15:57 CoCoALib Slug #129: Better GCD
- (copied from some old handwritten notes)
GCD univ over QQ and ZZ (with normalization)
............. Fp (... -
15:25 CoCoA-5 Support #290 (In Progress): Which functions are defined in CoCoALibSupplement?
- Note for AMBigatti: explain the philosophy of what goes where.

-
- The unified documentation had not been finished. It is now much better, and can be regarded as good enough (though s...
-
- Is it worth adding a new fn *@PrimeField@*?
@PrimeField(0)@ gives @RingQQ()@
@PrimeField(p)@ gives @NewZmod(p)@

- Giulia has done several examples in quotients of polynomial algebras.
She had various questions (mostly related to f...

-
- Add documentation to show how to create a @DynamicBitset@ from a polynomial (which happpens to be a monomial). All y...

-
- Added tests for various functions related to continued fractions. As a consequence, I found another bug (and fixed it).
-
- Here is a simplistic solution: print all the "stack backtrace" information to a @string@. If the error is caught som...
-
- It seems difficult to do because the error is actually dealt with by a proper C++ *try*, whereas printing (the error ...
-
- When using the flag *--fullCoCoALibError* CoCoA-5 prints the full CoCoALib error message.
It does so even inside t... -
- I have added a new file *@INSTALL-cygwin@* in the CoCoA root directory; it contains a summary of various hints for pr...
-
- I describe here an easy way to check a list of tests (from @CoCoA-5/tests/anna.cocoa5@):...
-
- What about this?
(note that, as said above, all other error information is lost :-( )...

-
- When developing and changing a cocoa function it is useful to repeatedly run some tests.
Explain how to do this easily. -
- JAA has changed the names (as agreed in point 2). Also changed doc.
Fixed a bug -- it gave the wrong answer for a...

- Giulia has finished the implementations for the easy case (polynomial algebras). There was some discussion of *@IsIn...
-
- What is the correct way to write a CoCoA-5 test which checks that a certain call produces the expected error? It sho...

- When adding or removing files from *CoCoALib-0.99NN/doc/txt* there are a few operations to do in *@doc/aux-txt2tags@*...
-
- Giulia showed her restructured code: generally very good, just a few minor criticisms were made.
For next time, she ...

- In file *BuiltInOneLiners* there are many function wonderfully declared in one line.
Unfortunately sometimes we need... -
- JAA has implemented the fn in CoCoALib, and also make it available in CoCoA-5.
It remains only to decide the name(s),... -
- Proposals for the name of the function:...
-
- JAA proposes a function *@SimplestRationalInInterval@* which makes publicly accessible a feature already used interna...
-
- Add a new function which computes a good rational approximation within a specified *absolute* error. Laura needs thi...
-
- There are other cases: now I'm working on a (private) file with *GBEnv* and the function to get it form an object is ...

- AMB will unify the documentation files -- and update the names of the random sequence classes!
JAA will unify the co... -
- Approved the idea of *unifying the sources* after verbal discussion.
The best unified name seems to be *@random@*. -
- Discussion via Skype:
instead of *sample* use *NextValue* to access a new element from a *RandomStream..* -
- Following Alessandra Caleo's criticisms (see issue #75), we have modified the documentation and examples to make them...
-
- An idea: since *@IsPrime@* can be extremely slow for larger inputs, and since *@IsProbPrime@* is normally extremely r...

-
- Now calling *ZZ/(7)* twice produces two different rings.
Maybe that should be stored into GlobalManager.

-
- Alessandra reports:
* what does @flush@ do in @ex-GMPAllocator2.C@? (*ok, fixed now*)
* @ex-NF.C@ not mentioned in d... -

- I believe the problem is in lines 697-698 when the value for @par@ is computed.
It is not clear to me how the value ... -
- I believe the Emacs code for C/C++ is in @cc-mode.el@. On my computer the full path is:
*@/usr/share/emacs/22.1/lis... -
- I have had a quick look at the Emacs LISP source code. It is not terribly readable. I believe the relevant function...

- Write C++ code for *@CoeffVecWRT@*, corresponding to the cocoa-5 function CoeffListWRT (with indices shifted by 1, as...
-
- I added *@CoeffListWRT@* to @NotBuiltin.cpkg5@.
Added and fixed manual for @CoeffListWRT@, @coefficients@, @Coefficie... -
- Last night I tried compiling CoCoALib on my old Mac G5, and the compiler reported a problem in @TmpJBSet.H@ -- the da...

- In CoCoALib *@CoefficientsWRT@* accepts both a @RingElem@ and a _list of indets_ as 2nd arg, and produces the same ty...
-
- @coefficients(4*x^3+2*x+1, x);@ had been disabled.
Write @CoefficientsWRT(F, x);@ returning the coefficients of F wrt... -
- Giulia has converted her code into functions. The code performs some sanity checks on the arguments, but she was una...
