Subject: AX=LX

Dear NA-neters,

I would greatly appreciate any information on the following question:

Is there any standard iterative process in the space of square real or
complex matrices, M, for the computation of the solution (L,X) of the

A X =3D L X

X^T X =3D I,

(A, L, X are in M, I is the identity matrix, X^T is the transpose of X
and =
is diagonal) ?

Equivalently I am asking for an algorithm enabling the simultaneous
computation of all eigenpairs of a given matrix A.

Thank you in advance,

Mario M. Graca

Subject: Availability of HSL mathematical software

HSL (formerly the Harwell Subroutine Library)

We are delighted to announce the availability of many of our codes to
the numerical analysis community. The details are below.

Our codes and Web sites should be in place by Tuesday October 3rd.

The commercial version of HSL 2000 will be launched by AEA Technology
on October 16th.

HSL 2000

HSL (formerly the Harwell Subroutine Library) is a collection of ISO
Fortran codes for large scale scientific computation written by
members of the Numerical Analysis Group at Rutherford Appleton
Laboratory and by other experts and collaborators. As the Library
has evolved, many of the older packages have been superseded by
newer versions, with increases in functionality, improved
interfaces, or speed of execution. From October 2000, HSL will be
divided into two parts, the main library, HSL 2000; and an archive,
HSL Archive. The HSL Archive comprises packages that have either
been superseded by more modern codes, or that we no longer feel able
to support. Many new packages are to be introduced as part of the
release of HSL 2000. These include new sparse matrix and
optimization codes and new codes for use on parallel computers.

Free use of HSL 2000 by UK academics

While HSL 2000 continues to be a commercial product, it is now
freely available for UK academics (those whose email address ends in, and who access the codes from a machine) for academic
research or teaching purposes. This innovation is a direct result of
much of the core funding for the Group being provided by a grant
from EPSRC (GR/M78502).

Free academic use of HSL Archive by everyone

In addition, the HSL Archive is now freely available to anyone (UK
and elsewhere), so long as the codes are not then incorporated into
a commercial product; no support is associated with free access to
the HSL Archive.

How to access the codes

Access is by way of the HSL WWW page

Access to both HSL 2000 (for and the HSL Archive are by
means of short-lived individual password-controlled accounts.
Potential users are asked for brief details of the use they intend
to make of the package(s) they aim to download. Users are also
asked to accept a conditions-of-use form, and are not permitted to
divulge their userid and password to anyone else, nor to distribute
any codes they obtain to a third party.

Information on the commercial use of HSL 2000 can be found by links
from the above Web page.
