Subject: Wilkinson's sparse matrix definition
In an earlier NA Digest (vol 7, number 6, Feb 4, 2007), regarding Wilkinson's
definition of a sparse matrix, I stated that he seemed to have never published
his definition writing. Sven Hammarling has fortunately proved me wrong, by
finding a printed definition from 1971.
In "Introduction to Part II, The Algebraic Eigenvalue Problem," Handbook for
Automatic Computation, Vol II, Linear Algebra, Spring-Verlag, 1971, edited by
Wilkinson and Reinsch, page 191, Wilkinson states:
"A variety of factors enter into the determination of the most efficient
algorithm for the solution of a given problem; the following are perhaps
the most important. ...
(iv) The matrix may be *sparse*, either with the non-zero elements
concentrated on a narrow band centered on the diagonal or alternatively
they may be distributed in a less systematic manner. We shall refer
to a matrix as *dense* if the percentage of zero elements or its
distribution is such as to make it uneconomic to take advantage of their
presence."
Emphasis is in the original (in italics). The preface of the book is dated
October 1970, which correlates nicely with Jim Bunch's recollection of
Wilkinson's definition stated to him personally in 1969 or so.
He defines a sparse matrix by negation, since it's clear from (iv) that any
matrix is considered either sparse or dense. This is essentially the same as
he is quoted in [1]: "any matrix with enough zeros that it pays to take
advantage of them".
Wilkinson would have defined "economic" as saving both time and memory;
this can be inferred from his other work, where he constantly considered
both aspects of the algorithms he studied and developed.

MSRI Symposium on Climate Change: From Global Models to Local Action
Made possible by the generous support of Sea Change Foundation.
Global models based on current and past observations document the
reality of climate change caused by human activity, although the
details of when and what will happen where are far from clear. This
symposium will address the problems and research necessary to
translate these global, long-term predictions into local predictions
on shorter scales of time, where governments and businesses can act;
and will address the implications for industry and public policy now.
April 11, 2007: Public Symposium, Palace of Fine Arts, San Francisco
7:00pm-9:30pm
Confirmed Speakers:
Congressman Jerry McNerney
Orville Schell, Dean of the Graduate School of Journalism, UC Berkeley
The symposium will address several major challenges in climate
projection, including:
o The formulation of climate models
o The process of downscaling from global to local scales
o The derivation of climate statistics and secular trends
o The interpretation of climate as a dynamical system
o The construction of risk analyses for climate impacts
o The extraction of climate information for decision making

following disciplines is desired: control theory, optimization, model
reduction techniques, numerical analysis, computation for systems with
uncertain parameters (stochastic finite elements, polynomial chaos,
stochastic response surface methods), and/or Markov Chain methods.
Previous experience with applications of such methods for large, complex
engineering systems and large dynamic networks is highly desirable.
Besides technical excellence, very strong teaming and communications
skills, together with an entrepreneurial attitude towards innovation,
are essential. The minimal education requirements are a Ph.D. in
mathematics, computer science, or engineering, or an M.S. in the same
area supplemented by 5 years of industrial research post degree.
The System Dynamics and Optimization Group at United Technologies
Research Center works within integrated product development teams to
design, analyze, and implement systems solutions and conduct model-based
analyses for new products and processes. The traditional areas of
strengths of the group are multi-scale and parametric analysis of
nonlinear systems, modeling of thermo-fluids and reacting flows,
computational complexity reduction, advanced signal processing,
classification and decision support tools. Applications currently under
study include building security systems; advanced modeling environments;
uncertainty propagation through large, complex networks of systems; fuel
cell power plants and advanced fuel processing systems; refrigeration
systems; elevator positioning; decision support tools built upon
statistical and physics-based models of wear; and strategic business
decision support tools.
