I have a minor question regarding the syntax highlighting in math
mode
that has been bugging me for a while. I was wondering if anyone can
help me with that. Here it is,
AUCTeX sometimes color the caret (^) and the underscore (_) red in
math mode (which should normally be orange). I could not find the
reason of this behavior. For example look at the attached two
screenshots, they are both from one document, in one of them
everything is orange, and in the other one the caret and underscore
signs are red.
I use “align” environment for my equations.
Hi Kourosh,
I can't reproduce what you're describing. This is how your examples
look for me. N.B. I don't use any themes or any customization to
AUCTeX
fonts:
Maybe you disable any themes (if any) and try it again. For the next
time, please also send some code which can be copy&pasted; it is
tedious
to type code. Here the code I used:
--8<---------------cut here---------------start------------->8---
\documentclass[10pt]{article}
\usepackage{amsmath}
\begin{document}
\begin{align}
\label{eq:1}
\Phi(\lambda_1, \lambda_2, \lambda_3) = \sum_{n=1}^N
\frac{\mu_n}{\alpha_n} (\lambda_1 ^ {\alpha_n} + \lambda_2 ^
{\alpha_n} + \lambda_3 ^ {\alpha_n} -3),
\end{align}
increment $t$,
\begin{align}
\label{eq:2}
\matr{\ddot{u}} |_{(t)} = \matr{M} ^ {-1 \cdot (\matr{P} - \matr{I})
|_{(t)}}.
\end{align}
\end{document}
--8<---------------cut here---------------end--------------->8---
Best, Arash
