Inner and Outer Bounds for the Solution Set of Parametric Linear Systems
Consider linear systems involving affine-linear dependencies on interval parameters. Presented is a free C-XSC software implementing a generalized parametric fixed-point iteration method for verified enclosure of the parametric solution set. Some specific features of the corresponding algorithm concerning sharp enclosure of the contracting matrix and inner approximation of the solution enclosur...
متن کاملOuter Bounds for the Parametric Controllable Solution Set with Linear Shape
We consider linear algebraic equations, where the elements of the matrix and of the right-hand side vector are linear functions of interval parameters, and their parametric AE-solution sets, which are defined by universal and existential quantifiers for the parameters. We present how some sufficient conditions for a parametric AE-solution set to have linear boundary can be exploited for obtaini...
متن کاملA Method for Outer Interval Solution of Linear Parametric Systems
The paper deals with the problem of determining an outer interval solution (interval enclosure of the solution set) of linear systems whose elements are affine functions of interval parameters. An iterative method for finding such a solution is suggested. A numerical example illustrating the new method is solved.
متن کاملEnclosures for the solution set of parametric interval linear systems
We investigate parametric interval linear systems of equations. The main result is a generalization of the Bauer–Skeel and the Hansen–Bliek–Rohn bounds for this case, comparing and refinement of both. We show that the latter bounds are not provable better, and that they are also sometimes too pessimistic. The presented form of both methods is suitable for combining them into one to get a more e...
متن کاملInner estimation of the parametric tolerable solution set
We consider a linear algebraic system A(p)x = b(q), where the elements of the matrix and the right-hand side vector are linear functions of uncertain parameters varying within given intervals. The linear tolerance problem for the so-called parametric tolerable solution set Σtol(A(p), b(q), [p], [q]) = {x ∈ Rn | (∀p ∈ [p])(∃q ∈ [q])(A(p)x = b(q))} requires an inner estimation of this solution se...
