## Using harpoon vector symbol in LaTeX

My favorite vector symbol is a harpoon, but the harpoon package defaults to text mode, which will fail when math characters like \ell are used in the math mode. To fix this, in your document header put: \usepackage{harpoon} \newcommand*{\vect}[1]{\overrightharp{\ensuremath{#1}}} then $\vect{d\ell}$ will work. reference: http://tex.stackexchange.com/questions/66723/nudging-overset-characters-downwards

## IEEEtran.cls prerequisities

You can invoke the IEEEtran.cls by starting your .tex file with: \documentclass[10pt]{IEEEtran} You may get an error stating that IEEEtran.cls not found. In that case, do: sudo apt-get install texlive-publishers texlive-fonts-recommended biblatex so that you don’t get a Font OT1/ptm/m/n/10=ptmr7t at 10.0pt not loadable error.
