General Info

involving rational dependenciesHere you can solve parametric linear systems (square, over, or underdetermined) that involve rational dependencies between interval parameters. (This page is updated March 2006.) The solution method is a generalized parametric fixedpoint iteration combined with algebraic simplification and generalised interval arithmetic for obtaining sharp range enclosure. Input data (the system matrix, the righthand side vector, the parameters and the intervals wherein they vary) should be symbolicnumeric and must be specified in Mathematica notations.
