#6109: [with patch, needs review] Bring documentation for QQbar up to 100% and
add
to reference manual
---------------------+------------------------------------------------------
Reporter: cremona | Owner: tbd
Type: defect | Status: new
Priority: major | Milestone: sage-4.0.1
Component: algebra | Keywords: QQbar documentation
---------------------+------------------------------------------------------
Comment(by cremona):
Suggestion for Carl: I think that the functions norm() and conjugate() on
QQbar are not very useful. I would change the name of conjugate() to
complex_conjugate().
I would like to see new functions conjugates(), norm(), trace():
* a.conjugates() returns a.minpoly().roots(QQbar,multiplicities=False)
* a.norm() returns a.minpoly().constant_coefficient() (* correct
sign)
* a.trace() returns -a.minpoly().coeffs()[a.degree()-1]
The more I look at qqbar.py the more impressed I am!
John
