WebBunch-Kaufman Decomposition Methods Description. The Bunch-Kaufman Decomposition of a square symmetric matrix A is A = P LDL' P' where P is a permutation matrix, L is unit-lower triangular and D is block-diagonal with blocks of dimension 1\times 1 or 2\times2. This is generalization of a pivoting LDL' Cholesky decomposition. Usage Web“People who should make us humble,” says company owner Abe Karem.
