WebExample 3 — The Structure of D. D is a block diagonal matrix with 1-by-1 blocks and 2-by-2 blocks. That makes it a special case of a tridiagonal matrix. When the input matrix is positive definite, D is almost always diagonal (depending on how definite the matrix is). When the matrix is indefinite however, D may be diagonal or it may express the block … Web, the total number of blocks on the diagonal, and bN = n, the total matrix dimension. Thus, due to ﬁll-in, the cost of factoring the permuted matrix is almost three times the cost of factoring the block tridiagonal matrix.
