From: Nick Trefethen [log in to unmask]
Date: November 27, 2015
Subject: Chebfun V5.3 release

The Chebfun team is pleased to announce the release of Chebfun V5.3 at  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  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.

Numerical Computations: Theory and Algorithms
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
