Hello everybody !!!
I would like to solve a set of equations with a very easy shape. My
equations are defined on variables p1_x, p1_y, p2_x, p2_y, ..., and I
would like to obtain values for them satisfying constraints like :
|p1 - p2| 1, i.e. (p1_x - p2_x)^2 + (p1_y - p2_y)^2 1
or something
Couldn't you use SCIP for this?
O probably !!
I will take a look at its documentation :-)

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
If no-one can answer this question, does anyone have an idea of another forum
where people may know the answer?
Thanks! -Emil
