Subject: Change of Address for Moler
A couple of weeks ago, I made an announcement here that
The MathWorks, the MATLAB companay, was looking to fill several
positions, including one for a numerical analyst. Now, I've
decided to take that slot myself. I'm one of the founders of
MathWorks, and have always been a consultant to the company, but
now I'll be a full time employee. For a while at least, I'll
be working out of my home in California, even though MathWorks
headquarters is in Massachusetts. (There are already a couple
of other MathWorks developers in the Bay Area.) My address and
phone number are:
Cleve Moler
The MathWorks
325 Linfield Place
Menlo Park, CA 94025
415-323-4412
My electronic address is "moler@mathworks.com". If your mailer
can't find the route via uunet to mathworks.com, you can still
use "na.moler@na-net.stanford.edu".

Subject: Some Corrections to EISPACK
We've recently come across a couple of minor bugs in EISPACK.
They only affect the results in rare situations. The corrections
to HQR, COMLR2, and COMQR2 repair errors introduced in going to
Edition 3, while the correction to BANDR substitutes more robust
coding to avoid overflow.
[Editor's Note: The changes have already been made in the source
code available from netlib@research.att.com and should be made soon
in netlib@ornl.gov. --Cleve]
HQR (DO-loop indices)
DO statements
do 200 j = k, n
do 210 i = 1, j
do 230 j = k, n
do 240 i = 1, j
should be replaced, respectively, by
do 200 j = k, EN
do 210 i = L, j
do 230 j = k, EN
do 240 i = L, j
COMLR2 and COMQR2 (DO-loop indices)
DO statements
do 840 i = 1, enm1
do 820 j = ip1, n
do 880 jj = low, enm1
should be replaced, respectively, by
do 840 i = 1, N
do 820 j = I, n
do 880 jj = low, N
BANDR (Overflow protection)
Line
S2 = 1.0D0 / (1.0D0 + B1 * B2)
should be replaced by
IF (ABS(B1) .GT. 1.0D0) THEN
U = 1.0D0 / B1
S2 = U / (U + B2)
ELSE
S2 = 1.0D0 / (1.0D0 + B1 * B2)

Subject: Third European Conference on Multigrid Methods
ANNOUNCEMENT AND 1ST CALL FOR PAPERS
for the
THIRD EUROPEAN CONFERENCE ON MULTIGRID METHODS
OCTOBER 1 - 4, 1990
BONN, WEST GERMANY
organized by: Gesellschaft fuer Mathematik und Datenverarbeitung (GMD)
Chairmen:
Ulrich Trottenberg GMD and University of Cologne

Themes:
The conference, continuing the sequence of conferences in 1981 and 1985,
will again bring together specialists and others with interest in the
general area of multilevel methods.
Themes of the conference will range from basic research to industrial
applications, with special emphasis on
- adaptivity
- parallel computation
including such subjects as adaptivity of grids and of discretization,
parallelization and efficient implementation of multigrid algorithms on
new computer architectures and domain decomposition techniques.
All fields of application are welcome; special topics will be
- computational fluid dynamics
- device simulation
- porous media flow
- statistical physics

containing title and abstract (maximum 1 page), as well as name and
address of the author(s), should be sent together (3 copies) to the
conference chairmen (use mailing address of the conference secretariat).
Deadline for the receipt of abstracts is March 15. Notice of acceptance
will be given by May 15. Selected contributions will be published as
full papers in the conference proceedings (to appear in the Birkhaeuser
Verlag, Basel). The deadline for the submission for these full papers

secretariat. (Order registration form from address below.) The
conference fee is DM 400,- for advanced registration (to be payed by
July 15th) and DM 480,- after July 15th, 1990. For a limited number of
students conference attendance at reduced fee is possible. Students

Subject: Positions at University of Alabama at Birmingham
FACULTY POSITIONS AVAILABLE
UAB
University of Alabama at Birmingham
The Department of Computer and Information Sciences invites applications for
tenure-track positions available fall 1990. Rank open. The Department
administers programs at the B.S., M.S. and Ph.D. levels. Parallel processing
and artificial intelligence are the two major research directions of the
Department. Therefore, applicants who have research interests in these two
areas are of special interest as well as those who are interested in the
integration of these areas with the areas of database systems, numerical
computing or graphics/image-processing.
The Department research laboratory equipment includes a variety of Sun
workstations and a 30 processor Sequent Balance 21000 parallel computer as
well as access to the Alabama Supercomputer Network Authority Cray XMP/24.
The Department is also a university affiliate of the Advanced Computer
Facility at the Argonne National Laboratory providing access to a variety
of parallel machine architectures. Opportunities are also available for
collaboration with biomedical researchers in the UAB Medical Center.
Birmingham is a major metropolitan area of almost 900,000 and is a
southeastern center of finance, telecommunications and medicine. It
was recently selected by Newsweek magazine as one of the top ten cites
in the U.S., characterizing Birmingham as "a friendly, prosperous city
feeding on a high-tech blend of biomedical research, engineering and
telecommunications". UAB is a comprehensive sunbelt university and
ranks among the top 20 public universities in the U.S. in terms of
federal research and development. In 1989 UAB surpassed the $100M per
year mark in active grants and contracts. Enrollment is over 15,000
students.
Applicants should hold the Ph.D. in computer science or closely related
field and have a strong interest in both research and teaching.
Interested individuals should send a resume and names of three references
to Dr. Warren T. Jones, Department of Computer and Information Sciences,
UAB Station, Birmingham, AL 35294. UAB is an Affirmative Action/Equal
Opportunity Employer.
