Subject: NA Digest Obituaries: Death of Dense Linear Algebra Research?
In a recent message, Gene Golub encouraged postings to NA Digest that may be
controversial in nature, in an effort to make NA Digest less boring. I have
put together some thoughts on the health of Dense Linear Algebra as a field
of research. Since it is a bit verbose, I have put my comments on a
webpage: http://www.cs.utexas.edu/users/flame/LA_health.htm

Subject: Re: dull Digest, and linear algebra papers
Hello,
I think what Gene referred to 2 weeks ago is the lack
of professional communication that might be viewed as
evidence of a cohesive research community. To be sure,
some of us think that numerical analysis or computational
mathematics is such a community, but where does the
discourse of that community occur? There are no annual
conferences exclusively for numerical analysts. This
digest is probably inadequate, and peer reviewed papers
are inappropriate, as venues to develop shared goals and
a vision of the future.
Here is a something along those lines that I offer as
a topic for discussion. On my web pages I have put a
graph of linear algebra papers by year; I have further
classified the papers as either pure or numerical
according to their math subject classification (MSC).
http://seesar.lbl.gov/ccse/people/grcar/LinearAlgebra/linearAlgebra.pdf
By this data, the numerical linear algebra community
has shrunk by about 25 percent over the last few years!
Is the data flawed, or does it indicate a trend? If
a trend, is it peculiar to linear algebra, or is it
true for other areas of numerical analysis? I have
some thoughts, but I've said enough.
rsvp, -- Joe Grcar jfgrcar@lbl.gov

Subject: Graphical user interfaces for teaching elementary numerical analysis
I am developing GUIs for some of the basic problems of elementary
numerical analysis. One of the frustrations that I and others have faced
is how to get students in numerical analysis to do experimental computing.
Typically we assign Matlab programs, either to be used directly or to be
modified. The students work to make the programs perform properly; and
when they are successful, they want to stop. But it is at this point that
we want them to start doing experimental studies. In part because of this,
I have been developing GUIs to take away all of the programming effort,
allowing the students to experiment with a numerical method without
needing to know how to program. [Learning to use Matlab and to program in
it is still a part of the course, however.]
The GUIs have been developed using the Matlab program GUIDE (GUI
Development Environment). They are available from the following ftp site:
http://www.math.uiowa.edu/ftp/atkinson/ENA_Materials/GUI/
Two files are included on the use of the GUIs. You can download the
individual files, or you can use the single compressed file NA_GUIs.zip. I
am interested in knowing what others think of the idea of using such GUIs
in teaching elementary numerical analysis.
If you find errors in using any of these GUIs, please notify me, at the
email address
Kendall-Atkinson@uiowa.edu.
The Matlab coding in these programs can be improved a great deal (I admit
to be far from proficient at the programming needed to use GUIDE wisely);
but the GUIs do work on the Windows and Linux machines we are using. At
this point, I am more interested in exploring the idea of using these GUIs
and in deciding what should be included in each one.

Since the publication of "Spectral Methods in Fluid Dynamics", spectral
methods, particularly in their multidomain version, have become firmly
established as a mainstream tool for scientific and engineering
computation. The authors now incorporate the many improvements in the
algorithms and the theory of spectral methods that have been made since 1988.
The initial treatment "Fundamentals in Single Domains" discusses the
fundamentals of the approximation of solutions to ordinary and partial
differential equations on single domains by expansions in smooth, global
basis functions. The first half of the book provides the algorithmic
details of orthogonal expansions, transform methods, spectral
discretization of differential equations plus their boundary conditions,
and solution of the discretized equations by direct and iterative
methods. The second half furnishes a comprehensive discussion of the
mathematical theory of spectral methods on single domains, including
approximation theory, stability and convergence, and illustrative
applications of the theory to model boundary-value problems.
A companion book "Evolution to Complex Geometries and Applications to
Fluid Dynamic" will contain an extensive survey of the essential
algorithmic and theoretical aspects of spectral methods for complex
geometries and provides detailed discussions of spectral algorithms for
fluid dynamics in simple and complex geometries.

SUBMISSION DEADLINE: June 6, 2006
The 2006 Workshop "Combining Visualisation and Interaction to Facilitate
Scientific Exploration and Discovery" (British HCI - V&I 2006) aims to
promote the importance of HCI and usability aspects in the visualisation
and exploration of complex data and sharing obtained knowledge with other
people. We encourage researchers and practitioners from a wide range of
disciplines to participate in the discussion of the following topics:
- How can interactive visualisation methods and tools be augmented to
address concerns of both scientific computing and HCI?
- What are the criteria for choosing between advanced projection equipment
and input devices?
- How can visualisation and multi-modal interaction techniques be
integrated to ensure a good user experience?
- Which research questions need to be considered when aiming to achieve
efficient HCI and ‘human-to-human’ interaction between scientists while
exploring complex data spaces?
- In what way can users expectations and the environment of use be
modelled when designing interactive visualisation systems?
- How can we define effective abstractions for the visualisation and user
interaction processes?
- What is the impact of the task or application field on interactive
visualisation?
- To what extent are usability problems independent of the context of use
and need to be taken into account when designing interactive visualisation
environments?

A reformulation of a mathematical programming problem is loosely intended as a

interesting and/or useful to solve the problem and/or gain insights about
it. As such, "reformulation theory" is extremely interesting and also very
important from a practical point of view.
We would like to invite high-quality submissions for this issue. We will
welcome all contributions focusing on reformulations and/or relaxations based
on the mathematical programming formulation of any optimization problem form:
LP, NLP, IP, MIP, Multi-objective, ...

Subject: CFP, CSDA and Signal Processing on TLS and EIV Modeling
Scope: The total least squares (TLS) method is a numerical linear
algebra tool for solving approximately overdetermined systems of
equations Ax = b, where both the vector b as well as the matrix A are
assumed perturbed. Since its definition by Golub and Van Loan in 1980,
the classical TLS method has been extended to solve weighted,
structured, and regularized TLS problems and was applied in signal
processing, system identification, computer vision, document retrieval,
computer algebra, and other fields. Errors-in-variables (EIV) models,
also known as measurement error models, are an alternative to the
classical regression model in statistics when both the dependent as well
as the independent variables are subject to errors. Errors-in-variables
models are closely related to TLS methods and provide statistical
justification for the deterministic approximation criteria used in the
numerical linear algebra literature. In this special issue, we are
aiming at the synergy of statistics and computations that provides
better computational methods for statistically meaningful estimators, as
well as new applications of the TLS techniques and EIV models.
Relevant topics:
- Concepts and Properties : structured and weighted TLS, other norms,
misfit versus latency errors, Bayesian estimation, nonlinear measurement
error models, dynamic errors-in-variables, hypersurface fitting,
statistical, numerical, robustness and optimization aspects
- Algorithms : real-time, adaptive, recursive, neural, iterative
algorithms, based on SVD or related matrix/tensor decompositions,
architectures, complexity, accuracy, regularization, convergence, lower
rank approximations
- Applications : array signal and image processing, filtering, system
identification, computer vision, document retrieval, spectral analysis,
harmonic retrieval, direction finding, signal/image blind
deconvolution/deblurring, biomedicine
Submission deadline: October 1, 2006.
