nonlinear least squares - support for large sparse problems.

I would appreciate if someone could answer the following question for me: does the nonlinear least square solver has support for sparse problems? I mean, what if the optimization problem is large and the jacobian matrix is sparse (each row contains a few nonzeros). Some libraries, such as Matlab, give you handles so you can write a subroutineto compute theappropriatematrix-vector products instead of forming the Jacobian. Does Intel MKL have something like this?

Thank you in advance,

Gonzalo

Other than that, there is probably no provision for exploiting sparse structure.
