New version of Octave’s ODE and DAE solvers released

Jacopo has released odepkg 0.85 for Octave. This is a compatibility release to prepare odepkg for the upcoming Octave 4.0. The next major release of odepkg (possibly 0.9 or even 1.0?) will require Octave 4.1 because functions like odeget, odeset and some standard time steppers (ode45,…) will be moved into Octave core soon. Odepkg will then focus on specialized methods that are not available in Matlab as e.g. RADAU5. Further Discussion is found on the mailing list.

Book “Progress in Differential-Algebraic Equations” is online

IMG_3067.JPG The book “Progress in Differential-Algebraic Equations” is available online and has just been published on SpringerLink:

This book contains the proceedings of the 8th Workshop on Coupled Descriptor Systems held March 2013 in the Castle of Eringerfeld, Geseke in the neighborhood of Paderborn, Germany. It examines the wide range of current research topics in descriptor systems, including mathematical modeling, index analysis, wellposedness of problems, stiffness and different time-scales, cosimulation and splitting methods and convergence analysis. In addition, the book also presents applications from the automotive and circuit industries that show that descriptor systems provide challenging problems from the point of view of both theory and practice.

The book contains nine papers and is organized into three parts: control, simulation, and model order reduction. It will serve as an ideal resource for applied mathematicians and engineers, in particular those from mechanics and electromagnetics, who work with coupled differential equations.
