There has been some discussion recently about what exactly is meant by supported
. I've put some notes on what I believe would be sensible wording to indicate
the level of support on platforms. All platforms name/versions are
semi-fictitious, as I've no idea what systems Sage is tested on. But i

Thanks for the good suggestions. The challenge is trying to recognize
the variables in derived expressions. I'm sure I can combine your
ideas to produce something suitable.
Thanks!

I know gcc 4.5 has bought some issues. Note however gcc 4.5 is not the latest
release. There may be some argument for not worring too much about gcc 4.5, and
let the gcc developers sort out some bugs.

I don't know if it is such a good idea worrying about gcc 4.5 just now. Note

I think Wikipedia has succeeded in making it easy for anyone to

Do you refer to the fact that the following fails:

Any chance of extending the default matrix methods
eigenvectors_right() and eigenvectors_left() functions to complex

I found the following which might be a basic approach?
