I have just returned from the huge Supercomputing 2012 conference in Salt Lake City. I can report on interesting reactions to some questions I posed in last week's blog and on some impressive speedup results when we ran the code in last week's blog on a parallel cluster in the Cloud.... read more >>

We know a little bit, but not much, about the linear algebraic properties of magic squares. ... read more >>

With origins in centuries old recreational mathematics, magic squares demonstrate MATLAB array operations. ... read more >>

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.... read more >>
