Subject: New ODE Solvers Available
The ordinary differential equation (ODE) solvers VODE and VODPK can be
obtained from netlib in both single and double precision Fortran. The
solvers feature backward differentiation (BDF) methods for stiff ODEs
and implicit Adams methods for non-stiff ODEs. They combine features
of the earlier codes EPISODE and LSODE and have a calling sequence
very similar to LSODE and LSODPK, respectively. Both use a
fixed-leading coefficient version of the variable step BDF and Adams
methods. VODE uses LU factorization, allows banded and dense
Jacobians, and has an option that lets the user keep a copy of the
full Jacobian matrix, as well as the LU factored Newton matrix. For
many problems this can increase performance considerably. VODPK uses
a preconditioned Krylov method for the numerical linear algebra. The
packages documentation in the preamble, and examples of use.
These codes may be obtained free of charge as follows:
send mail to netlib@research.att.com
with the message:
send vode.f from ode to obtain double precision VODE
send svode.f from ode to obtain single precision VODE
send vodpk.f from ode to obtain double precision VODPK
send svodpk.f from ode to obtain single precision VODPK
These codes make use of LINPACK and the Basic Linear Algebra
Subroutines (BLAS), and the machine constant routines R1MACH/D1MACH,
which must be obtained separately from netlib or from some other
source .

Subject: Wavelets Mailing List
We are happy to announce you a
W A V E L E T D I G E S T.
Nowadays, wavelets are one of the most rapidly developing research areas
both in pure/applied mathematics and signal/image processing.
More and more people are becoming interested in using wavelets
for a broad spectrum of applications.
For researchers it is essential to stay informed on the latest
developments. Hence we are planning, here at the University of
South Carolina, to start an edited "wavelet digest."
Topics we would like to cover in our digest are:
- Announcements of:
- future wavelet conferences, call for papers, etc.
- talks on wavelets
- wavelet courses
- new preprints (and how to get them, e.g. by ftp)
- wavelet articles appearing in journals
- new books on wavelets
- wavelet-related job opportunities
- Questions (and answers) concerning:
- mathematical background of wavelets
- technical aspects of wavelets
- references
- addresses
- Regularly updated reference lists
- Reviews of recently published books on wavelets
- Posting of open problems
- Available wavelet software, where and how to get it
If you would like to subscribe to this mailing list,
send a message with "subscribe" as the subject to
wavelet@math.scarolina.edu.
If you want to submit something to the digest,
send a message with "submit" as the subject to
wavelet@math.scarolina.edu.
Please pass this message on to others who you think might be interested.
We are hoping to present the first wavelet digest to you soon.

Subject: Matrix Inverse
I am looking for a reliable algorithm (/MATLAB function file) to invert
a very ill-conditioned 4x4 matrix. Two rows of the matrix have exponentially
large elements and rest have exponentially small elements. This matrix occurs
in certain fluid-structure interaction problems, where elements have physical
significance in terms of exponentially varying elastic and acoustic fields.
Thanking you in advance,
Ardhendu Pathak.

The format of the joint meeting will follow the pattern set by its
predecessors. It is intended to review hardware and architecture
developments together with languages and software tools for supporting
parallel processing and to highlight advances in models, algorithms and
applications software on vector and parallel architectures.
More than 230 papers written by authors from 35 countries have been
submitted for consideration to CONPAR 92-VAPP V. Among these papers,
the Program Committee has selected 36 full papers, 58 short papers
and several posters. Five invited presentations, four tutorials and
various exhibitions will complete the Conference. I am pleased to thank
the Program Committee Members and the 600 referees (each paper has been
evaluated by four referees), for their excellent job in building the
scientific content of the Conference.
