Lake Arrowhead Coauthor Graph Photos 1

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.)... 더 읽어보기 >>

Pentium Division Bug Affair

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,... 더 읽어보기 >>

Pentium Division Bug Revisited 3

The Pentium division bug episode in the fall of 1994 was a defining moment for the MathWorks, for the Internet, for Intel Corporation, and for me personally. In this blog I am reprinting the article that I wrote for the Winter 1995 issue of MATLAB News and Notes and for SIAM News. In my next blog I want to discuss the episode's impact.... 더 읽어보기 >>

Wilkinson’s Matrices

One of Jim Wilkinson's outstanding skills was his ability to pick great examples. A previous post featured his signature polynomial. This post features his signature matrices.... 더 읽어보기 >>

Jim Wilkinson 4

I have already made several posts about gatlin, the image distributed with MATLAB of the organizing committee for the Gatlinburg III conference. From the MATLAB point of view, the first man on the left in the photo, J. H. Wilkinson, is by far the most important. From the early days of computers in the 1950s until his death in 1986, Wilkinson was the world's authority on matrix computation. His research on eigenvalue algorithms and their implementation in Algol led directly to EISPACK, the mathematical foundation for the first MATLAB.... 더 읽어보기 >>
