WebbThe next lemma shows that the Schur-complement matrices of symmetric positive-definite matrices are themselves symmetric and positive-definite. This result was used in Theorem 28.8, and its corollary is needed to prove the correctness of LU decomposition for symmetric positive-definite matrices.
