What Is a Block Matrix? – Nick Higham

WebA block matrix or a partitioned matrix is a matrix that is interpreted as having been broken into sections called blocks or submatrices. Partitoned matrices appear in most modern applications of linear algebra because the notation highlights essential structures of matrices. Partititoning a matrix is a generalization to used previously a list ... WebTo prove (1), it suffices to note that (A B 0 D) = (A 0 0 D)(I A − 1B 0 I) From here, it suffices to note that the second matrix is upper-triangular, and to compute the determinant of the first matrix. It is easy to see that the determinant of the first matrix should be det (A) det (D) if we use the Leibniz expansion. charity knappWebYou can generalize (1) to block matrices, i.e., the formula still works when every $A_{i,k}$ and $B_{k,j}$ is itself a matrix [and the subscripts enumerate rows and … charity king below deck
