Let me give a fully general answer, in case others need this information too.

If you have MaTeX 1.6.1 or earlier (which does not use paclets), it is located in FileNameJoin[{$UserBaseDirectory, "Applications"}]. Navigate to that directory and delete the MaTeX directory within.

If you have MaTeX 1.6.2 or later, it uses the paclet system. It is not strictly necessary to uninstall earlier versions when upgrading. <<MaTeX` will always load the newest version that is installed.

To see which versions you have installed, use the command

versions = PacletFind["MaTeX"]

To uninstall a specific version, apply PacletUninstall to it. For example, to uninstall the second element returned in the versions list above, use

PacletUninstall[ versions[[2]] ]

To uninstall all versions of MaTeX at the same time, use

PacletUninstall["MaTeX"]

I do not usually delete the files in ~/Library/Mathematica/Paclets/ manually. I believe it is better to let the paclet manager do it.

Some of this information is available at the following locations:

• https://mathematica.stackexchange.com/questions/141887/how-can-i-install-packages-distributed-as-paclet-files/
• https://github.com/szhorvat/MaTeX

Version 1.6.2 is now released. Get it from the GitHub releases page.

The 1.6 series can compile a list of expressions using a single call to LaTeX, which is much faster than compiling them separately.

In 1.6.2 now the documentation integrates with Mathematica. Search for "matex" in the documentation center.

This release is distributed as a .paclet file. This means that the installation instructions have changed. Please see the README on GitHub. This is my first experiment with this distribution format, so any feedback is appreciated.

Hi Gianluca,

You are right that in this case the output is almost identical, and Mathematica's math typesetting is pretty good, even if it lags behind that of LaTeX. LaTeX is of course the very best, and Mathematica is also very good compared to similar alternatives. A while ago I would not have written this package, it would have seemed like wasted time since Mathematica's typsetting should be at least good enough for most purposes ... However, the reality is that (1) I do not always set the standards myself, unfortunately, so in the past I was forced to add LaTeX-made labels in drawing programs sometimes ... (2) it's not always easy to type formulae in Mathematica; right now I type them in a text cell after pressing Ctrl-9 to start a math subcell, then copy them; otherwise the spacing around operators is not always correct (3) math symbols won't use the Latin Modern font, try e.g. "\!\(\*FormBox[\(\(\[ScriptCapitalN](x)\)~\(\[ScriptCapitalG](x)\)\), TraditionalForm]\)" (I haven't tried Latin Modern Math though!) (4) Mathematica occasionally has bugs, e.g. this in v10.0.2. Typesetting quality also tends to be affected when exporting to PDF.

My point is simply that the package grew out of a real practical need. I wanted to say this because a couple of years ago I may have considered this a useless exercise that won't add much to what Mathematica can already do.

I hope others will find it useful too!

I should also mention the MathPSFrag package which achieves similar results using PSFrag. I only discovered this after writing MaTeX ... yes, I should have googled first, not afterwards :-) I haven't tried using this package yet, so I can't comment on which is the most convenient approach.

Szabolcs, it looks great. Thanks for sharing!
