How to put matrix in picture environment

Question

I want to put matrix in Picture environment. I am trying this way \put(20,20){\begin{pmatrix}\end{pmatrix}} but it does not work. How can I put matrix in picture environment.

Answer 1

Maybe something as simple as putting the pmatrix in math mode via $ delimiters.

\documentclass{article}
\usepackage{amsmath}
\begin{document}
\fbox{\begin{picture}(100,100)
\put(40,40){Hi mom}
\put(20,20){$\begin{pmatrix}a&b\\c&d\end{pmatrix}$}
\end{picture}}
\end{document}
