This function tries to solve f(x) = 0, where f is a vector function. Uses Broyden's pseudo-Newton method, where an approximate Jacobian is updated at each iteration step, using no extra function evaluations. The optional bounds keep the search within a rectangular region.
fsolve from the optimisation toolbox is more robust but lacks the bounds option.
