- 10:28 Feature #1299: New fn ConstantTerm?
- I have a prototype impl, much like the impl for *@HomogCompt@*.
It is disappointingly slow for larger polynomials:...

- 21:49 Feature #1299: New fn ConstantTerm?
- This is a little bit like *@HomogCompt(f,0)@*. See issue #1439.

- The section in the web page with "Notes" looks a bit strange: _e.g._ "New and renamed files" seems to have two empty ...
- 13:04 Feature #1395: SHA checksum for released code
- I suggest putting the SHA-256 checksum in the "Notes" section on the web page for source releases.
Probably the best...

- 22:28 Bug #1264 (Closed): Remove unnecessary files before making CoCoALib release TGZ files
- John checked
- 14:50 Design #1446: Start using C++14 "move" capability
- We need to do this piecemeal as many different classes must be considered. Besided modifying the class, we will prob...
- 14:46 Design #1446 (In Progress): Start using C++14 "move" capability
- C++14 (maybe even C++11?) offer an appealing notion of "move ctor" which avoid some deep copies.
We should adapt o... - 14:39 Bug #591: Problem with template instantiation and order of include directives
- What should we do with this issue? The correct "solution" is for us to learn the foibles of C++.
It does highlig... - 14:34 Support #861: Janet basis code: TmpJB files give some problems with C++11 (using CLANG/LLVM)
- What is the status this issue? Is it now fully resolved?
Anna succeeded (2020-03-11) in compiling on her Mac, pres...

- 17:42 Feature #1395: SHA checksum for released code
- adjusted the page and the release-xxx.sh file to produce the correct files and instructions for publishing.
- 12:26 Feature #1395: SHA checksum for released code
- I think I might be slightly confused. What I wrote above in comments 11 and 12 actually refers to the "binary" relea...

- 15:47 Feature #1444: HNF: Hermite Normal Form
- Florian has already put a prototype impl (CoCoA-5) in issue #1304. This should be ported to C++.
NTL has HNF whic... - 15:43 Feature #1444 (New): HNF: Hermite Normal Form
- It would be nice to have HNF in CoCoALib.
I can see two cases:
* *(special)* over @ZZ@
* *(general)* over a more... - 15:39 Feature #206: Matrix equation solving: LinKer

- 16:31 Feature #1395 (Resolved): SHA checksum for released code
- I have also added a quick check that there are no writable files in the subtree to be released.
I have modified @r... - 15:26 Feature #1395: SHA checksum for released code
- So far I have made a small change to @release-linux.sh@.
I have added a line after the @MakeTGZ@ line:... - 16:01 Bug #1264: Remove unnecessary files before making CoCoALib release TGZ files
- I'll check once we have a source TGZ release. When that is clean, I'll close this issue (hopefully today or tomorrow...
- 10:36 Feature #1441 (New): GFan: port CoCoA_5 functions into CoCoALib
- Many useful GFan-based functions are implemented in CoCoA-5.
Port them into CoCoALib.
- 10:25 Support #1338: Release CoCoALib-0.99700
- updated starting page: https://cocoa.dima.unige.it/redmine/

- 08:51 Feature #1212: New function: GBasisByHomog
- Notes for me. In general: M matrix ordering.
If first row of M all positive
m m m 1
M 0
otherwise

- 17:41 Feature #1434 (Closed): GBasisByHomog for DegLex

I had some problems in finding the correct functions to make the matrix.
I'll write some notes about making t... - 16:35 Feature #1427: New function: LawrenceMat

It seems more "natural/efficient" to me than necess... - 15:43 Feature #1427: New function: LawrenceMat

I found a paper on ArXiV: @arxiv.org/pdf/1508.05461.pdf@ which gives... - 16:19 Feature #1395: SHA checksum for released code
- If we want to do this, we should delay the release a few days, so we can find out what to do.

I had accidentally introduced a race condition. Now it should be fine.
