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.
The chamois (Rupicapra rupicapra) is a goat-antelope species native to mountains in Europe, including the European Alps, the Pyrenees, the Carpathians, the Tatra Mountains, the Balkans, parts of Turkey, the Caucasus, and the Apennines.he chamois is a mid-sized bovid. A fully grown chamois reaches a height of 70â80 cm (28â31 in) and measures 107â137 cm (42â54 in) (the tail is not generally visible except when defecating). Males, which weigh 30â60 kg (66â132 lb), are slightly larger than females, which weigh 25â45 kg (55â99 lb).
