Subject: Interactive Numerical Examples in ETNA

Many papers in computational mathematics contain numerical
examples that illustrate the theory discussed, or the virtues
or shortcomings of numerical methods. The examples, in general,
depend on certain parameters, whose values are chosen by the
author of the paper. A reader may be interested in studying
the examples for other parameter values, but typically this is
not straightforward. Computer programs may have to be written
or requested from the author of the paper.

The Electronic Transactions on Numerical Analysis (ETNA) makes
it possible to publish interactive examples that allow readers
to vary parameter values. Presently, two papers

J. Baglama, D. Calvetti and L. Reichel, Fast Leja points,
ETNA 7 (1998), pp. 124-140,

R. S. Varga and A. Krautstengl, On Gersgorin-type problems
and ovals of Cassini, ETNA 8 (1999), pp. 15-20,

illustrate this feature. Click on the ``interactive supplement''
for these papers for a demonstration.

Authors of papers accepted for publication in ETNA are encouraged
to supply interactive examples. The ETNA staff will assist with
the design and Java programming of the examples.

ETNA is available at

http://etna.mcs.kent.edu

and at mirror sites. In addition volumes 1-10 of ETNA are available
on a new CDROM. The ETNA CDROM contains papers published in ETNA
1993-2000, interactive examples, a search engine and web browsers.
A limited number of CDROMs are available for $10 each. Please send
e-mail to etna@mcs.kent.edu if you would like your own portable copy
of ETNA on a CDROM.
