involving rational dependencies

Here 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 fixed-point iteration combined with algebraic simplification and generalised interval arithmetic for obtaining sharp range enclosure.

Input data (the system matrix, the right-hand side vector, the parameters and the intervals wherein they vary) should be symbolic-numeric and must be specified in Mathematica notations.

Manual input

Enter a parametric matrix row by row enclosed in curly brackets:

{ {p1/p2, 1+p2^2}, {-2, 3p1-1} }

Enter the right-hand side vector:



Enter the interval values for the parameters by a list of rules:
Rules have the form parameter_name -> numeric interval.
