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 *.
A chagoma is an inflammatory nodule at the bite site of the reduviid bug which transmits Chagas disease, not to be confused with Romana's sign which is periorbital soft tissue and lymphoid swelling which occurs when the T. cruzi protozoan that causes Chagas disease enters through the conjunctiva.
