Cholesky decomposition is numerically stable, and can be obtained without carrying the matrix to an upper triangular matrix form. To see this, now, for a 3 × 3 , positive definite matrix A = [ a ij ] write down U T U = A in component and find a formula(s) to calculate entries of the upper triangular matrix U .
