In mathematics, a block matrix or a partitioned matrix is a matrix that is interpreted as having been broken into sections called blocks or submatrices. Intuitively, a matrix interpreted as a block matrix can be visualized as the original matrix with a collection of horizontal and vertical lines, which break it up, or partition it, … See more The matrix can be partitioned into four 2×2 blocks The partitioned matrix can then be written as See more If a matrix is partitioned into four blocks, it can be inverted blockwise as follows: where A and D are square blocks of arbitrary size, and B and C are conformable with them for partitioning. Furthermore, A and the Schur … See more A block diagonal matrix is a block matrix that is a square matrix such that the main-diagonal blocks are square matrices and all off-diagonal blocks are zero matrices. That is, a block … See more A block Toeplitz matrix is another special block matrix, which contains blocks that are repeated down the diagonals of the matrix, as a See more It is possible to use a block partitioned matrix product that involves only algebra on submatrices of the factors. The partitioning of the factors is not arbitrary, however, and requires "conformable partitions" between two matrices $${\displaystyle A}$$ See more The formula for the determinant of a $${\displaystyle 2\times 2}$$-matrix above continues to hold, under appropriate further assumptions, for a matrix composed of four submatrices $${\displaystyle A,B,C,D}$$. The easiest such formula, which … See more A block tridiagonal matrix is another special block matrix, which is just like the block diagonal matrix a square matrix, having square matrices (blocks) in the lower diagonal, See more
