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. WebApr 12, 2024 · Continue stitching on the marked line to the opposite corner of the corner block. Stitch back and forth on all the marked lines to finish off the corner. Quilt along the edge of the block to the next corner and repeat steps 8-10 until the block is done. When quilting, remember to stop at the edge of the quilt block.

WebJan 1, 1999 · Large, sparse, unsymmetric systems of linear equations appear frequently in areas such as chemical engineering. One way of speeding up the solution of these linear systems is to solve them in parallel by reordering the unsymmetric matrix into a bordered block-diagonal (BBD) form. A multilevel ordering algorithm is presented in this paper.
