Subject: Happy Birthday, Bill

February 1 is Bill Gear's 60th birthday though we will be observing it
on April 1 (no foolin') at Stanford. I've been fortunate to know Bill
40 years. Not only has he worked on a wide range of scientific problems
but he has shown unusual leadership qualities in many capacities So
many happy returns, Bill. Thanks for everything and I hope you can
continue for many years. We'll have a blast in April!

Subject: Numerical Computation in CS Departments

In the NA Digest of January 29, Michael Overton writes
"Years ago many Computer Science Departments had a required numerical
computing class. NYU and McGill still do but many other Departments
have long dropped the requirement." Michael Overton then tells what
he does to interest computer scientists in numerical computation.

In the Computer Science Department at Columbia University,
numerical computaion is required for undegraduate majors and for all
PhD students. A substantial portion of the graduate course is devoted
to continuous computational complexity, that is to computational
complexity over the reals. Another portion of the course is devoted
to implications of finite precision floating point arithmetic.

Course evaluations indicate that students like the course.

I use my own class notes and selected readings for the course. My
colleagues and I have written a number of recent expository papers
on continuous computational complexity which I would be pleased to
mail to those indicating interest.

Subject: Introducing the MATLAB ODE Suite

The MathWorks is pleased to announce the availability of a preliminary
version of the MATLAB ODE Suite, a collection of M-files developed by
Lawrence F. Shampine and Mark W. Reichelt for solving ordinary
differential equations.


- non-stiff system solvers (ODE45, ODE23, ODE113)
(ODE45 and ODE23 are completely new codes)

- stiff system solvers (ODE15S, ODE23S)
(with support for sparse systems and mass matrices)

- a powerful new solver syntax

- control of integration options (ODESET, ODEGET)

- optional specification of output points

- optional integration backwards in time

- installable output functions

- a graphical demo (ODEDEMO)

- interfaces to SIMULINK integrators and systems

- 20 example ydot files


The ODE Suite is available by ftp from in the
/pub/mathworks/toolbox/matlab/funfun directory. The directory also
contains a README file with more information on the ODE Suite M-files,
and, the postscript version of a technical report
describing the algorithms in detail.

Software Requirements

The ODE Suite requires MATLAB 4.2c.

Subject: Adaptive Simulated Annealing Research Project

An approach to using ASA_SAMPLE to perform integrals was added to the
Adaptive Simulated Annealing (ASA) code. This is in a crude form now,
but I have put it into the latest ASA version to promote some interest
in further developing such code. As is evident by some recent files in
my archive, I have developed a path-integral code, PATHINT, which I
have used for several publications. Such code is extremely useful for
nonlinear Fokker-Planck systems, which arise in many disciplines, e.g.,
many fields of physics, chemistry, biology, finance, chaos + noise,
neuroscience (as in my SMNI papers, my primary motivation for
developing the ASA and PATHINT codes).

The latest Adaptive Simulated Annealing (ASA) code and some related
(p)reprints can be retrieved via anonymous ftp from [] in the /pub/ingber directory.

Subject: Revision of CLAWPACK

Revision of CLAWPACK (Conservation LAWs software PACKage)

I am in the process of making some substantial changes to clawpack, which
includes some restructuring as well as improvement and extension of some of the
routines. The new version will be more flexible and allow the solution of
certain hyperbolic systems that are not in conservation form, for example.
In the process of doing this, I would like to consider
any suggestions or complaints that current users of clawpack
might have. Please send comments or suggestions to

As an indication of what changes I currently have in mind, I have created a
new version of a limited set of routines and applications. This is
available for testing by anonymous ftp from
in the file pub/rjl/programs/newclaw.tar.Z, or you can browse through it
with a web browser from the URL
In particular, see the file newclaw/Changes.

University Lecturership in Numerical Analysis
(in association with New College)

Applications are invited for the above post, tenable from 1
October 1995. Stipend will be according to age, on the scale
L14,756 - L27,473 per annum. In the first instance the
College will elect the successful candidate to a Supernumerary
Fellowship, with no tutorial duties or stipend; on the
retirement of Dr. D.F. Mayers (not later than September 1998)
the Supernumerary Fellow will be elected to an Official
Fellowship with tutorial duties and a stipend on the scale
L2,845-L5,406 per annum.

Candidates should have a broad range of interests and teaching
ability in numerical analysis; research interest and
experience in areas such as numerical linear algebra,
optimisation and parallel algorithms would be an advantage.

The successful candidate will join an active research group
whose interests cover the whole range of numerical analysis:
the main thrust at present is in the numerical solution of
partial differential equations by finite element, finite
volume, finite difference and spectral methods, together with
applications in computational fluid dynamics and
electromagnetics; and it is out of this that the research in
linear algebra (especially on multigrid and conjugate gradient
methods), optimisation, approximation, domain decomposition
and parallel algorithms largely springs.

Further particulars, containing details of the duties and full
range of emoluments and allowances attaching to both the
university and the college posts, may be obtained from the
Director of the Computing Laboratory, Wolfson Building, Parks
Road, Oxford OX1 3QD (telephone: Oxford (01865) 273885; fax
