-Contributed by Aren Drud: If you just need the Cholesky decomposition then you can compute it in GAMS with a loop as shown below. It is an extension of Oyvind'​s program in which I increased the number of observations to ensure that the matrix was positive definite (10 observations gives a matrix that is very close to being singular). There are additional example discussing Cholesky decompositions and positive semidefinite matrices in the GAMS-L archive -- it is a popular area.+Contributed by Arne Drud (adrud@arki.dk)
