Hi Johan,
2010/4/27 Johan Grönqvist<johan.gronqv...@gmail.com>:
The current documentation of norm() on complex numbers can be accessed
from the Sage website [1]. That documentation leaves much to be
desired, even though it makes the distinction between the complex norm
and the absolute value of a complex number.
That documentation is much better than what I looked at. That certainly
satisfies my request for documentation.
Would you upload a patch
to the trac server to improve that documentation? If so, please CC me
on the relevant ticket and I'd be more than happy to review your
patch.
I would like to improve the following case.
----------------------
sage: norm?
Type: function
Base Class: <type 'function'>
String Form: <function norm at 0x1787938>
Namespace: Interactive
File:
/home/johan/Debian/sage-4.4.rc0/local/lib/python2.6/site-packages/sage/misc/functional.py
Definition: norm(x)
Docstring:
Returns the norm of x.
EXAMPLES:
sage: z = 1+2*I
sage: norm(z)
5
sage: norm(CDF(z))
5.0
sage: norm(CC(z))
5.00000000000000
-------------------
In particular I would like it to remark that the norm of the one element
vector is not the same as the norm of the element (for a complex number).
I hope to look at it later this week.
Thanks for your reply
Regards
Johan
