Szyld Date: Mon, 20 Aug 90 15:16:08 EDT Subject: New Address for Daniel B Szyld Dear Friends and Colleagues: My new address is Daniel B Szyld Department of Mathematics Temple University Philadelphia, PA 19122 (215) 787 7288 szyld@euclid.math.temple.edu Please make the appropriate changes in your records and in the mailing lists. Thank you. ------------------------------ From: Eric Grosse Date: Fri, 24 Aug 90 15:55 EDT Subject: Netlib News: Greetings This is the first in a quarterly series of columns about netlib. Never heard of it? Then read: Jack J. Dongarra and Eric Grosse, ``Distribution of mathematical software via electronic mail'', Communications of the ACM (1987) 30, 403-407. Or, if that's too much trouble, just send e-mail containing the line ``help'' to the Internet address netlib@research.att.com or uucp address uunet!research!netlib. A few minutes later, assuming you have speedy mail connections, you will receive information on how to use netlib and an overview of the many mathematical software libraries and databases in the collection. Each column in this series will start with a background discussion of how netlib is run, applications in other fields, security horror stories, and so on. The second half of column will briefly describe recent additions to the collection and important updates of old codes. If there are specific topics you would like to see addressed in future issues, let me know. Strictly speaking, this column only applies to the netlib running at Bell Labs in New Jersey. If you're accessing the copy at Oak Ridge, or Oslo, or Wollongong, or perhaps elsewhere, then the files should either be there already or will show up shortly when our semi-automatic procedures resynchronize the collections. This first column provides a nice opportunity to publicly thank our sponsors. The U.S. National Science Foundation provided an early grant to help get us started, and implicitly helps by funding the national network. AT&T has donated machine resources, communication facilities, and my time. Sequent generously loaned a machine, operated by Oak Ridge National Laboratory, to support netlib. The Norwegian government, through a grant to Petter Bjorstad, purchased a machine to provide service to Europe. The ACM agreed to redistribution of its Collected Algorithms, and Algorithms Editor R. J. Renka arranged for prompt updates. SIAM contributed its membership database. To all these groups and the many others who contribute, the community owes thanks. Naturally, this thanks should not be expressed in the form of a lawsuit if you're unhappy with some piece of software. None of the organizations had anything to do with the content, and even the editors make no claims about the suitability of the software for any purpose. That's the meaning of the disclaimer ``Anything free comes with no guarantee.'' On the other hand, don't be completely frightened off by this warning. The mathematical algorithms in netlib include some of the most sophisticated and robust methods to be found anywhere. Just remember that a healthy skepticism is appropriate when you get software from any source. *** Recent additions *** PLTMG edition 6.0 is a package written by Randy Bank, UCSD, for solving elliptic partial differential equations in general regions of the plane. It features adaptive local mesh refinement, multigrid iteration, and a pseudo-arclength continuation option for parameter dependencies. The package includes an initial mesh generator and several graphics packages. Full documentation can be obtained in the PLTMG User's Guide, newly published in the SIAM Frontiers in Applied Mathematics series. This library consists of a number of Fortran files and a few C files, most of which (aside from the graphics) are machine independent. Since the package is rather large, it has been made available via ftp research.att.com, for those who have Internet access. Log in as anonymous and cd dist/pltmg. You must uncompress the .Z files once you have a copy of them. Someday we plan to make all of netlib available by ftp. Version 2.1 of the dhrystone benchmarks in Ada, C, and Pascal is a new release from Reinhold Weicker, replacing the earlier (1984) version. Source code and runtime libraries for the Fortran-to-C converter are now available, courtesy of Stu Feldman of Bellcore, David Gay and Norm Schryer of AT&T Bell Labs, and Mark Maimone of CMU. Since last fall, you have been able to exercise f2c by sending netlib a message whose first line is execute f2c and whose remaining lines are the Fortran 77 source that you wish to have converted. Return mail brings you the resulting C, with f2c's error messages. During the initial experimental period, incoming Fortran is being saved in a file. Don't send any secrets! The na-digest directory is an archive of the NA-NET Digest, an electronic mailing moderated by Gene Golub and Cleve Moler. File names are of the form v87n1. (Starting with 1990, names are of the form v90n01, to simplify sorting.) VFFTPK Version 2.1, May 1990 is a vectorized package of Fortran subprograms for the fast Fourier transform of real sequences, by Roland Sweet and Linda Lindgren, NIST Boulder, and Ronald Boisvert, NIST Maryland. It is a vectorization (for transforming multiple sequences) of the package FFTPACK (Version 3, June 1979) written by Paul N. Swarztrauber of NCAR. This was written 27 July 1990 and is intended to be co-published in the electronic NA-NET Digest, the SIAM News, and the SIGNUM Newsletter. The author is in the Computing Science Research Center at AT&T Bell Laboratories, Murray Hill NJ 07974, USA. He can be reached by email at ehg@research.att.com. ------------------------------ From: SIAM Publications Department Date: Thu, 23 Aug 90 14:05 EDT Subject: SIAM Journal on Applied Mathematics Table of Contents SIAM Journal on Applied Mathematics V0l. 50, No. 6, December 1990 A Localized Approximation Method for Vortical Flows R.
