That's because you didn't try hard enough :-)

There are many operations in Sage that take a function/expression as
the first argument, and one or more variables with ranges as
subsequent arguments. The prototype is plot(x^2*sin(x),-4*pi,4*pi).
It would be nice if the syntax were consistent across all such
functions. There are already ticket

yeahr, well, i think it was somewhere else too, but i don't remember.
the point is, i think, that this

hi, i didn't read the patch and don't want to comment much,
In http://trac.sagemath.org/sage_trac/ticket/3704, the diagonal matrix
constructor is modified (and simplified/enhanced) to let someone do:
sage: diagonal_matrix(1,2,3)
[1 0 0]
[0 2 0]
[0 0 3]
to get a diagonal matrix with diagonal entries 1, 2, 3.
However, this conflicts with the previous sy
OK, I think I have fixed this.A patch is up at
http://trac.sagemath.org/sage_trac/ticket/4060 awaiting review.
I am cross-posting this to sage-devel to hopefully attract a
reviewer. In the meantime you could patch your own source if you'd
like. If you aren't comfortable doing that, you coul

Your construction gives a rank 1 matrix, so there's a double
eigenvalue of zero. The two eigenvectors which are found for that
eigenvalue need not be orthogonal, they are just some basis for the
eigenspace. The entries you thought should be zero are the inner
product of those eigenvectors with e

Hi,
the following code
b=matrix(3,1,[random() for i in [1..3]])
B=b*b.transpose()
lb,Sb=B.right_eigenvectors()
print lb
print
print Sb.transpose()*B*Sb
print
print Sb.transpose()*Sb
give's in my sage version 3.0.6 the following result:

Perhaps a trivial contribution, but I would like to give primes ideals
"human-readable" names such as P2a,P2b,.. for primes above 2, etc; so
then when I print a factorizaed idea I see something like
P2a^3*P2b*P17.
I suppose this idea would apply to other complicated structures too.
