Comment:
I have fixed the computation of row-reduced echelon form.
- With the current branch, meataxe in Sage is substantially improved
compared with upstream (fixes for multiplication table IO, some speed-ups
for echelon computation, Strassen-Winograd, error handling).
- Matrix arithmetic over small non-prime fields of odd order will be
vastly faster with meataxe than with the previously used matrix
implementation in Sage.
- Doctest coverage of the Cython wrapper is 100%.
- `make test` should now pass (I need to re-run "make test" after fixing
the errors, though).
Hence: Needs review!
