Multilevel matrix selecting from block matrices. This class implements the interface defined by MGMatrixBase. The template parameter MATRIX should be a block matrix class like BlockSparseMatrix or BlockSparseMatrixEZ. Then, this class stores a pointer to a MGLevelObject of this matrix class. In each vmult, the block selected on initialization will be multiplied with the vector provided.

| ) |
Constructor. row and col are the coordinate of the selected block. The other argument is handed over to the SmartPointer constructor.

| void MGMatrixSelect< MATRIX, number >::set_matrix | ( | MGLevelObject< MATRIX > * | M ) |
Set the matrix object to be used. The matrix object must exist longer as the MGMatrix object, since only a pointer is stored.
