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

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.

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
