Hello,
I have a system of quadratic equations (results of a Hamiltonian optimization)
which I need to find the roots for. Is there a package and/or function which
will find the roots for a quadratic system?
Certainly you cxould use solve, see
?solve
Alternatively you could go for a computer algebra system with an implemantation
of groebner basis, and use an symbolic method.
I have looked into using solve. However, solve works on a system of linear equations (at least that is how I read it). I have a system of quadratic equations. They can be written to equate to zero, so that a non-linear system solver should do the trick.

Note that I am not opimizing, but
rather solving the first order conditions which come from a Hamiltonian. I am
basically looking for something in R that will do the same thing as fsolve in
Matlab.
Thanks,
John.
