The Cholesky decomposition of a Hermitian positive-definite matrix A is a decomposition of the form. where L is a lower triangular matrix with real and positive diagonal entries, and L * denotes the conjugate transpose of L.hen A has real entries, L has real entries as well and the factorization may be written A = LLT. The Cholesky decomposition is unique when A is positive definite; there is only one lower triangular matrix L with strictly positive diagonal entries such that A = LL *.
