Schur complement for inverting block matrices
Let \(M\) be regular (i.e. invertible, as defined in Hackbusch's book [Hie]) and \(M = \left( \begin{array}{cc} M_{11} & M_{12}\\ M_{21} & M_{22} \end{array} \right)\). To calculate the inverse of \(M\), perform the standard manuaSchur complement for inverting block matrices
