**Subject: Orthogonal Polynomials**

Many NA-Netters responded to my question, and since a desire for more

answers was expressed here recently, I've summarized the replies below.

First, I should apologize for stating the question badly, and worse,

making a mistake in the statement. (This did not prevent the right

people from answering the right question!) So I'll rephrase the question

as I should have asked it, and introduce it with some supporting

material.

Introduction:

Classical orthogonal polynomials are defined for the intervals [-1,1],

[0,\infty] or [-\infty,\infty]. Orthogonality only determines the

polynomial up to a nonzero constant factor, so they are standardized in

various ways: Legendre and first kind Chebyshev polynomials are

standardized to have the value 1 at x=1, second kind Chebyshev to have

value n+1 at x=1, etc.

In Table 22.2 of the Handbook of Mathematical Functions, some polynomial

families are standardized in more than one way. Interestingly enough,

only one of the preferred standardizations (Laguerre) leads to

orthonormal polynomials.

For computational purposes, the most convenient standardization (used

by Walter Gautschi in his ORTHPOL package, ACM TOMS 1994) is to use monic

polynomials.

When doing actual computations with orthogonal polynomials, several

numbers are of importance, of which the leading coefficient and the norm

are the most prominent.

The problem:

Take for example the Chebyshev polynomials. As usually standardized, they

have norm pi/2, except T_0 which has norm pi. Nice numbers, not big, not

small. But the leading coefficients go 1, 1, 2, 4, 8, 16, ... If you're

using single precision on an IEEE floating point processor, you run into

overflow at n=128. If we use leading coefficient 1 as Gautschi does,

then the norms go down by a factor 2 each time, and we run into underflow

at n=128. (Or even at n=64, if you need to use norm-squared.)

The question:

Somebody has discussed this problem and noted that the solution is to

scale the interval to [-2,2]. Who? Where?

Why is that solution correct?

There is a whole theory of 'capacity' of a set, important enough to be

one of the 450 subjects selected as main articles in the Encyclopedic

Dictionary of Mathematics, Second Edition. (But unknown to me until

kindly pointed out by some NA-Netters.) It's rather technical to define.

Henrici (Applied and Computational Complex Analysis, Volume 3, p374) has

the easiest definition in the case when the boundary of the set is a Jordan

curve G:

you map the exterior of G onto the exterior of the unit circle by a

function f such that f(\infty)=\infty, and with Laurent series of the

form

f(z) = a_1 z + a_0 + a_{-1}z^{-1} + ... with a_1>0.

Then the capacity of the set bounded by G is 1/a_1.

The best explanation of what effect capacity has, came from Nick Trefethen:

"But the phenomenon you mention is surely tied to the capacity, in the

sense of complex analysis, of the set you're dealing with. [-2,2], like

the unit disk, is a set of capacity 1. Presumably in general, if you do

Faber expansions on a set in the complex plane, you want to scale it to have

capacity 1 if exponentially growing or shrinking coefficients are to be

avoided. Taylor series on the disk and Chebyshev series on [-2,2] are

special cases."

The reference:

I received the following pointers:

L. Reichel, Newton interpolation at Leja points, BIT 30 (1990), 332-346.

L. Reichel, Fast QR decomposition of Vandermonde-like matrices and

polynomial least squares approximation, SIAM J. Matrix Anal. Appl.,

12 (1991), pp. 552-564.

L. Reichel and G. Opfer, Chebyshev-Vandermonde systems, Math. Comp., 57

(1991), pp. 703-721.

D. Calvetti and L. Reichel, Fast inversion of Vandermonde-like matrices

involving orthogonal polynomials, BIT, 33 (1993), pp. 473-484.

D. Funaro, Computational Aspects of Pseudospectral Laguerre Approximations,

Applied Numerical Math. 6 (1989/90) 447-457

I can't swear that any of these is the one I saw. But they certainly

use the trick mentioned, or something similar. Perhaps the first would

explain the sense of leja vu that I felt when encountering the phenomenon.

Other useful hints:

Several respondents made me realize how badly I phrased the question by

gently reminding me that one should evaluate orthogonal polynomials by

the recurrence formula, and series involving these polynomials by

Clenshaw's algorithm. All were tactful enough to refrain from pointing

out that I should have said 2^n instead of 4^n.

Thanks to all who responded.

**Subject: CLAWPACK, Conservation LAWs software PACKage**

CLAWPACK -- Conservation LAWs software PACKage

Version 1.0 of CLAWPACK is now available from netlib. This is a package of

Fortran subroutines for solving hyperbolic systems of conservation laws in one

and two space dimensions. (Future versions should include 3D.) High resolution

flux-limiter methods are used, based on solving one-dimensional Riemann

problems. In two dimensions, multi-dimensional wave-propagation methods are

used. The current version supports only uniform Cartesian grids in

rectangular domains, and is intended primarily as a research and teaching

tool. The modular form should make it easy to modify and experiment with

other methods, as well as to apply it to new problems.

The code requires that the user supply a Riemann solver for the problem

being solved and also a subroutine that implements the boundary conditions.

Source terms can also be handled (via Strang splitting) in which case an ODE

solver for the source terms must also be supplied. Several examples of

different Riemann solvers are included with the package, including e.g.,

advection equation, Burgers' equation, Euler equations, isothermal

equations, shallow water equations. Various different boundary conditions

are also demonstrated, such as periodic, inflow, nonreflecting, and solid

walls. Numerous example drivers are included to demonstrate the use of

these subroutines. Matlab m-files are included to graphically display the

output, or they can be used as a model for writing graphics routines in

other languages. Documentation is included in the package, including the

postscript file for an introductory paper on the package.

The package can be obtained from netlib, where it resides in the library

pdes/claw. This directory currently contains:

index the index

clawpack the basic package, with 1d, 2d routines and many examples

doc documentation (postscript files of papers, slides)

advection applications of clawpack to 2d advection equations, with

examples from a recent paper on this subject (in doc).

nozzle application of clawpack to the quasi-1d nozzle problem.

vBurgers viscous Burgers' equation, with diffusion equation as source.

L-domain L-shaped domains, such as the forward facing step problem.

My hope is that a library of more sophisticated applications

will be gradually built up, and contributions from other users will be

gratefully accepted.

The package may be obtained by anonymous ftp from netlib.att.com, where it

resides in netlib/pdes/claw. The file netlib/pdes/claw.tar is a tar file of

the entire directory. Files can also be obtained by sending e-mail to

IMA Journal of Mathematics Applied in Business and Industry

Dear Colleague,

You will, I am sure, all be familiar with the two Oxford University Press

journals: IMA Journal of Numerical Analysis and Applied Mathematics.

You may, however, not know of the IMA Journal of Mathematics Applied

in Business and Industry or what its aims are.

The IMA Journal of Mathematics Applied in Business and Industry was founded

9 years ago and is now well established publishing high quality papers in

Operational Research, Decision Theory, Queueing Theory and other aspects

of Business applications.

I was asked to join Professor Thomas as joint Managing Editor to

enhance ``Mathematics Applied in Industry''. Thus I wish to stress that,

in addition to ``Business Applications'', this journal is interested and

has always been interested in publishing papers on Industrial Applications.

In particular, I am seeking papers on industrial case studies, mathematical

modelling of devices and processes, and using mathematical models as an

aid to the design of new products. Relevant papers could, for example,

be in the area of the mathematics underpinning computer aided design,

computer aided manufacture, or discrete event simulation. I would

particularly welcome papers which describe interdisciplinary projects in

which mathematics played a significant, or even crucial role; papers in

which mathematics was a contributory factor in a problem solving exercise;

or papers which contained the novel application of even standard mathematics

to a new area of engineering or science which hithertofore had never

received a mathematical treatment.

I would be very grateful if you could mention the industrial aspect of

this journal to your colleagues in mathematics, engineering mathematics,

physics and electrical engineering.

Yours sincerely,

Professor Sean McKee

**Subject: BibNet: Project Announcement**

BibNet

A Bibliography Network Project

Announcement and solicited contributions

BibNet is a public-domain bibliography data base in BibTeX format.

The data base contains two types of bibliographies:

- by author (i.e. an author's list of publications), and

- by subject.

This initiative is a step toward sharing information electronically,

and it allows scientists to:

- provide complete and updated information on their own work,

- find information about ongoing research or specific topics,

- have an efficient pointer to electronically accessible material, and

- simplify the work of preparing publications.

The BibNet data base is maintained at the University of Utah, on

ftp.math.utah.edu, where the files are stored in /pub/bibnet. It is

mirrored nightly from there to a few other Internet archive sites.

BibNet is accessible through anonymous ftp, Netlib, Mosaic, Gopher and

e-mail. E-mail to the address:

bibnet-info@math.utah.edu

with the subject or body

send readme from bibnet

will return information and instructions on:

- features of the BibNet bibliography database,

- access and retrieval of bibliographies, and

- contributing new or updated bibliographies.

WE SOLICIT CONTRIBUTIONS !!

New or updated contributions will be standardized and checked and the

bibliographies will be incorporated in the BibNet data base.

We hope that the NaNet community will understand the convenience

and power of a bibliography database.

We anticipate that the success of this initiative will likely

generate motivation to render the work as automatable as possible,

to increase the features of this service, and to scale the project

to other fields.
