So: we have an eigenvalue! To nd the Schur decomposition of A, we now need to nd all of the eigenvectors corresponding to the eigenvalue 9. As shown above, this is just the space E 9 = f(x;y;z) jx+ 2y+ 2z= 0g: We want an orthonormal basis for this space. To do so, we rst nd a basis, and then use Gram-Schmidt.

To paraphrase Shakespeare's Juliet, that which - ilie Haynsworth called the Schur complement, by any other name would be just as beautiful. Från baksidan.

Hi, Please see my comments below. Thanks, Alex - I understand that the Schur complement matrix is obtained in the solution vector. I had a look on PARDISO 5.0 (not the Intel software) documentation and the SCHUR complement is returned as a sparse matrix.

Featured on Meta Stack Overflow for Teams is now free for up to 50 users, forever Then the Schur complement of the block D of the matrix M is the p × p matrix, A-B ⁢ D-1 ⁢ C. Analogously if A is invertible then the Schur complement of the block A of the matrix M is the q × q matrix, D-C ⁢ A-1 ⁢ B. Allora si definisce complemento di Schur del blocco D della matrice M la matrice di aspetto p×p A − B D − 1 C {\displaystyle \,A-BD^{-1}C} .

We present a new substructuring approach for solving stiff multibody systems containing both bilateral and unilateral constraints. Our approach is based on non-overlapping domain decomposition with the Schur complement method, which we extend to systems involving contact formulated as a mixed bounds linear complementarity problem.
