Hi Nuri,
I understand that you want to insert a marix/vector with curly braces in MATLAB live editor text. The simplest way would be to use LaTeX equation. The following snippet creates the vector as requested in the example
\left\lbrace \begin{array}{c}
a \\
b \\
c
\end{array}\right\rbrace$
You can try any of the following pair instead of lbrace and rbrace:
- \lbrack - \rbrack
- \lbrace - \rbrace
- \langle - \rangle
- \lvert - \lvert
- \lVert - \lVert
