17:54 Bug #1014 (In Progress): RowMat, ColMat with arg an empty list/vector
Another (mild?) incompatibility is that in CoCoA-5 @RowMat@ and @ColMat@ accept as input lists of INT and/or RAT.
In...

17:49 Bug #1014: RowMat, ColMat with arg an empty list/vector
At the moment JAA thinks that giving an error is probably better.
Is there a situation where one might reasonably ...

17:45 Bug #1014: RowMat, ColMat with arg an empty list/vector
In CoCoA-5 one can call @RowMat([])@ and @ColMat([])@ to produce a matrix 1x0 or 0x1.
In CoCoALib a similar call pro...

17:39 Bug #1014 (In Progress): RowMat, ColMat with arg an empty list/vector
What should @RowMat@ and @ColMat@ do if given am empty list/vector as argument? John Abbott
17:51 Feature #202: MatrixView/function for viewing a single row or column (RowMat, ColMat)
What should these functions do if the matrix is 0-by-C or R-by-0?
Return a 0-by-1 or 1-by-0 matrix?
John Abbott
17:42 Feature #202: MatrixView/function for viewing a single row or column (RowMat, ColMat)
Another possibility: uglier, but possibly clearer?
* *@RowMatView@*
* *@ColMatView@*
The intention is that the r...

14:16 Support #1013: GlobalManager: name of object in examples (and tests)
In just a couple of days I shall have to present CoCoALib and its examples.
Indeed, I shall probably concentrate on ...
John Abbott
14:13 Support #1013 (New): GlobalManager: name of object in examples (and tests)
At the moment all CoCoALib examples use the name *@CoCoAFoundations@* for the @GlobalManager@ object.
Is there a b...

13:40 Feature #872 (In Progress): LinSolve for matrices over FFp
Currently I am just adding the "keyword" *@MatrixFp@*
Some code has already been written, and it is in the file @sr...

13:23 Feature #82: C++11 compatibility questions
How does this issue differ from issue #83? John Abbott
13:19 Feature #1010: C++11: Mario's Hilbert scheme code
Mario makes essential use of various C++11 featues (_e.g._ @auto@ variable declarations).
The problem is that CoCo...

13:14 Feature #1010 (New): C++11: Mario's Hilbert scheme code
Mario would like to incorporate his Hilbert scheme code, but to do so he must compile with c++11 (because he uses sev... John Abbott
13:12 Support #861: Janet basis code: TmpJB files give some problems with C++11 (using CLANG/LLVM)
@Winfried: could you check whether this problem persists in the latest version of CoCoALib?
There is version from 16...

08:00 Slug #777: SLUG: elimination
Apart from the improvements we can do for @elim@ (and are about to do ;-)
I think @myFinalizeGBasis@ can be improved...

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...
John Abbott
13:14 Slug #777 (In Progress): SLUG: elimination
I happened upon the file for the example, and tried it with @SetVerbosityLevel(1999)@.
It seems that much of the tim...

12:45 Feature #962: General verbose mode?
How about starting with just two ranges?
1--9 for users
10--??? for CoCoA packages and CoCoALib
I had also consi...
John Abbott
08:36 Feature #962: General verbose mode?
I prefer the mnemonic number of digits. So I suggest
1 digit -- free for users
2 digits -- cocoalib and cocoa pac...

18:40 Feature #962: General verbose mode?
Anna's idea of reserving certain ranges for different "levels" of function appeals to me. I think her ranges are too... John Abbott

All tests pass. I have now checked in the change. ==> feedback

14:47 Bug #1004 (Feedback): In scripts: use portable test for absolute paths
No problems has been reported so far, so moving to "feedback".
I think the solution I have chosen should be compat...
John Abbott
14:44 Feature #1008 (Resolved): square function
OK, then we agree to eliminate the function @square@. It will disappear the next time I do a check in (later today?)
John Abbott
09:44 Feature #1008: square function
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...

16:20 Feature #1008 (In Progress): square function
So far we have not really felt the need for a @square@ function in CoCoALib (presumably).
So maybe it does not mak...

16:19 Feature #1008: square function
A search for @square@ showed that there had been a @square@ function for @RingElem@, but that it was removed (presuma... John Abbott
16:14 Feature #1008 (Closed): square function
In @utils.H@ there is a fn called @square@ defined only for @double@. It used only in @ApproxPts.C@.
I am sure th...

17:33 Feature #962: General verbose mode?
I think we should set some rules like:
1 - 9 (or to 99) reserved for users.
100 - ?? for higher cocoa/cocolib fu...

16:43 Feature #1005 (Closed): Makefile: install target for CoCoALib
There should be an *@install@* target for CoCoALib.

Anna reports that the modified script worked as desired on M$ plaform.
So I have changed the other scripts (which ne...
