16:57 CoCoALib Feature #337: Module homs
- To create a module hom from @M1@ to @M2@ we must specify where each generator of @M1@ maps to. These could be specif...
-
- OK, I have modified *@configure@* in the CoCoALib root directory.
Let me know if it does what you expect.

Perhaps you mean that there are severa... -
- I thought that, with many BOOST to choose from @configure@ should give a warning (and a choice).
Apparently it doesn... -
16:01 CoCoALib Support #302: Compilation on M$Windows: Visual Studio
- To the last problem for Windows 64:
size_t is there unsigned __int64, but long is still 32bit. I guess that is causi...

- @DenseUPolyClean@ uses @std::size_t@ both internally and in fn interfaces.
Is this really appropriate? If not, re... -
- My old impls in CoCoA-4 returned a matrix as the result: the entries in the matrix are the coeffs of the basis elemen...

- First try in public version 10.6.

-
- Implement module homs.

- Giulia has done:
* not much (because the module impl had too many holes)
For next time she will:

- New module fns to add:
* @rank@
* @IsIn@
* equality test
-
- Make equality testing of two (sub)modules work as it does for ideals
(_i.e._ using G-bases check both inclusions).

- It is not easy to obtain the manual page for the logical operators @and@, @or@, @not@.
Can it be made easier?

- I'm not sure which version of *redmine* we are using, but a new stable release was announced just a week ago. Should...

- JAA has just changed slightly the way matrices are printed: removed two newlines.
The newly changed code would produc...

- This is a silly mindless task, but it needs to be done (and the sooner the better).
-
- Just a pointless comment to "wake up" this issue.
-
- All calls to @convert@ have been eliminated (replaced).
The conversion from @BigInt@ and @BigRat@ to @string@ has ... -
- I have just added the approx pts preprocessing fns to CoCoA-5.
This issue is about deciding the most appropriate int... -
- JAA has added a new class *@StdDegRevLex2@*.
This appears to offer a cleaner and faster impl -- but its speed has ye...

Modified the doc for the conversion functions.

- JAA has improved the doc for the type conversion fns @convert@, @IsConvertible@ and @ConvertTo@.
Still to be done:... -
- Revised interface now works well in the context of @DUPFp@.
Updated all 3 impls, and their doc.
Perhaps revise im...

- I've rewritten most of the @DUPFF@ code in C++ (_i.e._ using @DUPFp@).
Still need to do:
