The , and , Algorithms for Symmetric Matricesis unitary and . is upper-triangular then . that is, . is unitarily similar to . By repeated application of the above result a sequence of matrices which are unitarily similar to a given matrix .. may be derived from the relations . and, in general, .. tends to upper-triangular form.

Rational , Transformation with Newton Shift for Symmetric Tridiagonal Matricesroughout the iteration. Thus, the . step may be achieved by two successive Cholesky . steps or equivalently, since the matrix is tridiagonal, by two . steps which are numerically stable and avoid square roots. The rational . step used here needs slightly fewer additions than the Ortega-Kaiser step .

Iterative Refinement of the Solution of a Positive Definite System of Equations based on the Cholesky factorization of . is ill-conditioned the computed solution may not be sufficiently accurate, but (provided . is not almost singular to working accuracy) it may be improved by an iterative procedure in which the Cholesky decomposition is used repeatedly.
