Problem on solving nonlinear algebraic equations

I'm trying to solve a nonlinear algebraic equation set with 16 eqns. The problem is that these equations are highly ill-conditioned. (Coefficients for some equations are 10^8 larger than others )

I've tried "fsolve" to solve it, but it's not working.

Is there any options in fsolve to deal with ill-conditioned equations?

Thanks!!!

Any help?

Perhaps move it to within MuPad and do the solve() computation with Digits set to a significantly higher number?

The result will still be extremely sensitive to perturbations in the original data, but you will at least be able to get a result.
