16:28 CoCoA-5 Bug #226: HilbertBasis segv: I further reduced the error:... Anna Maria Bigatti
16:01 CoCoA-5 Bug #226 (In Progress): HilbertBasis segv: Here is some "simpler" CoCoA-5 code which triggers the problem:... John Abbott
14:23 CoCoA-5 Bug #102 (Feedback): Packages: should exported functions be automatically "Protect"ed?: JAA notes that _system protected_ variables cannot be unprotected (_e.g._ the variable *@QQ@*).
Internally the inter... John Abbott
12:11 CoCoA-5 Support #296: Documentation for Parser/Interpreter: I have already assigned it to myself as I'm the one most using it Anna Maria Bigatti
11:42 CoCoA-5 Support #296: Documentation for Parser/Interpreter: I thought the most difficult question would be _who is going to do it?_
John Abbott
08:37 CoCoA-5 Support #296 (In Progress): Documentation for Parser/Interpreter: Even though the code is written quite well it would be handy to have some documentation ;-)
The most difficult quest... Anna Maria Bigatti
08:28 CoCoA-5 Design #294: BuiltInFunctions: General "OneLiner" for arguments of different type: Not quite the dream solution, but I found this function making life easier:
*@evalArgAsT1orT2orT3@*... Anna Maria Bigatti

17:42 CoCoA-5 Bug #102 (In Progress): Packages: should exported functions be automatically "Protect"ed?: After considering typical use patterns, it makes most sense for *@Export@* to protect the exported names, and for *@D... John Abbott
15:40 CoCoA-5 Support #293 (Feedback): Add CpuTime to C5 manual: Anna Maria Bigatti
14:50 CoCoA-5 Bug #226: HilbertBasis segv: If you run the two offending lines in a fresh CoCoA-5 then C5 reports an error that @CurrentRing@ has no value! This... John Abbott
14:43 CoCoA-5 Bug #100: BringIn should map only the indets in its arg: We need a sort of _partial_ canonical hom which maps symbols which are not in the codomain to zero. Before applying ... John Abbott
12:51 CoCoA-5 Design #294 (Closed): BuiltInFunctions: General "OneLiner" for arguments of different type: one liner functions work like a dream (thanks Giovanni! ;-)
Is it possible to simplify writing the code for _overloa... Anna Maria Bigatti
12:44 CoCoA-5 Feature #193: BuiltinFunctions.C getting too long (2000 lines): Splitting the code seems to work very well.
Now I wonder whether I should also split BuiltinFunctions separating the... Anna Maria Bigatti

18:17 CoCoA-5 Feature #200: add modules and module operations: added zero(module), BaseRing(module), RingOf(module), RingOf(ModuleElem)
added stub documentation
Anna Maria Bigatti
17:17 CoCoA-5 Feature #200 (In Progress): add modules and module operations: added types MODULE and MODULEELEM.
added functions: NewFreeModule, arithmetics for type MODULEELEM. Anna Maria Bigatti
17:19 CoCoA-5 Support #293 (In Progress): Add CpuTime to C5 manual: Anna Maria Bigatti
16:51 CoCoA-5 Support #293 (Closed): Add CpuTime to C5 manual: Add @CpuTime@ to CoCoA-5 manual.
Suggested keywords: time, cpu, timing, timer John Abbott
16:37 CoCoALib Feature #229: Generator for random ring elements: Is this true? do we really need it?
I suggest we remove this issue.
Anna Maria Bigatti
15:21 Bug #238: Cleaner CVS?: Another little argument for my point:
@make veryclean; cvs up@
gives warnings like
@cvs update: warning: `includ... Christof Soeger

18:27 CoCoALib Feature #278 (In Progress): add CoeffVecWRT to cocoalib: The function *@CoeffVecWRT@* has been implemented (and documented).
Needs testing.
John Abbott
16:36 CoCoALib Design #291 (Feedback): NewZZmod and NewRingFp: improve manual, clarify implementation: Added comment to doc files. John Abbott
15:30 CoCoALib Feature #144 (Feedback): Buchberger-Moeller: generic impl: Improved impl to handle case where NumPts differs from NumIndets.
Added *@IdealOfPoints@* to CoCoA-5.
Added a test ... John Abbott
15:21 CoCoALib Feature #123: IdealOfPoints with generic coeffs: A reasonable outline of algorithm is:
# Choose a suitable homomorphism (to a prime (finite?) field?).
# Compute bas... John Abbott

19:18 CoCoALib Feature #51: polynomial coefficient extraction w.r.t. variable: After verbal discussion with Anna, we decided that we prefer that the "terms" in the result be in *decreasing order o... John Abbott

18:15 CoCoA-5 Design #292 (Closed): Rename IndetsCalled to indets: Rename *@IndetsCalled@* to *@indets@*.
Non-trivial because there is already a fn called *@indets@* John Abbott
15:24 CoCoA-5 Feature #273: Package for Polynomial Algebra Homomorphisms: Giulia has produced a first version of the code for phi: R/I --> S/J.
For next time she will:
* change the ring name ... John Abbott

09:32 CoCoALib Feature #51: polynomial coefficient extraction w.r.t. variable: I think that, by its current implementation, the order of the elements in the result of *@CoefficientsWRT@* is set (i... Anna Maria Bigatti

18:37 CoCoALib Design #291 (Closed): NewZZmod and NewRingFp: improve manual, clarify implementation: For small primes p the functions *@NewZZmod(p)@* and *@NewRingFp(p)@* are equivalent (or not?).
I think that should ... Anna Maria Bigatti
