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.
Chaga is a slow-growing fungus of the white and yellow birch trees. It is found in colder climates in Russia, China, Canada, Northern Europe, and Northern United States.haga is a dark brown or blackish-colored hard growth on the birch tree, which has a grainy, corky textured yellow or rust-colored interior. It is a âwhite-rot fungusâ like reishi, miatake, and several other health-promoting medicinal mushrooms.
