- 13:07 CoCoA-5 Feature #1644: Allow user to choose whether to print finite field elems as symm residues or non-neg residue
- The current impl in @SmallFpImpl.H@ expects there to be a boolean data mem which says how to print (@LeastNonNeg@ or...
- 12:58 CoCoA-5 Feature #1644: Allow user to choose whether to print finite field elems as symm residues or non-neg residue
- JAA thinks that allowing the user to choose should not cause any problems: it is just a matter of printing.
Mmm, w... - 12:57 CoCoA-5 Feature #1644 (In Progress): Allow user to choose whether to print finite field elems as symm residues or non-neg residue
- A student here asked how to make CoCoA-5 print elements of a finite field as the least non-neg residue class represen...

- 13:57 CoCoALib Slug #1643: rref slower than expected (maybe) [[reduced row echelon form]]
- Here is the test I made:...
- 13:54 CoCoALib Slug #1643 (New): rref slower than expected (maybe) [[reduced row echelon form]]
- I am preparing a demo for the students, and have written a naive impl of gaussian reduction to triangular form (in Co...

- 17:15 CoCoALib Design #950: factor and SmoothFactor for integers --> FactorINT, FactorINT_TrialDiv, FactorINT_PollardRho
- I have now a prototype fn for finding *one* factor using @PollardRhoSeq@.
It takes as input @N>1@ to be factorized, ...

- 20:23 CoCoALib Bug #1641: gcd does not recognize univariate input
- I have checked in my first change (so that Anna can experiment with it).
There is more to come (if/when I find time)...

- 11:18 CoCoALib Bug #1641 (In Progress): gcd does not recognize univariate input
- I have modified the code to detect univariate inputs and to handle them "cleverly". The result is noticeably faster!...

- 21:56 CoCoALib Design #1642 (In Progress): interreduce: make monic if over finite field?
- While working on a Sudoku exercise I noticed that @interreduced@ sometimes return non-monic polynomials: coeff field ...
