What’s New in MATLAB R2017a?
MATLAB R2017a was released last week. Many of the changes reported in the release notes are evolutionary, building on and extending major new features introduced previously. For example, the Live Editor continues to gain expanded capabilities. In this post I … Continue reading
Tracing the Early History of MATLAB Through SIAM News
A recent blog post by Ned Gulley points out that the new mathematics gallery (“Mathematics: The Winton Gallery”) at the Science Museum, London, contains a copy of the disk and manual for MATLAB 1.3, from 1985, sitting next to a … Continue reading
Parallel Numerical Linear Algebra for Extreme Scale Systems
A minisymposium Parallel Numerical Linear Algebra for Extreme Scale Systems was held at the SIAM Conference on Computational Science and Engineering, Atlanta on February 28, 2017. Today’s most powerful supercomputers are composed of hundreds of thousands of computing cores (CPUs … Continue reading
Writing Mathematics in Pencil, and Why Analogue is Not Dead
It’s an old joke that mathematicians need just a pencil, paper, and a bin, while philosophers are even more frugal because they don’t need the bin. Yet nowadays more and more of the time of mathematicians, indeed all scientists, is … Continue reading
PCAM Authors Speaking About Their Work at SAMSI
The Statistical and Applied Mathematical Sciences Institute (SAMSI) has just run a Workshop on the Interface of Statistics and Optimization. Among the speakers were four authors of articles in The Princeton Companion to Applied Mathematics (PCAM). In an earlier post … Continue reading
Preparing CMYK Figures for Book Printing
All printing is done in CMYK, the color space based on the four colors cyan, magenta, yellow, and black. Figures that we generate in MATLAB and other systems are invariably saved in RGB format (red, green, blue). When we send … Continue reading
Good Times in MATLAB: How to Typeset the Multiplication Symbol
The MATLAB output >> A = rand(2); whos Name Size Bytes Class Attributes A 2×2 32 double will be familiar to seasoned users. Consider this, however, from MATLAB R2016b: >> s = string({‘One’,’Two’}) s = 1×2 string array “One” “Two” … Continue reading
Hyphenation of Compound Words
Compound words are common in mathematical writing and it can be hard to remember how to hyphenate them. Unfortunately, there are no hard and fast rules. In this article I give some guidance and illustrative examples. The principle to keep … Continue reading
