Subject: Freely Available Linear Algebra Software Survey

I'm planning to update the survey of freely available software for the
solution of linear algebra problems. The July 2001 version of the survey
can be found at:
http://www.netlib.org/utk/people/JackDongarra/la-sw.html
The aim is to put in "one place" the source code that is freely
available for solving problems in numerical linear algebra, specifically
dense, sparse direct and iterative systems and sparse iterative
post a note on the na-digest when the new list is available.
Thanks,
Jack

Subject: TOMLAB PENSDP and PENBMI released

We are pleased to announce the release of two solvers for Semidefinite
Programming, TOMLAB /PENSDP and TOMLAB /PENBMI.

TOMLAB /PENSDP solves feasibility and optimization problems with linear
matrix inequalities by generalized Augmented Lagrangian method. The
solver is particularly aimed for large-scale problems with sparse data
structure.

TOMLAB /PENBMI solves (locally) feasibility and optimization problems
with linear and bilinear matrix inequalities.

Both solvers are available with MATLAB interface and several input
formats. They are integrated with the Tomlab graphical user interface
and the Tomlab driver routines. They may also be used as subproblem
solvers in the Tomlab environment.

The solvers have been developed in cooperation with PENOPT GbR. More
details can be found on http://tomlab.biz and http://www.penopt.com .

Subject: Second Derivative Approximation via Discrete Cosine Transform

Hello.

I would like to approximate the second derivative of a function using
discrete cosine transforms. This will be specially suitable for solving
with spectral methods PDE systems with Neumann conditions.

The following MATLAB code makes the approximation (in dimension 1) of
the second derivative of f(x) = cos(3*x) + cos(5*x). This function is
a sum of cosines and would have to be approximated perfectly using the
cosine basis (dct). However, in the left and right margins appears the
Gibbs phenomenon, that wouldn't have to occur because both the function
and its derivative are periodic and smooth in that points.=20

N = 256; % Number of points of the grid
xmax = pi;
x = -xmax:2*xmax/(N-1):xmax;
M = 0.5*[0:(N/2-1) (-N/2:-1)]; % Definition of the
k = pi*M/xmax; % wave numbers
f = cos(3*x) + cos(5*x); % function f(x)
h = -9*cos(3*x) - 25*cos(5*x); % exact second derivative
f_dct = dct(f);
h_dct = -k.^2.*f_dct;
h_approx = idct(h_dct); % approximate second derivative
plot(x,h); hold on; plot(x,h_approx,'r'); hold off

Does anybody know why is present the Gibbs effect? I don't know if I'm
doing something wrong or if it is a problem of the MATLAB routines dct
(discrete cosine transform) and idct (inverse discrete cosine transform).

Thank you.

Subject: New Book on Numerical Optimization

Numerical Optimization: Theoretical and Practical Aspects,
by J.F. Bonnans, J.Ch. Gilbert, C. Lemarechal, and C. Sagastizabal.
Springer-Verlag, Heidelberg, 2003 XIV, S. 423 Softcover

http://www.springer.de/cgi/svcat/search_book.pl?isbn=3-540-00191-3

Numerical Optimization has numerous applications in engineering sciences,
operations research, economics, finance, etc. Starting with illustrations
of this ubiquitous character, this book is essentially devoted to
numerical algorithms for optimization, which are exposed in a tutorial
way. It covers fundamental algorithms as well as more specialized and
advanced topics for unconstrained and constrained problems. The theoretical
bases of the subject, such as optimality conditions, Lagrange multipliers
or duality, although recalled, are assumed known. Most of the algorithms

described in the book are explained in a detailed manner, allowing
straightforward implementation. This level of detail is intended to
familiarize the reader with some of the crucial questions of numerical
optimization: how algorithms operate, why they converge, difficulties that
may be encountered and their possible remedies. Theoretical aspects of the
approaches chosen are also addressed with care, often using minimal
assumptions.

Subject: SISC Special Issue on Uncertainty Quantification

SISC Special Issue on Uncertainty Quantification

The SIAM Journal on Scientific Computing (SISC) has a call for
papers for a special volume of devoted to Uncertainty Quantification.
The papers in the special issue are sought to identify better approaches
to quantify the limitations and uncertainty in mathematical predictions
given known limitations on the physical fidelity of the model. Areas
ranging from scientific discovery to government policy increasingly
rely on large-scale simulations for scientific input to support high-impact
decisions. Global climate change, manufacturing,, and environmental
remediation are examples in which sufficient information about
integrated system behavior will not be available from full-system tests.
For predictive science, utilizing large-scale simulations, to be a credible
strategy to support decisions when the cost of making a mistake is
high, it is essential to have rigorous mathematical methods and
algorithms for assigning levels of accuracy, limits of applicability,
and degrees of confidence to the simulation results. Achieving these
goals will require new methodologies to identify, characterize,
and quantify the uncertainties.

The SIAM Journal on Scientific Computing is a premiere journal for
research articles on numerical methods and techniques for scientific
computation. Papers address computational issues relevant to the solution
of scientific or engineering problems and generally include computational
results demonstrating the effectiveness of the proposed techniques.
This series is one of SIAMs most cited journals and the articles in the
special issue will receive an excellent audience.

The Special Issue Editors (Steve Wojtkiewicz and Roger Ghanem) and will
work closely with the SI associate editors and you through the referee and
publishing process so that the highest-quality volume will emerge with the
fewest delays. The deadline for submission is April 30, 2003; this will
facilitate the special issue going to press as soon as possible.

All those interested should submit their papers either electronically or send
five hard copies of their manuscripts to the SIAM office, following SIAM's

http://www.siam.org/esubs/esisc.htm for details on electronic submission or
http://www.siam.org/journals/instruct.htm for details on hard copy submission.

Whether electronic or hard copy, the author(s) MUST clearly indicate in either
the electronic submission form or in the cover letter that the paper is being
submitted to the SISC Special Issue on Uncertainty Quantification. Papers
submitted after the April 30 deadline may not be considered for the special
issue, at the discretion of the SI Editors-in-Chief Roger Ghanem and Steve
Wojtkiewicz. The papers will be fully refereed by the special issue editorial
board for technical content and appropriateness for publication in SISC.

Subject: Special Issue on Matrix Computations and Statistics

Special Issue of Computational Statistics and Data Analysis
Matrix Computations and Statistics II

A number of interesting and important ideas have resulted from the relationship
between matrix computations and statistics. Well known examples include the
solution of least squares problems, computation of the singular value
decomposition and its generalizations, estimation of principal components,
computation of canonical correlations, several cluster analysis algorithms,
and the solution of total least squares problems.

A previous special issue on this area featured papers on multidimensional
scaling, an application to web search engines, an algorithm for seemingly
unrelated regression models, an error measurement model for motion analysis,
and a survey on alternating least squares problems. These papers left the
impression that the overlap between matrix computations and statistics is a
fertile area of research.

Thus we propose a second special issue on matrix computations and statistics.
The editors would like to receive papers on any of the topics listed above
and also topics such as latent semantic indexing, structured total least
squares, cluster analysis, complete orthogonal decompositions, data
compression, linear discriminant analysis, dimension reduction/feature
extraction, and applications of statistical matrix computing to other
scientific disciplines.

I would like to ask those researchers, who are interested to contribute
to a mini-symposium on Effective modeling of local fields in the VI-th
World Congress on Computational Mechanics, Beijing, China, September
5-10, 2004 to send me the title of the paper not later than March 20,
2003. The deadline for submission of abstracts is October 1, 2003.
Problems like composite laminates, inclusions, global-local and multi-
scale modeling, etc. solved by the technique, which reduces the solution
are aimed for presentation. E.g. the analytic approach combined with
a numeric one can reduce the discrete model even several hundred times
to achieve comparable accuracy of the solution. Also the error
estimates and other novel techniques which improve the efficiency of
the solution for the field of problems are welcome.
