\chapter{The basics}
\label{chap:introduction}
And so it begins ...

\section{A simple section}
\label{sec:asimplesection}
A citation \cite{Hofstadter1979}. Here is another citation \cite{Balakrishnan2013}.

\subsection{A sub-section}
\label{ssec:asubsection}
Some more text here.

\chapter{Figures, sub-figures and more}
\label{chap:figures}

A simple figure called \cref{fig:example_fig} is shown below.

\begin{figure}[!htbp]
\centering\includegraphics[width=0.5\textwidth]{fig}
\caption{Captions are also possible for figures.}
\label{fig:example_fig}
\end{figure}

\newpage

More complicated layouts of multiple figures using \texttt{subfloat} are also
possible as shown in \cref{fig:example_subfig}. Reference a subfigure directly
as \cref{subfig:subfig_1}.

\begin{figure}[!ht]
    \subfloat[ \label{subfig:subfig_1}]{%
     \includegraphics[width=0.3\textwidth]{small_fig}
   }
   \hfill
   \subfloat[ \label{subfig:subfig_2}]{%
     \includegraphics[width=0.3\textwidth]{small_fig}
   }
   \caption{A common caption is shown for both. Use (a) and (b) to refer to the
   subfigures.}
\label{fig:example_subfig}
\end{figure}

Finally, a full page of figures with a possible layout is shown in \cref{fig:full_page_fig}.

\begin{figure}[!htbp]
    \subfloat[]{ \includegraphics[width=0.4\textwidth]{small_fig} }
   \hfill
    \subfloat[]{ \includegraphics[width=0.4\textwidth]{small_fig} } \\
    \subfloat[]{ \includegraphics[width=0.4\textwidth]{small_fig} }
        \hfill
    \subfloat[]{ \includegraphics[width=0.4\textwidth]{small_fig} } \\
    \subfloat[]{ \includegraphics[width=0.4\textwidth]{small_fig} }
   \hfill
    \subfloat[]{ \includegraphics[width=0.4\textwidth]{small_fig} }\\
\caption{A full page of figures!}
\label{fig:full_page_fig}
\end{figure}

\chapter{Let's talk tables}
\label{chap:tables}

A simple table, with my personal tastes on borders and widths is shown below. 
\begin{table}[!htbp]
\begin{center}
\caption{Sequential modes in four-arm sinuous antennas.} 
\label{table:4sinuous_modes}
\def\arraystretch{1.5}
\begin{tabular}{|c | c | c | c | c |}
 \hline
Mode number & Port 1 & Port 2 & Port 3 & Port 4 \\
\hline
$M_{-2}$ & $0^\circ$ & $-180^\circ$ & $0^\circ$ & $-180^\circ$ \\ \hline
$M_{-1}$ & $0^\circ$ & $-90^\circ$ & $-180^\circ$ & $-270^\circ$ \\ \hline
$M_{+1}$ & $0^\circ$ & $90^\circ$ & $180^\circ$ & $270^\circ$ \\ \hline
$M_{+2}$ & $0^\circ$ & $180^\circ$ & $0^\circ$ & $180^\circ$ \\  \hline
\end{tabular}
\end{center}
\end{table}

\newpage

All the usual features of \LaTeX are possible, such as merging cells, wrapping / aligning text etc ...

\begin{table}[!h]

\label{table:sinuous_design_roles}
\def\arraystretch{1.5}
\begin{tabular}{ | c | l | l | p{4cm} |}

\end{tabular}

\end{table}

Finally, a large table, represented in landscape mode is shown in the next page.

\chapter{Equations and code}
\label{chap:equationsandcode}

The \texttt{equation} environment is the answer to all your complex greek formatting requirements. 
\begin{equation}
\label{eq:sinuous}
\phi = (-1)^p\alpha_p\sin{\left[\frac{180^\circ\log{\left(r/R_p\right)}}{\log{\tau_p}}\right]}, \quad R_{p+1} \le r \le R_{p}
\end{equation}

I prefer to use the simple \texttt{verbatim} environment for capturing my code segments.

\begin{Verbatim}[frame=single]
r_total = zeros(0,0);
phi_total = zeros(0,0);
for p=1:length(R)-1
    r = linspace(R(p),R(p+1)+eps,10000);
    phi = ((-1)^p) * alpha *(sin(pi*log(r/R(p))/log(tau)));
    r_total = horzcat(r_total,r);
    phi_total = horzcat(phi_total,phi);
end
\end{Verbatim}
