Before, matrix::rank() was hardcoded to use Bareiss elimination, which for some matrices is way too slow (and I had to work around this limitation in my own code). I propose adding an argument that will allow users to select which elimination scheme to use. The argument is the same as matrix::solve() takes (so, solve_algo::*). I've tried to mimic how a similar argument was added to matrix::inverse() by keeping the current set of rank() functions and defining separate ones with the 'algo' argument, with the old ones calling the new ones with solve_algo::automatic. This is instead of using default argument values. I've also put the code that makes the automatic selection of the elimination method into a separate function so that both matrix::solve() and matrix::rank() could share it. There's a bit of similar code in matrix::determinant(), but since the self of determinant algorithms is different from the elimination algorithms, it's not clear if these two could be unified. ----------------------------------------------------------------------- Summary of changes: doc/tutorial/ginac.texi | 14 +++---- ginac/matrix.cpp | 108 ++++++++++++++++++++++++++---------------------- ginac/matrix.h | 4 ++ 3 files changed, 69 insertions(+), 57 deletions(-) hooks/post-receive -- GiNaC -- a C++ library for symbolic computations

unintended? abi change in ginac 1.7.3
by Zbigniew Jędrzejewski-Szmek 18 Feb '18

18 Feb '18

[I'm one of the maintainers of ginac in Fedora] Hi, in recent release, GiNaC::matrix::inverse() const was inlined, which changes the ABI, and there were some other backwards-incompatible changes. See the abi diff report [1], and the bug report where this was discussed [2]. Was this intentional? > ================ changes of 'libginac.so.6.0.2'=============== > 10 Removed functions: > 'method void GiNaC::make_flat_inserter::combine_indices(const GiNaC::exvector&)' {_ZN5GiNaC18make_flat_inserter15combine_indicesERKSt6vectorINS_2exESaIS2_EE} > 'method GiNaC::matrix GiNaC::matrix::inverse() const' {_ZNK5GiNaC6matrix7inverseEv} > 'function GiNaC::function GiNaC::psi<GiNaC::ex>(const GiNaC::ex&)' {_ZN5GiNaC3psiINS_2exEEENS_8functionERKT_} > 'method cln::cl_I& cln::cl_I::operator=(const cln::cl_I&)' {_ZN3cln4cl_IaSERKS0_} > 'method cln::cl_N& cln::cl_N::operator=(const cln::cl_N&)' {_ZN3cln4cl_NaSERKS0_} > 'method cln::cl_R& cln::cl_R::operator=(const cln::cl_R&)' {_ZN3cln4cl_RaSERKS0_} > 'method const cln::cl_MI cln::cl_heap_modint_ring::canonhom(const cln::cl_I&)' {_ZN3cln19cl_heap_modint_ring8canonhomERKNS_4cl_IE} > 'method bool cln::cl_heap_modint_ring::equal(const cln::cl_MI&, const cln::cl_MI&)' {_ZN3cln19cl_heap_modint_ring5equalERKNS_5cl_MIES3_} > 'method const cln::cl_MI cln::cl_heap_modint_ring::uminus(const cln::cl_MI&)' {_ZN3cln19cl_heap_modint_ring6uminusERKNS_5cl_MIE} > 'method bool cln::cl_heap_modint_ring::zerop(const cln::cl_MI&)' {_ZN3cln19cl_heap_modint_ring5zeropERKNS_5cl_MIE} This is unfortunate, because the interface change requires a rebuild of all dependent packages, but what's worse, the fact that the so version was not changed means that dependent programs might crash instead of just failing to start. Please consider either reverting the abi-breaking changes and releasing 1.7.4, or bumping the so-version of the library (to 7.0.0 most likely) and releasing too… [1] https://bugzilla.redhat.com/attachment.cgi?id=1390882 [2] https://bugzilla.redhat.com/show_bug.cgi?id=1541187 Thanks, Zbyszek
