**Subject: Code Tex Macros**

Every so often I am asked how I put numbers in front of lines of code

in my books and papers and how I manage to label code fragments like

equations. Since the tex macros are rather simple, I decided to clean

them up and distribute them. The result is the environment `code'. A

directory containing the style file may be downloaded from

ftp://thales.cs.umd.edu/pub/misc/code.tar

In addition to code.sty, the directory contains some examples from an

accompanying expository paper, "The Gram-Schmidt Algorithm and Its

Variants," written especially for the purpose because Gram-Schmidt has

lots of variants use as examples.

**Subject: MOORe Tools, A New MATLAB Package for Regularization**

MOORe Tools - a new Matlab package for regularization

MOORe Tools is a new Modular and Object Oriented Regularization

Toolbox written in Matlab, suited for analysis and solution of large-scale

inverse problems. It can be viewed as the "next generation" of the

Regularization Tools package (developed in the early nineties).

MOORe Tools includes a variety of (mostly iterative) regularization

methods, such as:

- Tikhonov regularization, solved by applying CGLS to the

least squares formulation;

- Tikhonov regularization with p-norms (instead of 2-norms),

solved via a reweighted least squares algorithm;

- truncated SVD regularization;

- regularizing Krylov subspace iterations (CGLS, GMRES, etc.).

All regularization methods are based on an object oriented formulation

with linear operators working on vectors; the operator can be a

point-spread function, a Green's function, a convolution operator, etc,

while the vector can represent an image, a density distribution, a signal,

etc.

A few new large-scale test problems are included:

- steady-state heat distribution in 2D;

- 2D interpolation from regular grid to arbitrary points;

- image deblurring with separable blur.

The Matlab package was developed by Michael Jacobsen as a PhD

project at the Technical University of Denmark. Both the package

and the associated PhD Thesis are available from the MOORe Tools

homepage, which is available via the URL

http://www.imm.dtu.dk/nag/software (click on MOORe Tools link)

The package was developed at the same time as the RestoreTools

package for image deblurring

http://www.mathcs.emory.edu/~nagy/RestoreTools/index.html

but MOORe Tools is designed as a more general package.

Users of the new package are welcome to send comments and bug reports

to me. Enjoy the new package.

**Subject: Nonlinear and Differential/Algebraic Equation Solvers**

SUNDIALS (SUite of Nonlinear and DIfferential/ALgebraic equation Solvers)

version 2.0 has been released under an open source BSD license.

SUNDIALS 2.0 consists of the following four solvers:

CVODE v.2.2.0 solves initial value problems for ordinary differential

equation (ODE) systems.

CVODES v.2.1.0 solves ODE systems and includes sensitivity analysis

capabilities (both forward and adjoint).

IDA v.2.2.0 solves initial value problems for differential-algebraic

equation (DAE) systems.

KINSOL v.2.2.0 solves nonlinear algebraic systems.

SUNDIALS was implemented with the goal of providing robust time integrators

and nonlinear solvers that can easily be incorporated into existing simulation

codes. Basic operations on vectors are isolated to a separate module,

for which the distributed package includes serial and parallel versions,

but the user can supply his/her own version.

The SUNDIALS solvers are written in ANSI C, with CVODE and KINSOL also

providing a FORTRAN to C interface. All solvers can be built in single,

double, or extended precision.

More information (description, documentation, changes in the current versions)

and download links can be found on the updated SUNDIALS web page:

**Subject: Hankel System with a Special Right Hand Side**

Dear NA readers,

I am working on the solution of systems of linear equations with a

Hankel matrix H = [a_(i+j-1), i,j = 1, ... ,n] and right hand side

[a_(n+i), i =1, ... ,n] . The aim is to perform the computations in

interval arithmetic.

I have already investigated the Berlekamp-Massey algorithm but it has a

poor performance when using interval arithmetic. I would highly appreciate

receiving hints to other existing algorithms for such linear systems.

Note that the Levinson algorithm and the Durbin algorithm are not

applicable since the system considered does not enjoy a symmetry w.r.t.

the antidiagonal.

Sincerely,

Ismail Idriss

**Subject: Seeking Linear Algebra for Continuous Functions Literature**

Dear NA Digest Readers:

My name is Zachary Battles and I am currently developing a system to

perform linear algebra on continuous functions and operators.

One particular area of interest to me is linear algebra for matrices

whose columns are continuous functions. For example, one might take the

QR factorization of a matrix with columns 1, x, x^2, ... to construct

Legendre polynomials. While this material is not new, there doesn't

seem to be many references in the literature. Other than de Boor,

Stewart and Trefethen, can someone point me to others who might have

written about this subject? Please respond to battles@comlab.ox.ac.uk.

Thank you for your assistance.

**Subject: Staff Position at Lawrence Berkeley National Laboratory**

Job opening in the Accelerator Modeling and Advanced Computing Group at

Lawrence Berkeley National Laboratory

Summary: The Accelerator Modeling and Advanced Computing (AMAC) Group in

LBNL's Center for Beam Physics is a world leader in applying high-end

computing to solve challenging, strategically important problems in

accelerator science and technology. Its activities involve developing

and utilizing parallel codes to simulate a variety of accelerator

systems and beam phenomena, including intense beams in linacs and rings,

beam-beam effects, collisional effects, electron-cloud effects, high

brightness electron guns, coherent synchrotron radiation, free electron

lasers, ion sources, and laser/plasma accelerators. The highly

nonlinear, multi-scale, and many-body aspects characteristic of future

design problems account for their extreme technical difficulty. Their

solution requires a combination of methods from modern accelerator

theory and nonlinear dynamical systems theory, computational science,

computer science, applied mathematics, and numerical analysis. AMAC is a

co-lead laboratory on a DOE Scientific Discovery through Advanced

Computing (SciDAC) project, and is also involved in R&D activities

associated with the proposed Rare Isotope Accelerator project. AMAC is

presently seeking a postdoctoral scientist, with a strong background in

scientific computing, to participate in research activities related to

the large-scale simulation of intense charged particle beams in

accelerators.

Qualifications: Essential-Ph.D. or equivalent experience in a discipline

of the physical sciences (including but not limited to accelerator

physics, plasma physics, or astrophysics), with experience in high-end

computing in that discipline, and a record of publication in that

discipline; Experience in developing and implementing parallel software

for large-scale scientific simulation. Demonstrated ability to

collaborate with others and work effectively in a team environment.

For Further Information: Directions on applying for this position can be

found at http://jobs.lbl.gov/ . The position is in the Accelerator &

Fusion Research Division, requisition # 017260. For further information
