M is a symmetric rank 2 tensor, r is a vector.

The integral is as follows

[tex]\int_{\partial V} (\textbf{r} d \textbf{S} \cdot \textbf{M}+d\textbf{S} \cdot \textbf{Mr})[/tex]

I need to somehow manipulate this to get [tex]\int_V {\{\nabla \cdot \textbf{M})\textbf{r}+\textbf{r}(\nabla \cdot \textbf{M})+2\textbf{M}\}dV}[/tex]

Thanks
