Everything seems correct. So I've thought, Sage doesn't succeed to
locate the fortan compiler and thus I must explicitly set the two
environment variables. Or is it a problem of gfortran version ?
It looks to me

I do not fully get your example and I might be wrong, but I have the
feeling you are looking for the inverse survival function, i.e.

If you look at the source code (line 400 of sage/structure/
factorization.py) you can see how Sage compares a Factorization object
with something else:
(1) If the other thing is not a Factorization it will give false; else
(2) it compares the expansions of both (i.e. multiplies them out

dear all,
I try to install sage on a intel mac running osx 10.4.11. I didn't
find a binary for 10.4 on the website although it is stated that 10.4
is supported. So I tried with the disk image sage-4.3.3-OSX-32bit-10.5-
i386-Darwin.dmg
I followed the install instructions but when I try to start
Can anyone point me to the part of the Fine Manual which describes
how to set up Sage to let users not on the Sage server access via HTTP
(I.e. 'http://192.168.1.99:8000') ? ?
TIA

I think it is easier if you just type notebook?
Many thanks.

Start the Sage command line interface
I'm not suggesting multiplying it back out, but that if comparing to a
polynomial and the factorization has only one term, compare the
polynomial to that single term. I didn't know about the
is_irreducible() function, lol. Guess that would have worked best for
what I needed.
I think the code that
Dear all,
I try to find the eigenvectors of a general 2x2 matrix using
var('a,b,c,d');show(Matrix(2,2,[a,b,c,d]).eigenvalues());
show(Matrix([[a,b],[c,d]]).eigenvectors_left())
The eigenvalues are ok, but I get an error for the eigenvectors.
What am I doing wrong here ?

In a sage function I need to use Sage's built-in types, say, vector.

a=v(bar)
How do I find out from where it has to be imported?
(I haven't come up with anything better than running a grep on devel/

I'm not sure this is the best answer, but you could do:
A = matrix(SR,[[a,b],[c,d]])
v1,v2 = A.eigenvalues()
show((A-v1).left_kernel().basis()[0])
show((A-v2).left_kernel().basis()[0])
Perhaps part of the issue is that these do not have to be distinct.
