13:27 Slug #1009 (Closed): coefficients for MinPoly e Frobenius
- The function creating the vector of coefficients (wrt a QB) can be improved.
(this is an internal and costly functio... -
13:17 Slug #777: SLUG: elimination
- The same example computed using @MinPolyQuot@ is much faster: about 0.2s :-)
Maybe @elim@ can be programmed to us... -
- I happened upon the file for the example, and tried it with @SetVerbosityLevel(1999)@.
It seems that much of the tim... -
- How about starting with just two ranges?
1--9 for users
10--??? for CoCoA packages and CoCoALib
I had also consi... -
- I prefer the mnemonic number of digits. So I suggest
1 digit -- free for users
2 digits -- cocoalib and cocoa pac...

- Anna's idea of reserving certain ranges for different "levels" of function appeals to me. I think her ranges are too...
-
- All tests pass. I have now checked in the change. ==> feedback

- No problems has been reported so far, so moving to "feedback".
I think the solution I have chosen should be compat... -
- OK, then we agree to eliminate the function @square@. It will disappear the next time I do a check in (later today?)
-
- If we had a @square@ we should document how it differs from @power(x,2)@. So I think we'd better not.
If we have @m...

-
- So far we have not really felt the need for a @square@ function in CoCoALib (presumably).
So maybe it does not mak... -
- A search for @square@ showed that there had been a @square@ function for @RingElem@, but that it was removed (presuma...
-
- In @utils.H@ there is a fn called @square@ defined only for @double@. It used only in @ApproxPts.C@.
I am sure th...

- I think we should set some rules like:
1 - 9 (or to 99) reserved for users.

-
- There should be an *@install@* target for CoCoALib.

So I have changed the other scripts (which ne... -

- I set verbosity level to 1965 then tried calling @ImplicitHypesurface@ with the option @ElimTH@, but no verbose messa...

- At this point I do not see any purpose in keeping even the option to extract compilation flags from @gmp.h@, so I now...

- One thing which puzzles me is that CoCoALib compiles fine and all tests pass on my old MacBook even without *@-m64@* ...
-
- I have changed it on my machines, but cannot currently check in (because cannot make VPN connection).

- After thinking about having to compile+install CoCoA/CoCoALib on numerous recent Linux boxes for the upcoming CoCoALi...

* *@ApproxPts2.C@*
* *@OpenM... -

I suggest postponing for a later release (unless you think that this is almo... -
- I have done some cleaning in @MatrixForOrdering.C@, but more still really ought to be done.
After 3 months in feed... -

- I note that the compilation flag *@-std=c++03@* will cease to be relevant (and may even become "harmful") once we upd...

- Here are some ideas:
* write a fn @IsCyclotomic@ for univariate polynomials (based on paper by Bradford+Davenport)

- Collect here ideas for potential student projects based on CoCoALib.
-
- The compilation flag *@-std=c++03@* is not recognized by the old g++ (version 4.2.1) on my old MacBook Pro, so causes...
