Hi,
I am confused by the output of the hessenberg_form() method applied to a
symmetric matrix. In sage 4.8, the result is neither symmetric nor
tridiagonal.
For example, I unsuccessfully tried to replicate an example from
http://eigen.tuxfamily.org/dox/classEigen_1_1Tridiagonalization.html

Thank you Yann and Simon for your suggestions.
I think solve() may be too limited for my actual problem, but
augmenting the ideal with additional polynomials could work with a bit
of effort on my part.
Thanks again,
Ben

Hi,
I have a symbolic polynomial system that I would like to characterize
the roots of. Although I know that if there are any roots they are
real and positive, the polynomials involve square roots (of positive
quantities) and sage does not seem to like that and nor does it like
^(1/2). The followi

I am now trying to solve a system of equations using sympy instead of
Maxima to see if sympy's behavior is closer to that of Mathematica.
The following example is from the sympy tutorial (where i

Hi,
I maintain an R package, but there is one place where a symbolic
solution is needed to verify a result. I would like to write an R
function that prints proper SAGE input so that users can easily feed
it to SAGE. However, I have not yet been able to get SAGE to produce
the expected behavior fo
