Serra House was built in 1923 to be the retirement home for President David Starr Jordan. By the late 1970's it had been assigned to the Computer Science Department and housed the Numerical Analysis group. Professors George Forsythe and Gene Golub had their offices there at one time or another, as did various grad students, post docs, and visitors.<\/p>\r\n<p>There was a lovely patio, a volleyball court and a real feeling of camaraderie in the Serra House group. In the academic year 1978\/79 a particularly strong group of grad studies were working in Serra House. Nick Trefethen was one of them. Marsha Berger, Michael Overton and Randy LeVeque were others.<\/p>\r\n<p>In 1978\/79 Gene Golub was away from Stanford on sabbatical and I took his place for the year. I taught the graduate numerical analysis course and used my new Fortran <a href=\"https:\/\/dl.acm.org\/doi\/pdf\/10.1145\/3386331\" target=\"_blank\" rel=\"noopener\">\"matrix laboratory\"<\/a>. It was just a primitive matrix calculator. It was not impressive numerical analysis nor impressive computer science.<\/p>\r\n<p>Nick and Randy were enrolled in that course and Marsha and Michael sat in sometimes. This was their first exposure to MATLAB. It would have to become a more mature tool before they would find it useful. A few grad students from engineering also took my course and found that primitive MATLAB useful for work in areas like control theory and signal processing, areas that I knew nothing about at the time. That eventually led to Jack Little and to MathWorks.<\/p>\r\n<h4>Nick<a name=\"a4a013d8-522b-4ae7-b868-6f98489858b7\"><\/a>\r\n<\/h4>\r\n<p>\r\n<img decoding=\"async\" vspace=\"5\" hspace=\"5\" src=\"https:\/\/blogs.mathworks.com\/cleve\/files\/Nick_Lino.png\" alt=\"\"> <\/p>\r\n<p>\r\n<a href=\"https:\/\/www.henkvandervorst.nl\/computing.html\" target=\"_blank\" rel=\"noopener\">https:\/\/www.henkvandervorst.nl\/computing.html<\/a>\r\n<\/p>\r\n<p>Linocut by Henk van der Vorst.<\/p>\r\n<p>Nick is a renowned scholar of computational mathematics.
