Subject: Cleve Moler
With Cleve Moler’s passing, we share a profound loss for our field
and for all of us who had the privilege of knowing him. Cleve was,
in every sense, a gentle giant: brilliant, generous, thoughtful,
and kind. He was not only a towering figure in numerical computing
but also a trusted colleague and a dear friend.
His contributions to scientific and numerical computing were
extraordinary.
Through MATLAB, Cleve changed the way generations of scientists,
engineers, mathematicians, and students think about computation,
experimentation, modeling, and problem solving. He helped make
numerical methods accessible, interactive, and practical. What had
once required specialized programming, considerable effort, and
deep knowledge of computing systems could suddenly be explored
directly and intuitively. In doing so, Cleve gave an entire
community a new language for discovery.
The impact of his work is difficult to overstate. MATLAB became
part of the daily practice of countless people across academia,
industry, and education. It shaped how students learned linear
algebra, how engineers designed systems, how scientists tested
ideas, and how researchers turned mathematical concepts into
working computational tools. Cleve’s influence reached far beyond
any single discipline. His work touched nearly every area where
computation and mathematics meet.
But Cleve’s legacy is not only in software, algorithms, or
institutions. It is also in the people he encouraged, challenged,
and inspired. He was a colleague, mentor, and friend to many. He
could ask a pointed question that went directly to the heart of a
matter, but always with curiosity, humor, and goodwill. Those of us
who saw him at conferences will remember that unmistakable booming
voice, his careful attention to the technical details, and the warm
smile that so often followed.
Cleve represented the best of our community: intellectual depth,
practical insight, humility, and humanity. He helped build the
foundations on which much of modern computational science rests,
yet he remained approachable, generous, and deeply engaged with
others.
He leaves behind a remarkable legacy, one that will continue
through the tools he created, the ideas he advanced, the company he
helped build, and the many people whose work and lives he
influenced. We will miss his wisdom, his questions, his presence,
and his insight.
We miss our friend.

Subject: New book, Finite Element Methods for Eigenvalue Problems, 2nd Ed.
Finite Element Methods for Eigenvalue Problems by J. Sun and A. Zhou covers
finite element methods for several typical eigenvalue problems that arise from
science and engineering. Both theory and implementation are discussed in
depth at the graduate level. The background for these problems is included
along with functional analysis tools, finite element discretization methods,
convergence analysis, techniques for matrix eigenvalue problems, and
computer implementation. The second edition adds two new chapters on the
quad-curl eigenvalue problem and scattering resonances and incorporates
extensive revisions and updated references throughout.

Subject: Workshop on Optimal Control of Dynamical Systems and Applications, Croatia, May 10-13, 2027
We are very pleased to announce that the 5th Workshop on Optimal Control of
Dynamical Systems and Applications will be held from 10th to 13th of May 2027
in the picturesque resort Seaside Camping Resort Mon Perin, located on the
Adriatic coast in the region of Istria in Croatia (around 30km north of the city of
Pula). The workshop is organized by the School of Applied Mathematics and
Informatics, University of Osijek, Croatia. More details can be found on the main
webpage of the event: https://indico.mathos.hr/event/18/
The workshop continues the one-decade-old tradition of workshops, previously
organized in Opatija (2016), Osijek (2018 & 2022), and Villány (2025). The main
topics include, but are not limited to, the following: optimal control of dynamical
systems, model order reduction methods, optimization, numerical linear algebra,
and their applications in the analysis and simulation of dynamical systems.
Plenary lectures will be given by Prof. Dr. Carmen Gräßle from TU Braunschweig,
Germany, Prof. Dr. Luka Grubišić from the University of Zagreb, Croatia, and Jun.-
Prof. Dr. Manuel Schaller from TU Chemnitz, Germany.
