I have just completed a wonderful trip, a two-week lecture tour of eight universities in five cities in China. I was accompanied on the trip by David Chen from the MathWorks office in Shanghai and Cecilia Liu from our Beijing office. We made a side trip to the Giant Panda Conservation Research Base, in Chengdu, Sichuan Province, central China, where we had an opportunity to meet this fellow, who is not a MATLAB user.... 続きを読む >>

Chebfun revives a classic video game, with a few mathematical twists (literally)... 続きを読む >>

The ROOTS function in Chebfun is one of its most powerful features. This is the second part of my series on Chebfun. Part one is here. ... 続きを読む >>

I recently attended "Chebfun and Beyond", a three-day workshop in Oxford, England. Chebfun is a mathematical research and open source software project for numerical computing with functions. I plan to write a series of Cleve's Corner blog posts about Chebfun. ... 続きを読む >>

The Game of Life, including the infinitely expanding universe, is a gorgeous application of MATLAB sparse matrices.... 続きを読む >>

This is part one of a series of posts about John Conway's Game of Life. One deceptively simple rule leads to an incredible variety of patterns, puzzles, and unsolved mathematical problems, and a beautiful use of MATLAB sparse matrices. ... 続きを読む >>
