[sage-support] notebook: sidebar hidden by default
The notebook now hides the nav sidebar by default.

[sage-support] Re: fortran error on fedora
Several people are having trouble building quaddouble, so I'm going to release a sage-2.1.1 that has it removed (it'll be optional). It's really not crucially important to include it in SAGE. -- William On Fri, 09 Feb 2007 06:21:37 -0700, carlM [EMAIL PROTECTED] wrote: Latest update fails to build on fedora6, fortran compiler internal error. tail of make output: Making install in fortran make[2]: Entering directory `/mnt/extra/hcmeyer/sage/sage-1.5/spkg/ build/quaddouble-2.2/src/fortran' f95 -O2 -ffree-form -c -o ddmod.o ddmod.f ddmod.f:0: internal compiler error: Illegal instruction Please submit a full bug report, with preprocessed source if appropriate.

[sage-support] Search and info include non-SAGE functions
I had a question about nth roots. I did not know about nth_root. I tried searching for root, nth, and n using tab but did not find nth_root. Also nth_root? gives me nothing. It is kind of confusing for me. --~--~-~--~~~---~--~~ To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://sage.math.washington.edu/sage/ and http://sage.scipy.org/sage/ -~--~~~~--~~--~--~---

It's a function of associated with an object, so you have to have your
obejct first. For example, if you want to find the cubic root root of
512, you do something like this:
{{{
sage: e=512
sage: e.nth_root(3)
8
}}}
Hope that made sense,

Does SAGE support finding the nth root of something?
The cube root of 27 is 3, 8 is 2, 64 is 4
One way is
ZZ(gap.eval(RootInt( 64, 3 )))
Or:
(x^n-a).roots()[0][0]
Or
{{{
sage: exp(log(64)/3)
4.0
}}}

This is because we are now using the amazing linbox linear algebra, and it makes some sort of assumption about the BLAS you're using, which isn't satisfied. Are you using RHEL or Fedora Core? Somebody else using Fedora Core had the same problem as you. My current plan is to install FC on a machine and see if I can replicate the problem, so I can fix it (possibly by changing linbox to not use that blas function).
