linear system, since there is no good algorithm for all the kinds of
nonlinear case. The most popular general way to solve the nonlinear system
is the so-called Newton Method, which solves a linear appoximation
subproblem iteratively to try to get close to the solution. Keep in mind
that the Hessian is required. You could compute it by finte difference or
use some Automatic Differentiation package. | S*M
