Someone asked about the architecture of LaTeX. After avoiding the question for a day, I decided to answer. Since it’s possible the question will be closed and possibly deleted, I figured I’d reproduce the relevant portion of my answer here…. Continue Reading →
I have two versions of my cv: one for public consumption and one which contains extra private bibliography entries for work that is in submission. Obviously these are mostly the same so I had one one that had a \newif\ifpublic… Continue Reading →
On occasion, one has cause to compare two boxes and compute the maximum of the two widths. If the two boxes are 0 and 2, then the standard way to do that is something like \ifdim\wd0>\wd2 \dimen0 \wd0 \else \dimen0… Continue Reading →
This post provides a guide to getting started with Beamer, a popular LaTeX package for preparing slide presentations. The post: (a) Lists some of the benefits of Beamer in comparison to PowerPoint; (b) Links to tutorials and suggestions for learning… Continue Reading →
For those who don’t already know, Beamer is a useful package in LaTeX for preparing slide presentations. I have a Beamer template of preamble and slide templates. I found having a template was useful: (a) when first learning Beamer commands,… Continue Reading →
The code should be self-explaning.. function y = f(x) y1 = x.* (x<0); y2 = x.^2 .* (x>=0) .* (x<2); y3 = 4 .* (x>=2); y = y1 + y2 + y3;
