SUMMARY Schur complement matrices S = D - CA-1B appeared early in the history of matrices in the work of Sylvester. With the rise into consciousness of generalized inverses in the 1960s and 1970s, various results for the classical Schur complement were extended to the formula S = D - CaB, where a is a generalized inverse of A. The Schur-complement method is a primal-feasible active-set method.
