I am trying to generate latex output as given below.
However, the types is not coming properly aligned. It looks like it subscribes to the previous array environment. Could you please point out the error?
My code is as follows -
\documentclass{article}
\usepackage{amssymb,amsmath}
\def \R {\mathbb{R}}
\begin{document}
\begin{equation}
M_2=\left\{
\begin{array}{r}
variables : \left\{ \begin{array}{r}
inputs : x \\
outputs : y
\end{array}
\right.\\
types : x,y \in \R \\
behaviors : y = e^x \\
\end{array}
\right.
\end{equation}
\end{document}
