WebMar 24, 2024 · A block diagonal matrix, also called a diagonal block matrix, is a square diagonal matrix in which the diagonal elements are square matrices of any size … WebMar 1, 1995 · A package of Fortran subroutines is presented for the least-squares solution of a system of overdetermined, full-rank, linear equations with single-bordered block-diagonal structure. This structure allows for a natural sequential processing, one block diagonal at a time, so that large systems can be handled even on smaller machines.
WebIn the paper, tearing is applied to hierarchically described systems, where each subsystem is itself composed of subsystems, and so on to arbitrary depth. This structure gives rise naturally to ‘recursive’ bordered block diagonal (BBD) matrices, where each diagonal block is itself in the BBD form.
WebThe objective of this paper is to present a recursive algorithm for permuting sparse matrices into the bordered block diagonal form. An outstanding feature of this algorithm is the resulting balance between the border size and the size of the diagonal blocks, which gives rise to an efficient multilevel scheme for parallel matrix factorization. This scheme is … WebJul 31, 2006 · Bordered block diagonal form is desirable because it can guide and speed up the solution process for linear and integer programming problems. We show …
