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 >>

1994年秋天的奔腾分区的错误发作是数学，互联网，英特尔公司和我个人的决定性时刻。在此博客中，我正在重印我在1995年冬季发行的Matlab新闻和笔记以及Siam News的文章。在我的下一个博客中，我想讨论这一集的影响。read more >>

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....read more >>

The Quantum Matrix Processor, being announced today, is the world's first viable quantum array processor. Basic matrix operations are done instantaneously, with infinite procession. The programming environment is classic MATLAB....read more >>

Wilkinson's polynomials are a family of polynmials with deceptively sensitive roots....read more >>

I have already made several posts aboutgatlin，该图像与加特林堡III会议组织委员会的MATLAB分发。从MATLAB的角度来看，照片中左侧的第一个人J. H. Wilkinson是迄今为止最重要的。从1950年代的计算机早期到1986年他去世，威尔金森（Wilkinson）是矩阵计算的世界权威。他对特征值算法及其在阿尔戈尔的实施的研究直接导致了第一个MATLAB的数学基础Eispack。read more >>

逆希尔伯特矩阵，Invhilb, has recently made surprise appearances in科迪, the programming game on MATLAB Central, andone of Ned's posts在里面MATLAB Spoken Hereblog. Inverse Hilbert matrices had nearly been forgotten in MATLAB. Their comeback is due to the sign pattern of their entries. But I want to take you back to their original role demonstrating ill conditioning in numerical calculation....read more >>
