- 12:37 CoCoALib Design #1156: Printing for RingElem
- Part of the motivation is that it seems to be tricky to resolve issue #930 about printing out TwinFloat values as pol...
- 12:30 CoCoALib Design #1156 (New): Printing for RingElem
- JAA would like to reconsider the design of printing for @RingElem@ because the current design is rather inelegant.
- 12:28 CoCoA-5 Bug #1152: Release: problems with sed
- *(A)* The simplest solution is to call @sed@ directly without using its full path:
* *@+++@* should work everywhere

- 21:10 CoCoALib Feature #1154: SmallFpImpl: new ctor arg to say do-not-check-that-arg-is-prime
- Another posibility is for a "prime source" to produce values of a new type @SmallPrime@ (which is really just a @long...
- 20:52 CoCoALib Feature #1154: SmallFpImpl: new ctor arg to say do-not-check-that-arg-is-prime

- 20:49 CoCoALib Feature #1154 (Closed): SmallFpImpl: new ctor arg to say do-not-check-that-arg-is-prime
- I propose adding a new ctor for @SmallFpImpl@ where the caller can use a flag to guarantee that the arg is prime.
... - 21:02 CoCoALib Feature #1155: Create a new "prime source" iterator
- Add a new class to CoCoALib for generating primes in succession -- for use inside CRT loops.
Currently a CRT loop ... - 20:55 CoCoALib Feature #1155 (Closed): Create a new "prime source" iterator
- In CoCoA-4 the old factorizer code had an "iterator" for generating primes in succession.
Add such an object to Co...

- 13:48 CoCoALib Feature #1115: New class: exterior algebra
- JAA has made a first impl (mostly copying code from @RingWeyl@). Many fns are still NYI.
Anna, Michele and Elisa ...

- 15:28 CoCoA-5 Feature #368: port SmithNormalForm (CoCoA-4)package to CoCoA-5
- This should be ported to CoCoALib (once it has been corrected). It would surely be faster ;-)
- 15:27 CoCoA-5 Feature #368: port SmithNormalForm (CoCoA-4)package to CoCoA-5
- More failing examples:...
- 15:23 CoCoA-5 Feature #368 (In Progress): port SmithNormalForm (CoCoA-4)package to CoCoA-5
- Anna says she has "cleaned up" the original CoCoA-4 code so that CoCoA-5 accepts it.
The code is in @MatNormalForm.c...

- 17:32 CoCoA-5 Design #1151: ConcatList or ConcatLists
- Personally I find the name @ConcatLists@ more "natural" because it concatenates many lists.
The fns @ConcatVerList... - 17:19 CoCoA-5 Design #1151 (In Progress): ConcatList or ConcatLists
- The reason why the builtin function is called ...List is that this is the naming convention for functions operating o...
- 17:12 CoCoA-5 Design #1151: ConcatList or ConcatLists
- In the current version (5.2.2) the fn *@ConcatList@* is built-in, while *@ConcatLists@* is defined in @list.cpkg5@ an...
- 17:06 CoCoA-5 Design #1151 (Closed): ConcatList or ConcatLists
- CoCoA-5 has both *@ConcatList@* and *@ConcatLists@*. They are identical.
We should keep just one.

- 18:30 CoCoALib Feature #1150 (New): New fn: transform ideal with ring hom
- Do we want a new fun for transforming an ideal with a ringhom?
@TransformIdeal(const ideal& I, const RingHom& phi)@

- If I visit the CoCoA web site using Firefox in "private mode" then the page never finishes loading because the rectan...
19 Jan 2018
- 14:33 CoCoALib Design #925: MachineInt or long for args which are indices (yet again)
- Should indices be constrained to be non-negative?
Note that @symbol@ currently does allow negative "indices".
It ...

- 16:09 CoCoALib Feature #872: LinSolve for matrices over FFp
- I have implemented a version of "LinDepMill" for MatrixFp.
This should be a good basis for further impls.
Note ha...

- 18:16 CoCoALib Feature #658: Indets actually in a poly (or vector or matrix)

- 16:13 CoCoALib Support #1056: Release: CoCoALib-0.99560 (together with CoCoA-5.2.2)
- uploaded manuals to research gate
- 16:11 CoCoA-5 Support #977: "universal denominator" (related with GroebnerFanIdeals)
