Kisil <V.Kisilv@leeds.ac.uk> Date: Mon Apr 5 21:01:30 2021 +0200 [PATCH] Improve normalisation of negative exponents. If an expression contains exponents with opposite signs, then the respective symbolic substitutions need to be properly attributed to numerator/denominator slots. commit 3d7b9dad7f51c748b52e53ce2f759ae432531de1 Author: Richard Kreckel <kreckel@ginac.de> Date: Mon Apr 5 20:57:34 2021 +0200 Add exam for ex::collect(). commit 7805dc0c2358b7774ad08cd443cd945cbd940749 Author: Richard Kreckel <kreckel@ginac.de> Date: Mon Apr 5 20:46:55 2021 +0200 [PATCH] Make ex::operator[] const dispatch to basic::operator[] const. It turned out that ex::operator[] const dispatched to non-const basic::operator[] because * member variable ex::bp is non-const and * ptr<T>::operator*() returns a non-const T &. As a result, indexing failed for multiply referenced objects. Thanks to Vitaly Magerya <vmagerya@gmail.com> for reporting this. ----------------------------------------------------------------------- Summary of changes: check/.gitignore | 1 + check/CMakeLists.txt | 1 + check/Makefile.am | 4 ++ check/exam_collect.cpp | 152 +++++++++++++++++++++++++++++++++++++++++++ check/exam_normalization.cpp | 20 ++++++ check/exam_paranoia.cpp | 22 +++++++ ginac/ex.h | 4 +- ginac/normal.cpp | 10 ++- 8 files changed, 209 insertions(+), 5 deletions(-) create mode 100644 check/exam_collect.cpp hooks/post-receive -- GiNaC -- a C++ library for symbolic computations
