Skew Box Enclosure for the Parametric AE Solution Set
In this talk we present a outer estimate of the parametric AE
solution set by right-preconditioning of the parametric matrix.
The obtained outer estimate is in the form of a parallepiped,
called skew box. A right-preconditioning version of the
parametric Bauer-Skeel method for outer estimation of the
parametric AE solution set will be presented. In the special case
of parametric united solution set a right-preconditioning version
of the parametric fixed-point iteration will be outlined. The
properties and the usefulness of the new outer estimation will be discussed on a number of numerical examples.
