It probably even is more powerful and general, but we +chose to introduce this material here anyway to demonstrate how to work with +block matrices and to develop solvers and preconditioners, rather than using +black box components from the library. + +For those interested in looking up the corresponding library classes: the +\texttt{InverseMatrix} is roughly equivalent to the +\texttt{PreconditionLACSolver} class in the library. Likewise, the Schur +complement class corresponds to the \texttt{SchurMatrix} class. + \subsection*{Definition of the test case} -- 2.39.5
