On the Interoperability between Interval Software
Abstract
The increased appreciation of interval analysis as a powerful tool for controlling round-off errors and modelling
with uncertain data leads to a growing number of diverse interval software. Beside in some other aspects,
the available interval software differs with respect to the environment in which it operates and the provided
functionality. Some specific software tools are built on the top of other more general interval software but
there is no single environment supporting all (or most) of the available interval methods. On another side,
most recent interval applications require a combination of diverse methods. It is difficult for the end-users
to combine and manage the diversity of interval software tools, packages, and research codes, even the latter
being accessible. Two recent initiatives: [1], directed toward developing of a comprehensive full-featured library
of validated routines, and [3] intending to provide a general service framework for validated computing in
heterogeneous environment, reflect the realized necessity for an integration of the available methods and
software tools.
It is commonly understood that quality comprehensive libraries are not compiled by a single person or small
group of people over a short time [1]. Therefore, in this work we present an alternative approach based on
interval software interoperability.
While the simplest form of interoperability is the exchange of data files, we will focus on the ability to run
a particular routine executable in one environment from within another software environment, and vice-versa,
via communication protocols. We discuss the motivation, advantages and some problems that may appear in
providing interoperability between the existing interval software.
Since the general-purpose environments for scientific/technical computing like Matlab, Mathematica, Maple, etc.
have several features not attributable to the compiled languages from one side and on another side most problem
solving tools are developed in some compiled language for efficiency reasons, it is interesting to study
the possibilities for interoperability between these two kinds of interval supporting environments.
More specifically, we base our presentation on the interoperability between Mathematica [5] and external
C-XSC programs [2] via MathLink communication protocol [4]. First, we discuss the portability and reliability
of interval arithmetic in Mathematica. Then, we present MathLink technology for building external
MathLink-compatible programs. On the example of a C-XSC function for solving parametric linear systems,
called from within a Mathematica session, we demonstrate some advantages of interval software interoperability.
Namely, expanded functionality for both environments, exchanging data without using intermediate files and
without any conversion but under dynamics and interactivity in the communication, symbolic manipulation interfaces
for the compiled language software that often make access to the external functionality from within Mathematica
more convenient even than from its own native environment. Once established, MathLink connection to external
interval libraries or problem-solving software opens up an array on new possibilities for the latter.
