Subject: Did Roundoff Cause Patriot Failure?

Article on page 1347 of the 13 March 92 issue of Science
``Fatal Error: How Patriot Overlooked a Scud''
The error in question was a roundoff error, or roundoff errors.
The description of what happened is not clear, to me.
I would be interested in more detail than is offered in the article.
I am hoping that someone out there might be able to offer a plausible
explanation.

Subject: Looking for LU Decomposition Software on the CM-2

I am doing research in quantum mechanical scattering of low energy atoms
off crystal surfaces. This involves solving large systems of Fredholm
integral equations of the 2nd kind, which I do using a Nystrom method
currently. The linear systems that are generated are quite dense and
complex valued. Currently I run calculations on the Cray Y-MP which are
up to order 6,000 . However, I need to run some now which will be closer
to order 10,000 . I have a fair amount of computer time on CM-2s, so
this is the platform I would like to use for these calculations, if possible.
Originally I designed my code to use the CMSSL software library that TMC
provides, however, I have not been having good experiences with it. For
this and other reasons (having to do with some iterative methods I am
interested in trying), I would prefer to do a LU decomposition of my
matrix. If anyone has access to software to do a LU decomposition of
a complex matrix on the CM, I would very much appreciate hearing from you.

Subject: Mailing list for Auckland conference

Within the next week or two, a package announcing details of the

"International Conference on Scientific
Computation and Differential Equations"
Auckland, New Zealand, 4 - 8 January 1993

will be sent to all members of a mailing list that
has been put together from miscellaneous sources.

The package will contain
(1) A colour poster for display, promoting the conference.
(2) Some copies of a brochure containing registration details,
a call for papers and other information.
(3) Some copies of the registration form for the meeting.

Although we have made reasonable efforts to make sure that
a copy of the package will go to most people likely to be
interested, there is no doubt that there are many gaps in
our list. Please let me (butcher@mat.aukuni.ac.nz or
na.butcher@na-net.ornl.gov) or Horst Gerlach (gerlach@mat.aukuni.ac.nz)
know as soon as possible if you suspect that we do not have your
institution on our mailing list and you would like to receive the
package on the conference. In this case please give us the
name and Air Mail address of a suitable contact person.

Many thanks, John Butcher

Subject: Multidimensional Convolution

I have a two dimensional diffusion problem that will involve numerical
convolution. All the convolution algorithms, mostly based on FFT, that I
can find in archives, IMSL, BCS, etc., are for one dimensional vector
convolution that compute

$$ z_j = \sum_{k=1}^n x_{j-k+1} y_k $$

However, I need a similar program that can compute a two dimensional equivalent

$$ z_{j,m} = \sum_{k=1}^n \sum_{q=1}^n x_{j-k+1,m-q+1} y_{k,q} $$

but cannot find such a thing. Has anyone ever seen such a thing on netlib,
lapack, imsl, simtel, etc. ?? Thanks for any information.

Subject: Lancelot: A Nonlinear Optimization Package

ANNOUNCEMENT OF LANCELOT RELEASE A

We are pleased to announce the release of LANCELOT, a software package
for solving nonlinear optimization problems. The package is
particularly appropriate for large examples. The embedded algorithms
are designed to provide convergence to a local minimizer from any
starting guess. The package is suitable for both unconstrained and
constrained problems.

General features include facilities to compute numerical and check
analytical derivatives, and to restart interrupted computations
automatically. A variety of direct and iterative techniques are
provided to solve the necessary linear algebraic subproblems. The
software also uses a full reverse communication interface for greater
flexibility and adaptability.

The package is written in standard ANSI Fortran77. It has been ported
to CRAY supercomputers, Digital VAX minis, Digital DEC workstations,
IBM VM/CMS mainframes, and IBM RISC System/6000 and SUN workstations.
A fully automated installation procedure is supported for all these
machines/systems. Single and double precision versions are available.
The program's dimensions may also be adapted to fit within machines
with different memory sizes.

Further information on the package is available from Philippe Toint at
pht@math.fundp.ac.be

NEW PUBLICATION FROM SIAM

Ten Lectures on Wavelets
Ingrid Daubechies
CBMS-NSF Regional Conference Series in Applied Mathematics 61

Wavelets are a mathematical development that may revolutionize
the world of information storage and retrieval according to many
experts. They are a fairly simple mathematical tool now being
applied to the compression of data--such as fingerprints, weather
satellite photographs, and medical x-rays--that were previously
thought to be impossible to condense without losing crucial
details.

Contents
Introduction; Preliminaries and Notation; The What, Why, and How
of Wavelets; The Continuous Wavelet Transform; Discrete Wavelet
Transforms: Frames; Time-Frequency Density and Orthonormal Bases;
Orthonormal Bases of Wavelets and Multiresolutional Analysis;

Subject: LAPACK Users' Guide Now Available

NOW AVAILABLE FROM SIAM ... TO BE PUBLISHED MAY 29, 1992

LAPACK Users' Guide
E. Anderson, Z. Bai, C. Bischof, J. Demmel, J. Dongarra, J. Du
Croz, A. Greenbaum, S. Hammarling, A. McKenney, S. Ostrouchov,
and D. Sorensen

LAPACK is a transportable library of Fortran 77 subroutines for
solving the most common problems in numerical linear algebra.
LAPACK supersedes LINPACK and EISPACK, principally by
restructuring the software to achieve much greater efficiency on
vector processors, high-performance "superscalar" workstations,
and shared memory multiprocessors. LAPACK also provides extra
functionality, uses some new or improved algorithms, and
integrates the two sets of algorithms into a unified package.

LAPACK Users' Guide gives an informal introduction to the design
of the algorithms and software, summarizes the contents of the
package, and describes conventions used in the software and its
documentation.

LAPACK can be used to solve the most common problems in numerical
linear algebra: systems of linear equations; linear least
squares problems; eigenvalue problems; singular value problems;
matrix factorizations; estimating condition numbers

Additional improvements over LINPACK and EISPACK include: faster
run time; better error bounds; more and better condition numbers

Special features of the guide include: Quick reference guide to
the BLAS; How to convert calls to LINPACK or EISPACK to LAPACK;
Quick reference tables for Driver Routines

The authors have directed that royalty from the sale of this book
be placed in a fund administered by SIAM to help students attend
SIAM meetings and other related SIAM activities.

All purchasers of LAPACK Users' Guide will be notified of
software updates.

Subject: Bibliography of Soviet Works on Interval Computations

BIBLIOGRAPHY OF SOVIET WORKS ON INTERVAL COMPUTATIONS


To date authors from the former Soviet Union have published or prepared
for publication at least 500 papers in Russian devoted to various areas
of Interval Computations. Unfortunately, due to the language barrier
and problems with access, these works are practically unknown outside
the former Soviet Union. This publication is a step to remedy this
situation. The bibliography includes references to the works of
authors who were citizens of the Soviet Union when the works were
written.

The list, prepared in the Computer Center of the Siberian Branch of the
Russian Academy of Sciences (Krasnoyarsk) under the management of Dr.
Boris S.Dobronets, was taken as the basis for the bibliography. Later,
the list was corrected, appended and translated into English by Lyudmila
V.Kupriyanova (Saratov State University), and edited by Alexander
G.Yakovlev (Moscow, Institute for New Technologies) and R.Baker Kearfott
(University of Southwestern Louisiana).

The Editorial Board of the International Journal "Interval Computations"
can offer translation upon demand of these papers into English.

We can also supply foreign readers with copies of these materials in
Russian. To order copies, please contact the above representative in
this case, too.
