16:16 CoCoA-5 Feature #912: Add TUTORIALs to online manual
- I have added some hasty tutorials... no doubt it is clear that they have been hastily written.
21 Feb 2017
-
- There is less than a week to go to the mini-course. It would be nice to make some progress with the tutorials.

08:00 CoCoALib Slug #777: SLUG: elimination

I think @myFinalizeGBasis@ can be improved...

- 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
14 Feb 2017
-
- Checked-in an update to all Makefiles. Hope it works -- I did mess some things up :-(

- 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 maybe it does not mak... -
