I want to use a matrix environment that is included in an outer
environment, so:
```
Environment:
\begin{equation*}
\left|
\begin{matrix}
a_1 & b_1\\
a_2 & b_2
\end{matrix}
\right|
\end{equation*}
Display--math:
\[
\left|
\begin{matrix}
a_1 & b_1\\
a_2 & b_2
\end{matrix}
\right|
\]
Inline--math:
\(
\left|
\begin{matrix}
a_1 & b_1\\
a_2 & b_2
\end{matrix}
\right|
\)
```
But for the second and third cases (display-math and inline-math) the
preview and export to latex are failed:
exported LaTeX:
```
Environment:
\begin{equation*}
\left|
\begin{matrix}
a_1 & b_1\\
a_2 & b_2
\end{matrix}
\right|
\end{equation*}
Display--math:
$\backslash$[
\left|
\begin{matrix}
a_1 & b_1\\
a_2 & b_2
\end{matrix}
\right|
$\backslash$]
Inline--math:
$\backslash$(
\left|
\begin{matrix}
a_1 & b_1\\
a_2 & b_2
\end{matrix}
\right|
$\backslash$)
\end{document}
```
org-mode preview:

This is not a bug. \[...\] and \(...\) are inline elements within
a paragraph. However, \begin{...}...\end{...} environments are blocks,
and they break paragraphs. IOW, you cannot nest them.
The following should work however
\(
\left|\begin{matrix}
a_1 & b_1\\
a_2 & b_2
\end{matrix}\right|
\)
because \begin{matrix} doesn't start the line, and therefore is not seen
as starting a new LaTeX block.
As a rule of thumb, Org has limited support for raw LaTeX in a document.
This is not AucTeX. For specific needs, you may want to use LaTeX
blocks, i.e., #+begin_export latex...
Regards,
