Subject: Matrices with Orthonormal Columns

I do not know whether I was the first to use the expression
"orthonormal matrix" for a matrix with orthonormal rows or columns,
but I do remember coining it for my own papers. Dirk Laurie (see
below) proposes replacing this term with "left-orthogonal" and
"right-orthogonal". I think this is undesirable for the following

1. The term "orthogonal" changes to "unitary" when the matrix
becomes complex; and one would expect it to also change in
the proposed extension. On the other hand, "orthonormal" works
for both cases.

2. In my experience, most of the time you know the dimensions of the
matrix in question and therefore do not need to qualify the term
"orthonormal." But you always have to qualify the proposed
extension of "orthogonal", since by itself orthogonal implies that
the matrix is square.

3. Even where qualifiers are necessary, I find "left" and "right" too
indirect. Since it is the rows or columns of the matrix that are
orthonormal, I would prefer "row-'' or "column-orthonormal matrix."
Better yet, since the need for qualifiers is infrequent, just write
it out: "a matrix with orthonormal rows." Incidentally, this usage
squares with the way we treat the term "full rank". A matrix of
known dimensions is simply of "full rank." If its dimensions are
not known it is of "full row rank" or "full column rank," whichever
is appropriate.

In NA Digest two weeks ago Dirk Laurie <> wrote:

There is as yet no generally accepted term for a (rectangular) matrix
with orthonormal columns. Some authors use "orthonormal matrix" but
that should have been the term for an orthogonal matrix.

I propose that we call it a "left-orthogonal" matrix, and a matrix with
orthonormal rows a "right-orthogonal" matrix.


Q is orthogonal if and only if Q' is the inverse of Q: Q'Q = QQ' = I.
Q is left-orthogonal if and only if Q' is a left-inverse of Q: Q'Q = I.
Q is right-orthogonal if and only if Q' is a right-inverse of Q: QQ' = I.

Subject: New Book, Schwarz-Christoffel Mapping

We are pleased to announce the appearance of our book
"Schwarz-Christoffel Mapping" from Cambridge University Press
Schwarz and Christoffel invented their formula for conformal mapping
of polygons around 1868, but it took about a century for computers to
enable the application of the formula to any but the simplest examples.
Applications can be found in surprisingly diverse fields, such as
electrical engineering, fluid dynamics, queuing theory, and numerical
linear algebra. This book contains many computed figures and an appendix
with examples of how to use the SC Toolbox for MATLAB
( It is the best (OK, only) book
devoted to Schwarz-Christoffel mapping to emerge in 70 years!

Subject: Workshop in Coimbra on Molecular Geometry Optimization

The Centro Internacional de Matem=E1tica (
and the Centro de F=EDsica Computacional ( are
organizing a workshop on Molecular Geometry Optimization. It will take
place in Coimbra, at the Physics Department of the University, between
July 1 and July 3, 2002.

This workshop is intended to bring together mathematicians, chemists and
physicists who work in molecular geometry optimization. Its main goal
is, therefore, to allow the interchange of ideas between scientists with
very different backgrounds and to provide a basepoint for the
development of joint research projects. The use of high-performance
computing software and hardware for performing realistic calculations of
molecular structure will also be highlighted.

Subject: Special Issue of LAA on Order Reduction of Large-Scale Systems

Special Issue on Order Reduction of Large-Scale Systems

Order reduction is a common theme within the simulation of complex
physical processes. Such simulations often result in very large
systems. For example, large systems arise due to accuracy
requirements on the spatial discretization of fluids or structures,
in the context of lumped-circuit approximations of distributed
circuit elements, such as the interconnect or package of VLSI chips,
or in simulations of micro-electro-mechanical systems (MEMS), which
have both electrical and mechanical components. Dimension reduction is
generally required for purposes of expediency and/or storage
reduction. Applications include compressed representation, efficient
data analysis and feature extraction, real-time analysis, construction
of low-order control mechanisms, and many others. Various reduction
techniques have been devised, but many of these are described in terms
that are discipline-oriented or even application-specific even though
they share many common features and origins. This special issue is
devoted to exposing the similarities of these approaches, identifying
common features, addressing application-specific challenges, and
investigating how recent reduction methods for linear systems might
be applied to nonlinear problems.

LAA has previously published four special issues devoted to the field
of Linear Systems and Control: 1983 (vol. 50), 1989 (vols. 122-124),
1994 (vols. 203-204) and 2002 (to appear). The cross fertilization
between numerical linear algebra and linear system theory has been
very fruitful. Now, we feel it is time to broaden the scope of these
interactions. In the past decade there has been considerable activity
in the area of dimension reduction for linear dynamical control
systems. However, dimension reduction has a much broader range of
application and interpretation. The goals of this special issue are
to highlight leading approaches and remaining problems in model
reduction for linear system theory, emphasize connections to POD,
extend theory and methodology to nonlinear problems, address
application-specific techniques.

This special issue will be open to all papers with significant new
results in dimension reduction of large systems where either linear
algebraic methods play an important role or new tools and problems of
linear algebraic nature are presented. Survey papers that illustrate
common themes across disciplines and application areas, and especially
where Linear Algebra techniques play a central role are highly
encouraged. Papers must meet the publication standards of Linear
Algebra and Its Applications and will be refereed in the usual way.

Areas and topics of interest for this special issue include, but are not
limited to:

* Methods and Theory for

- Linear (time-invariant and time-varying) dynamical systems
- Descriptor (singular) systems
- Nonlinear dynamical systems
- Second-order systems
- Passive systems
- Infinite-dimensional systems (e.g., PDE based systems)

* Application-Specific Techniques for

- Conservative systems (e.g. Molecular Dynamics)
- Computational fluid dynamics
- Structural analysis (e.g., condensation or sub-structuring)
- Micro-electro-mechanical systems (MEMS)
- Image processing
- Chemical kinetics

* Low-Order Modeling

- Proper orthogonal decomposition (POD)
- Wavelet techniques in dimension reduction
- Reduced-order modeling of distributed circuit elements

* Low-Order Design

- Low-order filter design techniques
- Controller reduction techniques

The deadline for submission of papers is March 31, 2003, and
the special issue is expected to be published in 2004.
