Subject: MORwiki: A Platform for Model Order Reduction

The MORwiki is a wiki including pages created for the research topic
of model order reduction (MOR). There are pages with descriptions of
MOR methods and a benchmark collection including deterministic,
parameterized systems, systems of first and second (differential)
order. Besides, there are pages introducing softwares for scientific
computing and MOR.

The purpose of MORwiki is to bring together researchers in the area of
MOR, as well as MOR users from application areas, and to provide a
platform for exchanging ideas and sharing benchmarks. MORwiki is
already public and is accessible via the link .

Everyone is welcome to contribute to the wiki by adding more MOR
methods and by uploading more benchmarks of systems such as PDEs,
DAEs, ODEs appealing for MOR. Please contact the responsible persons
of the MORwiki for permission.

Subject: Matlab Package for Planar BIE Solutions of Laplace's Equation

I have created a Matlab package for solving various boundary integral
equation (BIE) reformulations for Laplace’s equation in the plane. The
package covers both Dirichlet and Neumann boundary conditions. I
consider both interior and exterior problems; and the boundary can be
smooth, smooth with a single corner, or polygonal. We consider Nystrom
methods, collocation methods for piecewise polynomial approximations,
and a discrete spectral Galerkin method. The collocation method
includes the possibility of a graded mesh. The intent of the package
is to give a user the chance to experiment with different kinds of
numerical methods and different BIE reformulations.

The Matlab package for the programs and an accompanying manual can be
downloaded from

I would appreciate any comments and suggestions for improving this
package and this manual.

Subject: TIDES numerical ODE software version 2.0 released

We are pleased to announce the release of version 2.0 of TIDES
(Taylor Integrator for Differential EquationS).

TIDES is a free software to integrate numerically Ordinary
Differential Equations by using the Taylor Series method. This
software consists on a C (Fortran) library, libTIDES, and a
Mathematica package, MathTIDES.

TIDES version 2.0 is freely available under GNU General Public License
from the web page:

The main features of TIDES are the following:
- TIDES permits to integrate numerically ODE problems with
double and multiple precision (using MPFR and GMP libraries),
that means that you can solve ODE problems
up to any precision level in a reasonable computer time.
- TIDES may solve directly sensitivity equations with respect to
initial conditions or parameters up to any order.
- TIDES uses the Taylor Series method with an
optimized variable-stepsize and variable-order formulation,
and extended formulas for variational equations.
- The software has been designed to be extremely easy to use.
MathTIDES writes automatically the code in C (or Fortran).
- The derivatives and partial derivatives are obtained by using
Automatic Differentiation (AD) techniques.
- TIDES has dense output and it may detect events of ODEs.
