Efectua una deducció dels algorismes coneguts i d'actualització de factoritzacions de Cholesky de matrius simàtriques definides positives, per addició o sostracció de matrius de rang u. A més se'n fa una anàlisi numèrica consistent en raonar les seves propietats, possibilitats d'aplicació, i comptatge d'operacions aritmètiques requerides.The well known algorithms of Cholesky factorization update of symmetric positive definite matrices, for the cases of addition or substraction of rank one matrices. are developed. Besides,a numerical analysis is made of their properties, the possible field of implementation, and account of the number of arithmetic oprations required.Postprint (published version
