Best Answer

You can simply reduce your subfigures to .47\textwidth and insert something like

{\LARGE$\xrightarrow{T}$}

between them.

MWE:

\documentclass{article}
\usepackage{float,subcaption}
\usepackage[demo]{graphicx}
\usepackage{amsmath}
\begin{document}
\begin{figure}[H]
\centering
\begin{subfigure}{.47\textwidth}
  \centering
  \includegraphics[width=.7\linewidth]{2D/cc1.png}
  \caption{Original Matrix, $A$}
\end{subfigure}%
{\LARGE$\xrightarrow{T}$}%
\begin{subfigure}{.47\textwidth}
  \centering
  \includegraphics[width=.7\linewidth]{2D/cc2.png}
  \caption{Jordan Canonical Form of Matrix, $A$}
\end{subfigure}
\caption{Changing Coordinates}
\end{figure}
\end{document}
