Detailed Description

template<class MATRIX>
struct AppFrame::MatrixBlock< MATRIX >

A wrapper around a matrix object, storing the coordinates in a block matrix as well.

Note

They are the position in the global matrix, where I don't use BlockSparseMatrix. Matrices may have the same coordinates for the following reason: A preconditioner for the Oseen system can be built as a block system, where the pressure block is of the form M^-1 F A^-1 with m the mass matrix (u,v), A the Laplacian and F the advection diffusion operator. So, I need to build three matrices for a single block in my system + in some cases a pressure stabilization.
