These are two useful LaTeX macros for creating equality-at and (the more general) relation-at signs. These macros depend on the mathtools package. As with all other macros you should add them to you preamble in order to use.
The general macro is the \relat. It takes two arguments, the relation and an expression where the relation takes place (the “at”). The equality-at macro, \eqat is a specific case of \relat. I’ve created it because it is commonly used and only requires passing the “at” argument.

Recently I’ve worked on a Hebrew document in LaTeX and wanted to use the split environment to typeset some multiline formula. The document which compiled just fine till that point, failed to compile with the following error:
Package amsmath Error: \begin{split} won't work here. Read the rest of this entry »

When writing a document that contains mathematics, many time the need to add an explanation (e.g. stating the theorem used) is raised. To answer this need I wrote two short LaTeX macros: \explain and \explainup.

Few days ago I finally decided to install Ivritex-1.2.1 on my system. I’m running a tetex-3.0. The new version of Ivritex includes some very important improvements and, at least for me, the most important thing is support for the Culmus fonts. tetex-3.0 introduced a major directory change which cause many problem with installing packages which are unaware of the changes. In this post I will try to walk through the installation process.
TEXMF will be the directory of you local TeX tree (usually /usr/share/texmf). Before Begining the installation process make sure you have the Culmus fonts installed. Apparently Culmus is not optional it’s a requirement. I’ll assume that your Culmus fonts are installed in /usr/share/fonts/culmus.
- Download the ivritex-1.2.1 source-code from here .
- Extract the archive into a temporary directory.
- Save the diff file below a file named “Makefile_patch” and save it inside ivritex-1.2.1/fonts/culmus .
- Apply the patch by going to the ivritex-1.2.1/fonts/culmus directory (under the directory where you extracted the source archive) and executing “patch Makefile_patch. The patch will alter the places where some file will be installed.
- As root execute “updmap –enable Map culmus.map”.
- Still as root execute “mktexlsr”.
- Ivritex 1.2.1 should be installed now.

If you ever wrote a document in latex (or tex) that used inline formulas you know how frustrating it is when latex insists on breaking you inline formula across two lines. The easiest solution to this problem, in my opinion is to prevent line breaking inline formulas at all except under extreme cases. To prevent line breaking inline formulas just add the following two lines into your preamble:
\relpenalty=9999
\binoppenalty=9999
Now I will explain what we did. \relpenalty=[number parameter] the parameter specifies the penalty for breaking a math formula after a relation when the formula appears in a paragraph. Plain TEX sets \relpenalty to 500. \binoppenalty=[number parameter] the parameter specifies the penalty for breaking a math formula after a binary operator when the formula appears in a paragraph. Plain TEX sets \binoppenalty to 700. Both parameters can be set anywhere from 0 to 10000. If set to 10000 the inline formulas will never break even in extreme cases. Setting it a bit lower would prevent line breaking except where tex would encounter extreme cases which must have a line break because of the situation.

This guide is base on a guide published by Dekel Tsur that can be found here. Dekel Tsur’s guide was very good but now it is outdated since it doesn’t work with teTex 3.0. In this guide I addressed this issue and updated the instructions and scripts so it will work with teTex 3.0.Since the quality of the Hebrew metafonts that comes with the Hebrew LaTeX is quite poor, alternative fonts are needed. The best quality free Hebrew fonts are TrueType fonts (for example, the times new/arial/courier new fonts). Using TrueType fonts with TeX is somewhat complicated, but it is quite easy with pdfTeX, as pdfTeX has native support for TrueType fonts. This document explains how to use TrueType fonts with pdfTeX. Since Hebrew requires the use of the eTeX engine, you need to have the pdfelatex program. It is available in teTeX 1.0 (which comes with recent Linux distributions). The instruction below allows using nikud, although the result is quite poor as the nikud glyphs are not aligned correctly (but it is better than nothing).
