Multilevel matrix. This matrix stores an MGLevelObject of LinearOperator objects. It implements the interface defined in MGMatrixBase, so that it can be used as a matrix in Multigrid.

inline |
Constructor setting up pointers to the matrices in M
by calling initialize().
Definition at line 233 of file mg_matrix.h.
