In the example shown below for the image attached, how can I manipulate the code to get the rows labeled?

\begin{figure}
    \centering
    \subfloat[][]
    {\includegraphics[width=.3\textwidth]{10t10w125x300y3}} \quad
    \subfloat[][]
    {\includegraphics[width=.3\textwidth]{10t40w250x400y3}} \quad
    \subfloat[][]
    {\includegraphics[width=.3\textwidth]{10t100w340x500y3}} \\
    \subfloat[][]
    {\includegraphics[width=.3\textwidth]{30t10w200x400y3}} \quad
    \subfloat[][]
    {\includegraphics[width=.3\textwidth]{30t40w350x750y3}} \quad
    \subfloat[][]
    {\includegraphics[width=.3\textwidth]{30t100w550x1200y3}} \\
    \subfloat[][]
    {\includegraphics[width=.3\textwidth]{50t10w300x600y3}} \quad
    \subfloat[][]
    {\includegraphics[width=.3\textwidth]{50t40w600x1100y3}} \quad
    \subfloat[][]
    {\includegraphics[width=.3\textwidth]{50t100w600x1500y3}}
    \caption{Fields.}
    \label{subplots1310}
    \end{figure}

You forgot to mention what kind of label you want to use for the rows (a counter? some words?). In any case, one option is to use \parboxes for the labels on each row (using \raisebox you can further control the vertical alignment for these labels). Something like the following simple example:

\documentclass{article}
\usepackage[demo]{graphicx}
\usepackage{subfig}

\begin{document}

\begin{figure}
  \centering
  \raisebox{35pt}{\parbox[b]{.1\textwidth}{labelA}}%
  \subfloat[][]{\includegraphics[width=.28\textwidth]{10t10w125x300y3}}\hfill
  \subfloat[][]{\includegraphics[width=.28\textwidth]{10t40w250x400y3}}\hfill
  \subfloat[][]{\includegraphics[width=.28\textwidth]{10t100w340x500y3}}\par
  \raisebox{35pt}{\parbox[b]{.1\textwidth}{labelB}}%
  \subfloat[][]{\includegraphics[width=.28\textwidth]{30t10w200x400y3}}\hfill
  \subfloat[][]{\includegraphics[width=.28\textwidth]{30t40w350x750y3}}\hfill
  \subfloat[][]{\includegraphics[width=.28\textwidth]{30t100w550x1200y3}}\par
  \raisebox{35pt}{\parbox[b]{.1\textwidth}{labelC}}%
  \subfloat[][]{\includegraphics[width=.28\textwidth]{50t10w300x600y3}}\hfill
  \subfloat[][]{\includegraphics[width=.28\textwidth]{50t40w600x1100y3}}\hfill
  \subfloat[][]{\includegraphics[width=.28\textwidth]{50t100w600x1500y3}}
  \caption{Fields}
  \label{subplots1310}
\end{figure}

\end{document}

The result:

The demo option for graphicx simply replaces actual figures with black rectangles; do not use that option in your actual document.

I have mentioned it a few times before but IEEE does not directly use your .tex file. It's there to supply the bare minimal so if it looks like an article it's enough. It doesn't have to be following the standards internally.

They will recode your article with their own terrible terrible workflow, rasterize your images and ruin your math after acceptance. I've been using the following for a couple of years without any issues. It uses subcaption and does a superb job even though it has a command clash due to the redefinitions.

\documentclass[final]{ieeetran}
\usepackage{tikz,lipsum}
\usepackage[labelformat=simple]{subcaption}

% Training subcaption package to comply with
% IEEE standards. We can ignore the warning
% generated by caption.sty which is due to 
% the redefinition of \@makecaption
\DeclareCaptionLabelSeparator{periodspace}{.\quad}
\captionsetup{font=footnotesize,labelsep=periodspace,singlelinecheck=false}
\captionsetup[sub]{font=footnotesize,singlelinecheck=true}
\renewcommand\thesubfigure{(\alph{subfigure})}

\title{My title}
\author{my author}

\begin{document}
\maketitle
\begin{abstract}
\lipsum*[1]
\end{abstract}

\lipsum[2-5]
\begin{figure}
\begin{subfigure}[b]{.6\linewidth}
\centering%
\begin{tikzpicture}
\draw[help lines] (-1,-1) grid (1,2);
\end{tikzpicture}
\caption{A caption}
\label{fig:a}
\end{subfigure}%
\begin{subfigure}[b]{.4\linewidth}
\centering%
\begin{tikzpicture}
\draw[help lines] (-1,-1) grid (1,2);
\end{tikzpicture}
\caption{B cap}
\label{fig:b}
\end{subfigure}
\caption{Two figures.}\label{fig:1}
\end{figure}
\end{document}

If you only want the caption labels leave the sub \caption{} definitions empty and describe the subfigures in the main caption. If you want to remove also the (a),(b) use \phantomcaption commands as described in the manual.

[Tex/LaTex] how to make the same image size for 3×3 subplots

Measure the height of one of the images and use that on the rest.

\documentclass{article}
\usepackage{graphicx}
\usepackage{subfig}

\newlength{\common}

\begin{document}
\noindent\rule{\textwidth}{1pt}
\begin{figure}[htp]
\settoheight{\common}{\includegraphics[width=.3\textwidth]{example-image}}% get height
\subfloat[picture 1]{\includegraphics[width=.3\textwidth,height=\common]{example-image}}\hfill
\subfloat[picture 2]{\includegraphics[width=.3\textwidth,height=\common]{euclid-1.jpg}}\hfill
\subfloat[picture 3]{\includegraphics[width=.3\textwidth,height=\common]{images/supper.png}}
\end{figure}
\end{document}
