Plotting Matlab Figures and linking them to Latex

I am writing my thesis which means I need to do lots of latex! I am plotting figures in matlab but it is bit tricky linking matlab figures to latex!

So, here's the perfect way to get things done!

1. Plot all the data
2. Call tightfig script to remove margins (
http://www.mathworks.com/matlabcentral/fileexchange/34055)
3. Save the file in pdf
4. Plot in latex!

Example Latex:
\begin{figure}[!ht]

 \centering

 \includegraphics[scale=0.45]{Figures/Chap2/Fault_Profile.pdf}

 \caption{Different Fault Resistances.}

 \label{fig:fault_profile}

\end{figure}

Example Matlab Script:
