cse.sc.eduupdate to Cholesky factorization. Sf k = cholupdate Sf k, (x f,0 k −x f k), sgn{W 0} √ W0 (29) where sgn is the sign function and cholupdate returns the Cholesky factor of Sf k (S f k) T +W0 xf,0 k −x f k xf,0 k −x f k T Therefore the forecast covariance matrix can be written Pf k = S f k (S f k) T. The same way the posterior co ...

Cholesky decomposition
www.ucg.ac.meCholesky decomposition In linear algebra, the Cholesky decomposition or Cholesky factorization is a decomposition of a Hermitian, positive-definite matrix into the product of a lower triangular matrix and its conjugate transpose, which is useful for efficient numerical solutions, e.g. Monte Carlo simulations.
