- Anna implemented a quick fix: it was much faster, but would also sometimes give a wrong answer (we understood why).

15:29 Slug #1629: RingElem slow with many indets

- The global @packageDir@ should probably also be of type @boost::filesystem::path@.
Currently it is @std::string@ a... -

Anna asks whether we should start compiling with standard ... -

If we prefer MAT, are the eigenvectors the rows or the columns? ... -

Just some suggestions.... maybe t... -
- Done for the CoCoA-5 menu.

- it is probably easy to add it to the cocoa5-comint menu.
What about the keybinding?

- Website seems ok now.
Closing.

-
- No longer crashes. So that's good.
Now we just need to clean up the path, but that's in a new issue #1631 -

- We probably need to change the fn @CoCoAManFileName@ (around line 950 in @OnlineHelp.C@).
The return type should be ... -

- It would be nice (& cleaner) if we could get rid of @packages/../@.
I think this should be possible.
