I think many fellow researchers are in the mailing list and maybe tired of
matlab. So maybe we can form a group to design the

`Actually I wrote a pretty generic Non-Linear Sparse Least Squares

``using manifolds, i.e. somewhat elegantly handling things like
``3D-orientations)

`It's originally based on some hand-coded small-size types and CXSparse

``I recently ported it to use Eigen::Matrix and Eigen::Quaternion,

``update it at [1].
``I don't want to make the current code toooo publically available at the

``could send a link to the current development to interested users.
