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
