 Scipy has currently essentially no support for large-scale root finding,
 for problems where the Jacobian is known and sparse.

 The MINPACK codes work well with dense jacobians. However, a
 reimplementation (or another software package) of the same/similar trust
 region based method allowing sparse-matrix Jacobians would be necessary.
