A block upper triangular matrix is a square matrix that is divided into smaller square matrices, or blocks, where all blocks below the main diagonal are zero matrices. This structure is particularly useful for simplifying computations in linear algebra, as it allows for efficient matrix operations and the application of block matrix algorithms.
