Subject: Question About Associated Legendre Functions
I am looking for publicly available code to compute first and second
kind associated Legendre functions when the argument is greater than 1.
While I have CACM algorithm 259 from netlib, I was wondering whether
anyone has an actual, tested, functioning code for this task.
Thank you in advance,
Eric Miller

Subject: History Has Got It Right
As I was flipping through an old issue of SIAM Review,
23(1), Jan 1981, I stumbled across a book review which makes
interesting (re)reading.
The book is "LINPACK User's Guide. By J. J. Dongarra, J. R.
Bunch, C. B. Moler, G. W. Stewart. SIAM, 1979. 2nd Printing
1980, viii + 344 pp." and the reviewer is Prof. B. N. Parlett.
Let's hear him, speaking almost two decades years ago:
"It may seem strange that SIAM should publish and
review a users' guide for a set of [170] Fortran programs.
Yet history will show that SIAM is thereby helping to foster
a new aspect of technology which currently rejoices in the
name mathematical software. There is as yet no satisfying
characterization of this activity, but it certainly concerns
the strong effect which a computer system has on the efficiency
of a program.
...
"I was impressed by the diagrams which give the relative
timings of the codes in 24 different computing environments.
The accompanying discussion indicates the complications
involved in the quest for efficiency. Indeed, it is the high
status accorded to the testing phase, and the way in which
those results were able to influence the design of the package,
that makes both LINPACK and its precursor EISPACK (for eigenvalue
calculations) such striking landmarks in the vast realm of
scientific computation."
With hindsight, we can definitely say that SIAM got it right.
And Parlett himself was right in his assessment! Today, mathematical
software plays an important role in its own right. While developing
a software, we appreciate how useful we can link to a library
installed locally, how great we can surf a web repository, click and
pick a piece of code vital for our work, how we can take or share
bits and pieces of valuable software through such specialized
journals as ACM-TOMS/CALGO and Numerical Algorithms.
Early mathematical software libraries have established trends
for others to follow, and other unexpected benefits have been reaped.
For instance, out of LINPACK and EISPACK came MATLAB, which grew in
leaps and bounds and is today an indispensable tool for any
self-respecting computational scientist.
Thanks to these early insight and vision, considerable progress
has been made, providing us equipment and understanding with which
to face new challenges, of which Problem-Solving Environments
constitute today an illustrative case in point.

FIRST ANNOUNCEMENT, CALL FOR PAPERS AND SESSION CO-ORDINATORS
MODELLING AND SIMULATION SOCIETY OF AUSTRALIA AND NEW ZEALAND INC., MODSIM
1999 MEETING
THEME: MODELLING THE CHANGING STRUCTURE OF AGRICULTURAL, HYDROLOGICAL,
TOURISM AND SOCIO-ECONOMIC SYSTEMS
Overview:
The 1999 Meeting of the recently extended Modelling and Simulation Society
of Australia and New Zealand Inc., will be hosted by the Department of
Economics and Waikato Management School, University of Waikato, Hamilton,
New Zealand over the period 6-9th December 1999. Hamilton is some 120
kilometres south of Auckland in the primarily dairy-based economy of the
mid-North Island. It is also an easy one-hour drive to the premier
tourist centre of Rotorua, which, as can be seen below, will be a feature
of the four-day meeting. Key-note presentations and contributed sessions
will be held in the Waikato Management School buildings on the University
of Waikato Campus. These modern facilities and attractive venue offer an
ideal location for the Meetings. Participants will be offered the choice
of University accommodation, some four minutes walk from the main lecture
theatres or an extensive list of motels/hotels located in the city centre.
The theme of the Meeting, which will be the inaugural meeting in New
Zealand, will draw-upon the unique characteristics of the New Zealand
environment, culture and economy. The Local Organising Committee, with
joint Convenors, Professor Les Oxley and Dr. Frank Scrimgeour, (Economics),
have involved representatives from AgResearch, the Forest Research
Institute and NIWA which we expect will add extra coverage to the 1999
Meetings.
Programme:
The 1999 Meetings will comprise the following structure. Days One and Two
will comprise key-note and parallel contributed paper sessions held at the
Waikato Management School. Day Three will comprise a morning of scientific
sessions held in Rotorua (all participants will be transported from
Hamilton to Rotorua by coach), followed by a choice of afternoon of visits
to either local areas of interest including, geothermal 'natural wonders,
geothermal power stations and trout and natural flora parks. The evening
will comprise The Meetings formal dinner and prize giving, following by
return transport to Hamilton. Day Four will follow the pattern of the
first two days. Bound and fully refereed conference proceedings will be
provided as per previous Meetings.
The Local Organising Committee wishes to follow the successful
initiatives of the 1997 Meetings by actively encouraging potential Session
Co-ordinators to contact the Committee with suggestions for potential
Topics for the Meetings. Email, mail and WWW addresses for these and
other interested parties are provided at the end of the piece. Please
feel free to publicise these addresses and the existence of the Meetings
via any group or personal WWW outlets.
Further information:
A Meetings WWW page is under construction at http://www.waikato.ac.nz/depts
/econ/modsim99 and a dedicated email address at MODSIM99@waikato.ac.nz.
Updated information including a list of key-note speakers, registration
fees and submission details and deadlines will be available by mid-1998
and will be publicised both via the WWW page outlets and hard-copy
leaflets and posters. Those who would be willing to distribute such
material could usefully contact either of the Convenors listed below.

Teaching Assistant Positions / Postdoctoral Position(s)
The Seminar for Applied Mathematics (SAM) will have several open positions.
These are teaching assistant/postdoctoral positions.
In both cases the successful candidate has to give tutorials. Initially this
can be done in English but after at most one year it should be done in German.
On the postdoctoral level the candidate is supposed to do research and support
research in applications areas of the SAM. Teaching assistants are supposed to
work towards the Ph.D. degree in addition to the regular teaching. The main
research areas of the SAM are numerics of partial differential equations,
especially hyperbolic nonlinear conservation laws with applications in fluid
mechanics, finite element methods and boundary element methods. At least two
positions will be involved with research projects, one on the inverse
formulation of the Euler equation of gas dynamics, the other one is concerned
with Large Eddy Simulation.
