The first posting earlier today was truncated. Here is the complete post. Even though I am one of the founders of the MathWorks, I only acted as an advisor to the company for its first five years. During that time, from 1985 to 1989, I was trying my luck with two Silicon Valley computer startup companies. Both enterprises failed as businesses, but the experience taught me a great deal about the computer industry, and influenced how I viewed the eventual development of MATLAB. This post continues the discussion of the Intel Personal Supercomputer... read more >>

Complex step differentiation is a technique that employs complex arithmetic to obtain the numerical value of the first derivative of a real valued analytic function of a real variable, avoiding the loss of precision inherent in traditional finite differences.... read more >>

The Lambert W function deserves to be better known. It pops up in all sorts of places. And our MATLAB function for evaluating the function is a beautiful use of the Halley method.... read more >>

By reaching 33.86 petaflops on the LINPACK Benchmark, China's Tianhe-2 supercomputer has just become the world's fastest computer. The technical computing community thinks of LINPACK not as a matrix software library, but as a benchmark. In that role LINPACK has some attractive aspects, but also some undesirable features.... read more >>

Nick Trefethen has framed the original flip chart that I described in my Lake Arrowhead Coauthor Graph blog earlier this week and has it on the wall of his office at Oxford University. His colleage Nick Hale has taken these photos. (The faded name in the cell at the lower left just northwest of mine is Tony Chan.)... read more >>

In my previous blog post I reprinted the Cleve's Corner article from the 1995 issues of MATLAB News and Notes and SIAM News about the Pentium division bug. In today's post I would like to describe some of the effects that affair had on the emerging Internet, the MathWorks, and the Intel Corporation,... read more >>
