Subject: LAPACK, version 2.0
ANNOUNCING
LAPACK, Version 2.0 and LAPACK Users' Guide, Second Edition
DATE: September 30, 1994
LAPACK is a library of numerical linear algebra subroutines designed for
high performance on workstations, vector computers, and shared memory
multiprocessors. Release 2.0 of LAPACK introduces new routines, as well
as extending the functionality of existing routines. The most significant
new routines and functions are:
1) the generalized nonsymmetric eigenproblem Ax = lambda Bx
2) the generalized definite banded eigenproblem Ax = lambda Bx
3) two generalized linear least squares problems (least squares with
linear constraints, and the Gauss-Markov linear model problem)
4) the generalized (quotient) singular value decomposition
5) faster routines for symmetric eigenproblems, based on divide-and-conquer
6) a faster bidiagonal SVD (singular values only)
7) reduction of a band matrix to bidiagonal form
8) improved linear system drivers, to better reuse existing factorizations,
and return the pivot growth factor
9) the least squares drivers now return the residual root-sum-of-squares
Numerous bug fixes, code modifications, and/or commenting changes have
also occurred. For a detailed listing of these modifications please refer
to the revisions.info file on netlib.
echo "send revisions.info from lapack" | mail netlib@ornl.gov
Please note that the structure of the lapack directory on netlib has
changed. The major difference is that the SRC files are no longer
contained in the top-level lapack directory but in its subdirectories
single, double, complex, and complex16. The indexes in the lapack
directory and its subdirectories now list each of the different precisions
of a subroutine individually. The latter change has been made to ease
the development of html search capabilities.
A C translation of the library is nearly complete and will be released soon.
The second edition of the LAPACK Users' Guide coincides with the release
of version 2.0 of LAPACK and should be available from SIAM in the next
couple of months. The major changes to the guide involve the
discussion of new routines that have been added since the first public
release, version 1.0, in February, 1992. Chapter 3, on performance, has
been updated to include performance results for version 2.0, as well as
extended to include an "LAPACK Benchmark" for selected driver routines.
Chapter 4, on accuracy and stability, has been simplified and rewritten.
The Bibliography and Index have been moved to the end of the book.
The Index has been expanded into two indexes: Index by Keyword and
Index by Routine Name. Occurrences of LAPACK, LINPACK, and EISPACK
routine names have been cited in the latter index.

Subject: Belgian `NA-net-like' digest
This is a pointer to inform you of the existence of the SCME mailing list and
the SCME digest. It may be of interest to people using or researching numerical
computing, who are not too far from Belgium, since it is basically of regional
interest.
What is SCME? SCME = SCIENTIFIC COMPUTING and MATHEMATICAL ENGINEERING
SCME is a _regional_ electronic mailing list intended to quickly spread
information related to scientific computing and mathematical engineering.
Regional means: of interest to anybody within two to three hours drive from the
centre of Belgium, which practically includes the Benelux and nearby areas in
France and Germany.
You can find more information on SCME in the SCME WWW page:
http://www.cs.kuleuven.ac.be/~scme/
or, if you have no WWW access, by sending an email to scme@cs.kuleuven.ac.be.
We hope to hear from you!

Subject: New Book, Polynomial and Matrix Computations
POLYNOMIAL AND MATRIX COMPUTATIONS
Volume 1: Fundamental Algorithms
D. Bini, Universita di Pisa & V.Y. Pan, Lehman College, CUNY
Matrix and polynomial computations are fundamental to the theory
and practice of computing. The authors present here a systematic
treatment of algorithms and complexity in these two related
areas. Their study of computations with Toeplitz matrices and
other dense structured matrices demonstrates the links between
matrix and polynomial computations, as well as between numerical
and algebraic approaches to computation, both of which are
extensively applied in the book.
The authors begin with classical fundamental problems and
gradually bring the reader to and beyond the frontiers of current
research. Most of the material has not yet appeared in book
form; many results from recent publications and several new
unpublished results are included. In particular, the book
provides improved parallel algorithms for computations with
structured matrices and their further applications to some
fundamental computations with matrices and polynomials. It
demonstrates some general techniques of the design of efficient
parallel algorithms for algebraic and numerical computations also
having applications to combinatorial and graph computations. In
addition, it presents new techniques for data compression.
The book is designed as a text for advanced graduate students in
mathematics and computer science. It is also intended as basic
reading for designers of algorithms and software and for research
workers in the areas of algebraic computing, numerical
computational mathematics and numerical analysis.

Subject: One day course on MATLAB
MATLAB: a tutorial introduction
=== One day Course ===
21 November 1994
Applied Mathematics and Operational Research Group, Royal Military
College of Science, Shrivenham, Wilts.
The course is specifically designed for scientists, engineers and
lecturers who either use routine numerical/matrix calculations in
their specific application area or teach the subject at various
levels. No specialist knowledge of programming or computer science is
required, but participants are expected to have basic knowledge of
computing and to be educated to HNC or degree level.
The course provides hands-on experience of the MATLAB package,
followed by an in-depth presentation of case studies dealing with
specialist topics from Signal Processing, Control System Design,
Numerical Computations, Splines and Optimisation. Most of the
afternoon is devoted to tutorials and the participants will have an
opportunity to work on a topic of their own choice.
The course lectures will be given by the teaching and research staff
of the Applied Mathematics and Operational Research Group under the
direction of Dr Venkat Sastry with the assistance of other RMCS
colleagues.
This one-day course forms part of a longer course entitled Re-usable
Software - Systems, Libraries and Packages, 21-25 November 1994 which
also covers Mathematica, PAFEC, NAGFE, SENAC and graphics packages.
