For complex Hermitian matrix A, the following formula applies: Again, the pattern of access allows the entire computation to be performed in-place if desired. When used on indefinite matrices, the LDL* factorization is known to be unstable without careful pivoting;[10] specifically, the elements of the factorization can grow arbitrarily.
