protectedvirtual

The matrix component of $\mathbf{R}$ is given by

$\mathbf{R^{T}_{v}}= -\mathbf{S}^{-1}_{ef,ef}\mathbf{S}^{T}_{v,ef}$

For every vertex mode we extract the submatrices from statically condensed matrix $\mathbf{S}$ corresponding to the coupling between the attached edges and faces of a vertex ( $\mathbf{S_{ef,ef}}$ ). This matrix is then inverted and multiplied by the submatrix representing the coupling between a vertex and the attached edges and faces ( $\mathbf{S_{v,ef}}$ ).

Reimplemented from Nektar::LocalRegions::Expansion.
