Skin weight optimization (matrix form) (3)

Matrix form second attempt

$$
\nabla \mathbf s_i \sum\limits_{j \in \mathcal N(i)} (c_{ij} \mathbf S_i) \vec w_i  - \nabla \mathbf s_i \sum\limits_{j \in \mathcal N(i)} (c_{ij} \mathbf S_j) \vec w_j  =  \nabla \mathbf s_i \vec b_i
$$

It would be interesting to express the above in terms of the Laplacian L and skinning matrix S.
