A block matrix is a matrix that is partitioned into smaller matrices, known as "blocks." These smaller matrices can be of different sizes and can be arranged in a rectangular grid format. Block matrices are particularly useful in various mathematical fields, including linear algebra, numerical analysis, and optimization, as they allow for simpler manipulation and operations on large matrices. \#\#\# Structure of Block Matrices A matrix \\( A \\) can be represented as a block matrix if it is partitioned into submatrices.
