Subject: MathJournal for the Tablet PC

I thought that NA Digest readers might like to know about MathJournal,
xThink corporation's newest contribution to math on the Tablet PC
(released on July 28, 2004).

With MathJournal, the user writes complex math expressions by hand and
generates numerical solutions, symbolic solutions, and plots. MathJournal
automatically recognizes the type of problem and offers the appropriate
types of solution. MathJournal can also store definitions of constants,
intervals, and functions. Our Web site ( has further details.

MathJournal is attracting scientists, engineers and students who dream of
having "an intelligent sheet of paper" on which to solve problems.

MathJournal also serves a growing set of educators who see MathJournal's
potential as a teaching tool. In part, MathJournal is a boon to education
because of its natural, pen-based form factor, based on handwritten math
expressions. And the Tablet PC itself addresses the need for collaboration,
flexibility, and portability in the classroom.

Yours truly,

Subject: New Sparse Matrices in the Univ. of Florida Sparse Matrix Collection

I've just added many new sparse matrices to the Univ. of Florida sparse
matrix collection, located at: .
They include circuit simulation matrices from Sandia National Laboratories
and other sources, a large collection of matrices from Nick Gould, Yifan Hu,
and Jennifer Scott, matrices from the Oberwolfach model reduction benchmark,
and other matrices. A complete list is at:
(the newer matrices are at the end of the list).

The matrices in the collection are in both MATLAB *.mat and
Harwell-Boeing / Rutherford-Boeing format. A
convenient web interface for MATLAB is available. For example:

>> Problem = UFget ('GHS_psdef/audikw_1')

grabs the (rather large) GHS_psdef/audikw_1 matrix from the web and loads it
directly into your MATLAB workspace. The UFget function caches its matrices,
so that subsequent downloads don't require a web download. (UFget has not
yet been tested in MATLAB Version 7.0, however).

New submissions are always welcome.

Subject: Final Call for AD2004 Post-Conference Special Collection

Final Call for Papers
AD2004 Post-Conference Special Collection

This is a final call for papers for the special AD2004 post-conference
collection. The program committee of the AD2004 conference on Automatic
Differentiation held in Chicago, July 19-23, 2004 invites papers related
to the field for inclusion in a special post-conference collection to be
published in Springer's Lecture Notes in Computational Science and
Engineering series. Manuscripts should be no more than 15 pages in
length and should be prepared following the instructions at (if your LaTeX system
is missing the footmisc package, you can find it here). It is
anticipated that final papers will be limited to 12 pages, not including
bibliographic references.

Papers must be submitted electronically by August 31, 2004.
Refer to for submission instructions.

Subject: Southern California Matrix Meeting

First Announcement
Southern California Matrix Meeting
Saturday, November 13, 2004
San Jose State University, San Jose, California

Everyone interested is invited. This will be an informal gathering to
encourage the interaction and collaboration of researchers on matrices,
including applications, computation and theory. "SoCal" meetings were
begun by Bob Thompson and Steve Pierce in the 1980's. Following their
tradition, there will be no registration fee and a complimentary dinner
for all participants and partners, but no financial support.

For details, check the website (

There will be time slots for 20 minute and 30 minute talks. If you wish to
speak, send an abstract before November 1, 2004, to Wasin So. And if you plan
to come but not give a talk, let Wasin know by November 5 so we will be
sure to have enough food.

Organizers: Jane Day ( and Wasin So (
