Unconstrained nonlinear least-squares with small residuals can be
handled using fsolve (overdetermined nonlinear eq. systems)
since 3.1.55. For constrained optimization, sqp can be used. Another
option is to use the optim package, which provides a plethora of other
options, most well-known of which is leasqr.
