19:30 CoCoA-5 Feature #90: Make the new fn CoefficientsWRT available in C5: In CoCoALib *@CoefficientsWRT@* accepts both a @RingElem@ and a _list of indets_ as 2nd arg, and produces the same ty... John Abbott
16:41 CoCoA-5 Feature #90 (Resolved): Make the new fn CoefficientsWRT available in C5: @coefficients(4*x^3+2*x+1, x);@ had been disabled.
Write @CoefficientsWRT(F, x);@ returning the coefficients of F wrt... Anna Maria Bigatti

18:24 CoCoALib Bug #277 (New): Eliminate class RefPPMonoidElem?: Recently I eliminated the class @RefRingElem@ for ring elements.
Should I do the same for *@RefPPMonoidElem@*?
Pres... John Abbott

15:00 CoCoALib Feature #127 (In Progress): Convert DUPFF code to C++: JAA has written a first prototype.
It works, but is 10% slower than the old C code for multiplication - why??? John Abbott
12:45 CoCoALib Feature #144 (Resolved): Buchberger-Moeller: generic impl: JAA has implemented a first prototype in CoCoALib.
It works on two simple examples. Still need to:
* make it accessi... John Abbott

09:49 CoCoA-5 Feature #78: Elim ordering and matrix ordering in CoCoA-5: *CompleteToOrd* gives a non-term-ordering if there are 0's in the given row.
I think it's easy to fix (in cocoalib). ... Anna Maria Bigatti
09:10 CoCoA-5 Feature #276 (New): TeXmacs interface: We still have problems about the graphical interface.
Can we easily get a nice interface with TeXmacs?
possibly usi... Anna Maria Bigatti

15:51 CoCoA-5 Feature #273 (In Progress): Package for Polynomial Algebra Homomorphisms: Giulia has done 4 examples.
For next time she will convert the code in the solutions into various functions (_e.g._ ... John Abbott
10:42 CoCoALib Feature #121: Porting "IdealOfPoints": I think that the good old code should be linked first.
Making a proper clean Chinese Remaindering in CoCoALib will r... Anna Maria Bigatti

18:46 CoCoA-5 Bug #275 (Closed): Unhelpful error messages when SmallExponent_t is unsigned char.: I changed @config.H@ so that the type @SmallExponent_t@ is @unsigned char@ (in an attempt to tackle Enrico Carlini's ... John Abbott

14:01 CoCoA-5 Feature #274: InputForm for output readable as input: We should probably avoid the name *@InputForm@*; in the past the people behind Mathematica have not hesitated to sue ... John Abbott
11:14 CoCoA-5 Feature #274 (In Progress): InputForm for output readable as input: Compare these... Anna Maria Bigatti
