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.
Chamoy is a condiment from Mexico that is typically served as a dip for fresh fruit. It is made with fruit or fruit jams (such as apricot, mango or plum) , chillies and lime juice.Make it easily at home with apricot jam, lime juice and chilli powder.n place of ume, the typical Mexican chamoy uses apricot, plum or mango as its fruit base. Like umeboshi, Mexican chamoy is prepared by first packing the fruit in either dry salt or a brine. Occasionally, this brine is acidulated with vinegar. This draws out the natural moisture of the fruit by osmosis.
