with C = C T, A = A T, D = D T . Applying Schur complement with respect to A − B D − 1 B T yields In der linearen Algebra bezeichnet das Schur-Komplement eine Matrix, die sich aus den einzelnen Blöcken einer größeren Matrix berechnet. Das Schur-Komplement ist nach Issai Schur benannt. So: we have an eigenvalue!

The Schur complement is named after Issai Schur who used it to prove Schur's lemma, although it had been used previously.

To use Schur complement functionality you need to: Set iparm(36) to 1 if you want to calculate Schur complement only, and to 2 if you want to use computed factorization of initial matrix (A) during the solver step.
