Subject: Leslie Fox

It is with very great sorrow that I make the following announcement:

Leslie Fox died last night, August 1, 1992 in the John Radcliffe Hospital
in Oxford. A funeral service will be held at the Old Marston Parish
Church, Oxford, on Thursday or Friday August 5 or 6.

His wife Clemency and his brother Roy have asked me to make this

David M. Young (University of Texas, Austin) and David P. Young

As of this morning (Monday, July 27) my na-net Key is dpyoung.

Subject: LINPACK in C

In response to the recent query about the availability of
LINPACK in C: Such a package is available at no charge
on a PC diskette from MICROTOOLS, P.O. Box 2745,
Santa Clara, CA 95055-2745, Phone: (408)296-3478. Ask for
Andy Chan. MICROTOOLS markets a Fortran to C conversion
processor and other software tools. The LINPACK in C is
offered as a demonstration of a conversion done with their
processor. Other companies that market conversion
processors may have similar offers.

Subject: Fortran-to-C Converter

Some readers of the NA Digest seem unaware that netlib offers source
for a Fortran-to-C converter, f2c. Thus one answer to the question
"Are C-versions of LINPACK or LAPACK available in public domain?"
is that you can get Fortran for LINPACK and LAPACK from netlib and
use f2c to get corresponding C.

For more on f2c, send the E-mail message
send index from f2c
to . (Updates to f2c appear first on and eventually propagate to , , and perhaps elsewhere.)

Subject: VAX Fortran to SQL Translator

Objective: Convert VAX Fortran programs to use Oracle databases.

SIAM (Society for Industrial and Applied Mathematics) is
looking for information on the availability of an
automated translator to convert VAX Fortran source code
to something which can make use of Oracle-compatible
embedded SQL, with minimal hand coding.

Any references or leads to such a product would be greatly
appreciated. Thank you very much.

Subject: MATLAB Primer, 2nd Edition

The Second Edition of the MATLAB Primer is now available.

The plain TeX source of the latest version of the Primer will always
be available via

---Anonymous ftp from as the file
primer.tex in the directory pub/matlab, and

---Listserv: Send an email message to
containing the single line: send matlab/primer.tex

It should soon be available from NetLib by sending an email message to containing the single line:
send primer.tex from matlab/teaching
However, I cannot assure you that this file will be the latest version.
It can also be obtained by sending a request to the author at the
address below.

The Matlab Primer is intended to help students---and others---learn to
use Matlab. Extensive experience has shown that the Primer, along
with the on-line help facility, usually suffice for the students to
use MATLAB in a classroom setting. It is not intended to replace the
complete MATLAB User's Guide which is assumed to be available for
review at certain locations as a source of more in-depth information.

The second edition retains the character of the first as described
above. The primary changes from the first edition are inclusion of
more informative examples of M-files and a much more complete section
on graphics.

While the Primer is based on version 3.5 of MATLAB, it is compatible
with version 4.0 with the fundamental differences noted. An edition
of the Primer based on version 4.0 is under development.

The most convenient method of distribution seems to be through a local
copy center where the student can purchase it spiral bound for about $3.

Subject: On-line Info. from NSF (STIS)

Below is some info. on STIS -- the on-line info. system from NSF
(The National Science Foundation -- U.S. government funding agency):

The NSF now has an electronic publishing system called STIS -- The Science and
Technology Information System. Anyone can use it to get fast, 24-hour data on
many NSF activities. It has been around for at least a year.

You may also subscribe to a mailing list that will send you weekly NSF
announcement updates as follows (replace my name with your own):

Subject: <empty/ignored>

subscribe STSSUM-L Anne C. Elster

STSFUL-L will send you the whole documents rather than summaries.


With STIS, you need only....personal computer and a modem or access to
Internet... You can electronically search keywords, topics or phrases, then
read and print out the materials you want. They cover science, mathematics,
engineering, and technology activities supported by NSF, with new materials
added weekly. STIS has online "help" screens, and up to 10 people can be on
the system at the same time.... THERE ARE NO CHARGES.


- NSF program announcements and "how-to" grants booklets
- grant lists and summaries
- press releases, feature stories, tipsheets for the media
- newsletter & periodicals (e.g. NSF Bulletin, NSF Directions)
- catalogs & directories (annual guide to programs, NSF tel. book)
- vacancy announcements, NSF organizational information
- news on international science & technology
- NSF Annual Report, National Science Board special reports


Bitnet : access by email

Internet: type "telnet" or "telnet"
At a login-prompt type "public".

From a UNIX host, type "rlogin -l public"

Modem: 1200, 2400 or 9600 baud. Even parity, 7 data bits, full
duplex, VT100 emulation. On "connect" press [enter] [.] [enter]
At "login: type "public"

Personal observations/comments:

The same info. can be retrieved via WAIS (Wide Area Information Service)
for those with access to such systems. WAIS has a nicer interface and more
features, but can be very slow.

All documents can be ftp-ed by loggin in as "anonymous" to

STIS prompts you for terminals such as "sunkbd3, vt100, etc", but from
my Sun X-term window "vt100nkp" seems to work best. (Problems with scrolling
when using the others.)

The "Documents" menu currently lists 302 documents including updated NSF
announcements and surveys.

Subject: Tutorial in Power System Optimization

Invitation to the SVOR/ASRO - Tutorial in Thun, October 1992:
SVOR/ASRO - Optimization in Planning and Operation of Electric
October 15-16, 1992, Hotel Seepark, Seestrasse 47, CH-3602 Thun, Switzerland

Organizers: Prof. Dr. Hans Glavitsch, Dr. Rainer Bacher, ETH Zuerich
Dr. Karl Frauendorfer, University Zuerich

Increasing requirements in power supply necessitate efficient control of
electric power systems. An emerging subject of importance is
optimization which is the challenging principal theme of the announced
tutorial. Modelling aspects of unit commitment and optimal power flow
will provide the introduction to power systems control and to its
associated problem statement. Due to the nature of the underlying
optimization problems recent developments in advanced and
well-established mathematical programming methodologies will be
presented, illustrating in which way dynamic, separable, continuous and
stochastic features might be exploited. In completing the various
methodologies a number of presentations will state experiences with
optimization packages currently used for unit commitment and optimal
power flow calculations. One of the interesting objectives of this
tutorial is the fruitful communication - to be expected - between
operations research experts, analysts of the application's side and
users in the power industry.

We should be very pleased if you accept to participate at the tutorial.

Looking forward to meeting you in Thun,

yours sincerely

Technical University of Denmark

The Danish Center for Parallel Computer Applications is organizing
a two-day workshop on numerical methods for parallel computers.

During the two days, there will be talks on the following subjects:

- numerical linear algebra
- domain decomposition methods
- parallel preconditioners

In particular, we want to emphasize the interplay between these
subjects when solving large-scale PDE problems on today's massively
parallel computers. There will also be time for discussions.

The talks are presented at the workshop:

"Solution of Large Sparse Least Squares Problems"
Aake Bjorck, Linkoping University, Sweden

"Domain Decomposition and Parallel Conmputing"
