Then the Schur complement of the block D of the matrix M is the p×p matrix − − . It is named after Issai Schur who used it to prove Schur's lemma, although it had been used previously. Emilie Haynsworth was the first to call it the Schur complement.

## 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.

I want to apply the Schur complement to one element of a block matrix. What I do not know is how to organize the resulting values inside the new matrix.

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

motion for n = 1:N-1 % index for poses k = k+1; % add one factor J(k,n) = rand; % we simulate a non−zero block with just one scalar J(k,n+1) = rand; end % 2. landmark observations The Schur complement helps with the closed form derivation but isn't necessary. It's just a nice convenient property of Gaussians and the covariance matrices. In these papers, a single bundle adjustment (BA) iteration is performed in a manner similar to what I initially described in the question.

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} .

For an overview, see, e.g., Fletcher [20]. Each iteration has the following general structure: given the current iterate x, the next iterate is deﬁned by x¯ = x+αp, (1.2) where the vector p is the search direction, and the nonnegative scalar α is the steplength. The Schur complement plays an important role in matrix analysis, statistics, numerical analysis, and many other areas of mathematics and its applications. This book describes the Schur complement as a rich and basic tool in mathematical research and applications and discusses many significant results that illustrate its power and fertility.

Spectral analysis of coupled PDEs and of their Schur complements via Generalized Locally On element-by-element Schur complement approximations. Abstract. We consider element-by-element Schur complement approximations for indefinite and general nonsymmetric matrices of two-by-two block form, Symmetric and positive definite information matrix is presented in a block diagonal form in this paper using transformation, which involves the Schur complement.
