir -- Vladimir V.

24 Mar '22

Hi, GiNaC 1.8.3 has been tagged. The News: * series_to_poly() can be used from ginsh. * Fix power::to_polynomial() for posint exponents. * Fix power::subs() in some special cases. As always, happy hacking, and a lovely UN International Day for the Right to the Truth Concerning Gross Human Rights Violations and for the Dignity of Victims! (24 March) -richy. -- Richard B.

This could lead to messed-up final results because, e.g. substituting x==1/x in 1/x evaluated to x, but then another substitution x==1/x was performed.

Hi, We've long protested against software patentability on the GiNaC web site. In my opinion it is now time to shift focus. I have removed the Anti Software Patents Demonstration and propose to replace it with this text tomorrow morning: Call for the End of War in Ukraine The pursuit of truth is a unifying element of all scientists. And science thrives best in international cooperation. Scientists and developers from many countries, including Russia and Ukraine, have contributed to GiNaC. Without these contributions, it would not be what it is today. We strongly support the call for peace [1]. We must make the Russian government understand the value and prospect of peaceful cooperation – they must end this war now and re-enable cooperation on all fields. Let's make science, not war! [1] <https://trv-science.ru/2022/02/we-are-against-war-all/> (Russian translation to follow.) I am posting this here to avoid some contributor being offended. I am also fully aware that this may be considered off-topic. If so, you're welcome to voice this here. -richy. -- Richard B. Kreckel <https://in.terlu.de/~kreckel/>
