Hmmm... I will look into it. Anyway, it is not critical, since I
have firefox running almost all the time. If I find something, I will
let you guys know.
Thanks a bunch!

I just compiled from source; it took forever. THE PROBLEM IS NOW
SOLVED!!!
There is however another, independent issue.
Whenever I try to run sage -notebook or notebook() inside of sage, if
firefox is already running, it opens a new tab and everything works
nicely.
But if firefox is not alread

Hi,
I am trying to compute eigenvectors and eigenvalues of a matrix and I
don't understand the output.
sage: R=RealField(30)
sage: M=matrix(R,2,[2,1,1,1])
sage: M.eigenspaces()
[
(2.6180340, [
]),
(0.38196601, [
])
]
If "30" is replaced with "100" the second eigenspace gets printed out,
but

Don't think so! See IRC, thanks wjp! Why should Sage plot a

Please, in the future, include a little information with your
question. It is not easy to diag
I think it is pretty easy to make one using piecewise.

There is one in scipy, but that is not loaded by default. It might be
a good place to start; I think we should use scipy more by default
than we do currently.

ps. in case its not obvious, here's an example:
sage: import scipy
sage: map(scipy.sign,range(-3,3))
[-1, -1, -1, 0, 1, 1]

Yep, just noting that this has been requested before:
I think it would be nice to have a signum-function (i.e.
sign(x)=abs(x)/x or sign(x)=cmp(x,0) ) in sage.
There is none, right?
Of course it should work on integers, floats, lists, etc.

I want to plot a simple function: sqrt(1-x^2)
i tried plot(sqrt(1-x^2),(x,1,10)) and plot((1-x^2)^(0.5),(x,
1,10)) ,
but i doesn't work.
What i am doing wrong?
Thanks in advance

Hi,

Traceback (most recent call

should not be, or?

Hi,
start sage-2.10.1 in a directory which contains a subdirectory 'foo':
sage: a = srange(3)
sage: save(a, 'foo/foo')
sage: b = load('foo/foo')
sage: b
[0, 1, 2]
sage: save(a, './foo/foo')
