Summary: We provide a general finite iterative approach for constructing factorizations of a matrix \(A\) under a common framework of a general decomposition \(A=BC\) based on the generalized Schur complement. The approach applies a zeroing process using two index sets.

We consider element-by-element Schur complement approximations for indefinite and general nonsymmetric matrices of two-by-two block form, as arising in finite element discretized systems of PDEs The paper provides some analysis of the so-obtained approximation and attempts to quantify the quality of the underlying two-by-two matrix splitting in a way ...
