Chebfun is an open-source MATLAB package hosted on GitHub for numerical computing with functions in 1D and 2D. It is also a powerful and convenient tool for numerical solution of ODE initial- and boundary-value problems, as well as certain time-dependent PDEs in 1D, and a book about solution of ODEs in Chebfun is in preparation. New features in V5.3 include: - QUIVER for phase plane plots of chebops defining ODEs - FOLLOWPATH for pseudo-arclength continuation - Simplifications of ODE and PDE syntax - Faster algorithms for ODEs and PDEs - Redesign of chebfun constructor and removal of "epslevel" - EXPLAIN for a movie explaining low-rank chebfun2 construction - 'TURBO' for Chebyshev coefficients below the usual 1e-16 - PLOTREGION for estimated ellipses and strips of analyticity - Fast disrete Legendre transforms (LEGCOEFFS2LEGVALS etc.) Details of these and other new features are in the release notes at http://www.chebfun.org. In 2016 we expect to release Chebfun3 for computation in 3D, SPHEREFUN for computation on spheres, and SPIN for fast solution of KdV and other stiff PDEs. ------------------------------------------------------- From: Pavel Solin [log in to unmask] Date: November 29, 2015 Subject: European Seminar on Computing, Czech Republic, Jun 2016 DEADLINE APPROACHING - ESCO 2016 http://esco2016.femhub.com This is a friendly reminder that the deadline to submit an abstract to the Fifth European Seminar on Computing (ESCO 2016) is December 15, 2015.

Sergeyev [log in to unmask] Date: November 30, 2015 Subject: Numerical Computations: Theory and Algorithms, Italy, Jun 2016 Numerical Computations: Theory and Algorithms http://si.deis.unical.it/~yaro/numta2016 The 2nd International Conference and Summer School NUMTA2016 19-25 June 2016, Club Med Resort Napitia, Pizzo Calabro, Italy THE GOAL of NUMTA2016 Conference is to create a multidisciplinary round table for an open discussion on numerical modeling by using traditional and emerging computational paradigms. The Conference will discuss all aspects of numerical computations and modeling from foundations and philosophy to advanced numerical techniques. New technological challenges and fundamental ideas from theoretical computer science, linguistic, logic, set theory, and philosophy will meet requirements and new fresh applications from physics, chemistry, biology, and economy. Researchers from both theoretical and applied sciences are very welcome to submit their papers. Submissions discussing new computational paradigms, relations with foundations of mathematics, and their impact on natural sciences are particularly solicited. A special attention will be dedicated to numerical optimization and different issues related to theory and practice of the usage of infinities and infinitesimals in numerical computations. SUMMER SCHOOL offering tutorials and discussion sections covering the topics of the Conference there will be organized. Participants at the Summer School can submit either regular papers or participate at the poster session. English is the working language both at the Conference and the Summer School. YOUNG RESEARCHER AWARD (500 Euro and the Award certificate) for the best presentation made by a young scientist will be awarded during the conference.
