Hi,
You can use simply a Newton method, it's easy for implementation and
enough good in the most of case. if you have the optimization toolbox
already installed then you can just use the function fsolve ( please read
the documentation in matlab help) if not you can use an algorithm which is
available online colled mmfsolve
(http://www.nd.edu/~wschnei1/Courses/CBE_445/Fall06/Lectures/Lecture2/mmfsolve.m).

nonlinear system algebraic equations

Hi Everybody,
I am dealing with a system of three nonlinear algebraic
equations (coming off fron a PDE once I truncate its
Fourier series solution at the second order).
Do you have any suggestions about how can I solve them?
Any useful Matlab routine or if some of you has a good
one...
Many thanks,
Francesco
