Subject: LAPACK 3.2 released

LAPACK 3.2 was released on Nov 16, 2008.

Highlights of the latest release include the following:

Linear solvers that “guarantee” fully accurate answers
(or give a warning that the answer cannot be trusted)
XBLAS, or portable extra-precise BLAS, used by above linear solvers
QR decomposition that can run in O(n^2) time on "narrow profile"
matrices stored in dense format (including but not limited
to band matrices)
QR decomposition that guarantees non-negative real diagonal of R
High accuracy Jacobi-based SVD (more accurate for tiny singular
values, and faster than QR-based SVD on average)
New packed storage for symmetric, Hermitian and triangular matrices
that runs at full BLAS3 speed
Pivoted Cholesky for semi-definite symmetric matrices
Mixed precision iterative refinement that solves double-precision
problems at single-precision speeds
Right-looking, left-looking and recursive variants of LU, QR
and Cholesky, which can run faster depending on architecture
Various improvements to DQDS algorithm for bidiagonal SVD, and
to multishift Hessenberg QR algorithm

Subject: NSF Mathematical and Statistical Research for Threat Detection

Dear Colleague Letter for the Division of Mathematical Sciences
with the title "Mathematical and Statistical Research for Threat

Dear Colleague:

The Division of Mathematical Sciences (DMS) at the National Science
Foundation (NSF) has a long history of supporting scientific
research to develop technology in order to secure the national
defense. We expect, beginning in FY 2009, to form a partnership
with the Defense Threat Reduction Agency (DTRA) to develop the next
generation of mathematical and statistical algorithms and
methodologies in sensor systems for the detection of chemical and
biological materials as an area of emphasis within the
Computational Mathematics program. These new algorithms could be
formed, but are not limited to, mathematical research areas such as
mathematical modeling, signal processing, statistics, harmonic and
geometric analysis, topology, numerical analysis, and optimal

The purpose of this letter is to make the mathematical sciences
community aware of this upcoming opportunity in order to begin to
formulate thoughts and collaborations, and to assemble a diverse
group of mathematical sciences researchers who are actively working
in the above described research areas to create innovative and
novel algorithms and methodologies.

DMS and DTRA recognize the needs and opportunities for the
mathematical sciences community to develop technology for
controlling and reducing the threat from biological and chemical
attack. We seek ambitious, transformative, and creative
research proposals from individual PIs and collaborative groups in
the mathematical sciences community. Proposals should have in
the title ATD (Algorithms for Threat Detection) and should be
submitted to the Computational Mathematics program of DMS within
the submission window from December 1 to December 15.

Please see for
additional information.

Subject: New book, Differential-Algebraic Systems

A new book on differential-algebraic equations (DAEs) has been recently
released. Entitled "Differential-Algebraic Systems: Analytical Aspects and
Circuit Applications", it is authored by Ricardo Riaza, from Universidad
Politécnica de Madrid, Spain, and published by World Scientific. The scope of
the book is summarized below.

DAE theory provides an essential tool for system modeling and analysis within
different fields of applied sciences and engineering. This book addresses
modeling issues and analytical properties of DAEs, together with some
applications in electrical circuit theory. Beginning with elementary aspects,
the book provides a self-contained and comprehensive presentation of several
advanced topics in DAE theory, such as the full characterization of linear
time-varying equations via projector methods or the geometric reduction of
nonlinear systems. Recent results on singularities are extensively discussed.
The book also addresses in detail differential-algebraic models of electrical
and electronic circuits, including index characterizations and qualitative
aspects of circuit dynamics. In particular, the reader will find a thorough
discussion of the state/semistate dichotomy in circuit modeling. The state
formulation problem, which has attracted much attention in the engineering
literature, is tackled here as a reduction problem on semistate models.

The book can be used in a graduate course on DAEs. Applied mathematicians and
analysts, as well as electrical and electronic engineers, may also benefit
from its contents.

Subject: New book, Applied Calculus of Variations for Engineers

Louis Komzsik, Applied Calculus of Variations for Engineers
Taylor & Francis, 2008

The subject of calculus of variations is to find optimal solutions to
engineering problems where the optimum may be a certain quantity, a shape, or
a function. Applied Calculus of Variations for Engineers addresses this very
important mathematical area applicable to many engineering disciplines. Its
unique, application-oriented approach sets it apart from the theoretical
treatises of most texts. It is aimed at enhancing the engineer's understanding
of the topic as well as aiding in the application of the concepts in a variety
of engineering disciplines.

The book is organized into two parts: theoretical foundation and engineering
applications. The first part starts with the fundamental variational problem
and its solution via the Euler-Lagrange equation. This is followed by extension
to variational problems subject to constraints, containing functions of multiple
variables and functionals with higher order derivatives. It continues with the
inverse problem of variational calculus, when the variational problem is sought
corresponding to a differential equation. The first part concludes with direct
solution techniques (the Ritz, Galerkin, and Kantorovich methods).

The second part starts with geometric applications, including the geodesic
concept of differential geometry and extensions to higher order spaces. The
computational geometry chapter covers the variational origin of natural splines
and formulation of B-splines under various constraints. The final two chapters
focus on analytic and computational mechanics. Topics include the variational
form and subsequent solution of several classical mechanical problems using
Hamilton's principle. The last chapter discusses generalized coordinates and
Lagrange's equations of motion. Fundamental applications of elasticity, heat
conduction, and fluid mechanics with computational technology conclude the book.

Subject: Course on Linear Matrix Inequalities, Prague, Feb 2009

Course on LMI optimization with applications in control
by Didier Henrion, LAAS-CNRS, Toulouse, France
and Czech Technical University in Prague, Czech Republic.

Venue and dates:
The course is given at the Czech Technical University in Prague,
Charles Square, down-town Prague (Karlovo Namesti 13, 12135 Praha 2)
from Monday February 2 to Friday February 6, 2009. It consists of
six two-hour lectures and two two-hour Matlab labs. There is no
admission fee, students and researchers from external institutions
are particularly welcome, but please send an e-mail to
<> to register.

This is a course for graduate students or researchers with some
background in linear algebra, convex optimization and linear control
systems. The focus in on semidefinite programming (SDP), or
optimization over linear matrix inequalities (LMIs), an extension of
linear programming to the cone of positive semidefinite matrices.

In the first part of the course, historical developments of LMIs and
SDP are surveyed. Convex sets that can be represented with LMIs are
classified and studied. LMI relaxations are introduced to solve
non-convex polynomial optimization problems, with a focus on the
theory of measures and moments. Finally, interior-point algorithms
are described to solve LMI problems and latest achievements in software
and solvers are reported. The second part of the course focuses on
the application of LMI techniques to solve control problems. Standard
control problems are revisited thanks to recent results on invariant
measures and SDP. Finally, more difficult control problems, such as
robustness analysis of linear systems, or design of fixed-order robust
controllers with H-infinity specifications, are addressed thanks
to the flexibility of the LMI framework. The originality of the approach
is in the simultaneous use of algebraic or polynomial techniques
(as opposed to classical state-space methods) and modern convex
optimization techniques. For the labs we use YALMIP, GloptiPoly,
SeDuMi and PENNON under a Matlab environment.
