I’ve sometimes seen it written LBLᵀ, LDLᵀ, or just Bunch-Kaufman. I prefer the first and third over the second because I find it too confusing to refer to a non-diagonal matrix as D. WebCholesky and Bunch-Kaufman Decompositions Description. The "Cholesky" class is the class of Cholesky decompositions of positive-semidefinite, real dense matrices. The "BunchKaufman" class is the class of Bunch-Kaufman decompositions of symmetric, real matrices. The "pCholesky" and "pBunchKaufman" classes are their packed storage …

WebThe Bunch–Kaufman decomposition is a generalization of theCholesky decomposition. Bunch–Kaufman decomposition of matrix A can be written as PAP0 = PLDL0 P0 where P is apermutation matrixthat permutes the rows of A. L is the permuted lower-triangular matrix. With the permutation matrix P, PL is a lower-triangular matrix with unit diagonal. 1 Webanl.gov
