It is often useful to consider matrices whose entries are themselves matrices, called blocks. A matrix viewed in this way is said to be partitioned into blocks. For example, writing a matrix B B in the form. B= [b1 b2 … bk] where the bj are the columns of B B = [ b 1 b 2 … b k] where the b j are the ...
WebMar 24, 2024 · Block matrices can be created using ArrayFlatten . When two block matrices have the same shape and their diagonal blocks are square matrices, then they multiply … 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 … 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 diagonal matrix A has the form 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 Toeplitz matrix has elements repeated down the … 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 $${\displaystyle A,B,C,D}$$.
