If anyone can send me such a code via email then that would be ideal but I would gladly pay for any shipping or handling charges if snail mail were used instead. My email addresses are: UUCP: {uunet,ihnp2,allegra}utzoo!watmath!water!phcalamai ARPANET,CSNET,MILNET: phcalamai@water.uwaterloo.ca BITNET: phcalamai@water.BITNET My snail mail address is: Paul H.

No new features, but there should be one less bug. Mail to nanet@na-net.stanford.edu if there are any problems. Remember: mail to na@na-net.stanford.edu for submissions to the digest. nanet@na-net.stanford.edu for requests, questions, problems. If you cannot get to host na-net.stanford.edu then try routing through score.stanford.edu: na%na-net@score.stanford.edu or nanet%na-net@score.stanford.edu Those coming in through bitnet, csnet or uunet will *not* need the extra routing, but those on the Internet that are not running name resolution software will need the extra routing. The host score.stanford.edu does not support any NA-NET functions. It was announced about a year ago that we were moving off score.stanford.edu but that mail addressed there would work for a while. As of yesterday, mail to na.<anyone>@score.stanford.edu will get bounced with an error message. Everything should go to host na-net.stanford.edu (but of course you can route through intermediate machines). Also, updates to the NA list are currently back logged, and this should be rectified soon.

For example, the modern signal processing techniques of adaptive filtering and high resolution spectral analysis encompass a broad range of mathematical concepts from linear algebra and numerical analysis to parallel processing and the solution of inverse problems. The aim of this conference is to bring together mathematicians and signal processing experts with a view to exploring the many areas of mutual interest, addressing the important mathematical problems which arise in signal processing and identifying fruitful avenues for further research. It is hoped that the meeting will also provide a focal point for attracting more scientists and engineers into this exciting research field. The conference will comprise six non-overlapping sessions each featuring five or six spoken papers of a self-contained and partly tutorial nature, and a related poster session for papers which describe more specific research results and ideas in the area of interest. A very exciting social programme has been arranged which includes a civic reception and a buffet at St Mary's Guildhall,Coventry; a Medieval Banquet at Coombe Abbey and an optional visit to the Royal Shakespeare Theatre at Stratford-upon-Avon to see 'The Tempest'. Invited Speakers: R E Blahut, T E Curtis, B Arambepola, E R Pike, D M Titterington, J Besag, J Proakis, L Lacoume, J F Bohme, S Haykin, M Bellanger, B Friedlander, P Van Dooren, G Golub, V Vandewalle, L Elden, J Speiser, F T Luk, Y Robert. On Monday 12th December 1988 there will be a one-day tutorial course on "The Mathematics of Adaptive Filtering". Speakers: J E Hudson, J Proakis, J Speiser, F T Luk.

Contributions for the special issue are invited in any area in which matrix canonical forms play a role. New canonical forms motivated by modern applications, new approaches to calculating, interpreting, or applying old or new canonical forms, and surveys of theoretical and applied areas are all welcome. Papers should meet the usual publication standards of LAA and will be refereed in the usual way. The deadline for submission of manuscripts is November 1989, and publication of the special issue is expected about a year later. Papers may be sent to any of the three special editors of the matrix canonical forms issue: Roger A. Horn Department of Mathematical Sciences The Johns Hopkins University Baltimore, Maryland 21218 USA (msc_hrah@jhuvms.bitnet) Thomas J. Laffey Mathematics Department University College Dublin Dublin (4) Ireland (tlaffey@irlearn.bitnet) Russell L.

The term "matrix theory" is broadly interpreted and is meant to include those parts of the many subjects that have stimulated research about matrices over the years. In an effort to maximize the number of interested parties who can attend, the cost of attending is being kept to a minimum. Centrally located Salt Lake City International Airport is nearby and is serviced be most major US carriers. A limited number of on-campus housing slots will be available at a very low cost, along with an inexpensive meal plan of good quality. Nearby motels will offer a very affordable alternative. There will be no registration fee as such, although a nominal and optional donation to the Society and for daily refreshments will be solicited. In addition, within easy driving distance from Provo lie a large fraction of the many spectacular attractions of the Rocky Mountain West. In addition to Yellowstone, the Grand Canyon, Bryce Canyon and Zion Park are a host of lesser known, but nearly as enjoyable parks. A tour on either side of the meeting would be worth it by itself. A special concentration at the meeting on nonnegative matrices and related topics is to be modestly funded by the US NSA. Additional subsidy is being graciously provided by Brigham Young University and the time, effort and research funds of the organizers. We hope that you can make the meeting a success with your attendance. Please contact Wayne Barrett or any other organizer by electronic mail or in writing with your interest in attending. We hope you will do this soon, as this would be helpful for planning the program. A special issue of Linear Algebra and its Applications will be devoted to the meeting. This issue will contain only papers that meet the publication standards of the journal, and that will be approved in a normal refereeing procedure. Special editors of this issue are Wayne Barrett, Danny Hershkowitz, and Don Robinson. The organizers of the meeting are: Wayne Barrett Danny Hershkowitz Charlie Johnson Dept. Mathematics Dept.

Since this is the time of year that students are deciding where to apply for graduate study, we would greatly appreciate your bringing this information to the attention of any of your undergraduates who may be interested in our program. With many thanks Michael Overton GRADUATE STUDY IN NUMERICAL ANALYSIS DEPARTMENTS OF COMPUTER SCIENCE AND MATHEMATICS COURANT INSTITUTE OF MATHEMATICAL SCIENCES NEW YORK UNIVERSITY The Courant Institute of Mathematical Sciences offers a unique environment for graduate study in numerical analysis: - a strong and rich history of research in numerical analysis and associated areas of applied mathematics and computing; - an emphasis both on basic theoretical research and a wide variety of applications; - students may qualify for their graduate degree in either the computer science or the mathematics department. Graduate courses in numerical analysis are crosslisted in both departments; - the Courant Institute is part of New York University, located at Washington Square, in Greenwich Village, one of the most attractive and diversified neighborhoods in New York City. Applicants for both the Ph.D. and M.S. degrees should have strong undergraduate degrees in computer science, mathematics, or other applied science/engineering backgrounds. Fellowships and assistantships are available for a limited number of well- qualified students applying for full-time study for the Ph.D. degree. They provide full-time tuition and a stipend for living expenses and are renewable. Scores on both the general and subject tests of the GRE are required for all financial aid applications; all such applications must be received by mid-December.

The algorithm in SLEIGN, for example, is based on the solution of initial value problems, using an integrator having a built-in global error estimating capability.
