is not positive definite but is positive semidefinite. Find a factorization B = LDLT, where L is lower triangular with ones on the diagonal and D is a diagonal matrix with nonnegative diagonal elements. If such a factorization exists for every symmetric positive semidefinite matrix, explain why. If not, give a counterexample.
