Variables in LaTeX

Hello,

To use variables:

% Set the new variable called "\MyVariable" with the value 0.5
\newcommand{\MyVariable}{0.5}

% To use the variable.
\MyVariable

e.g. includegraphics[width=\MyVariable\columnwidth]{img/img.pdf}

Ubuntu LibreOffice Calc graphs to LateX

Here is how it is done!

1. The first thing to do is to get the graph's size
• selce your graph, right click on it and choose "Position and Size"
• Get a printscreen or memorize the size values
2. Copy the graph and open LibreOffice Draw and paste the graph there.
3. Go to Format->Page and change the Width and Height using the above graph sizes
4. Move the graph so that it fits perfectly on to the page.
5. Finally, go to File->Export as PDF
• Better to choose lossless compression
6. Now you can use this pdf file in your .tex document

If you want to use grayscale pdf in your latex document there are some ways to convert the pdf into grayscale.

I use http://greyscalepdf.com/ (or http://online.puzzleflow.com/process/all2gray) to get the job done easily.

cheers!

MATLAB figures in LaTeX

Hey,

Here is how it is done.

1. Open you figure file in MATLAB
2. Goto File->Export Setup...->
3. Apply you modifications like converting to grayscale etc. (Rendering->Colorspace)
4. Choose "Export"
5. In "Save as type" choose EPS
6. Now you can use this EPS file in you .tex file:

\begin{figure}[t]

\begin{center}

\includegraphics[width=\columnwidth]{figure.eps}

\caption{my caption}

\label{fig:system}

\end{center}

\end{figure}

and choose latex->ps->pdf in your project builder (e.g. in TeXnicCenter)

Or if you want to convert this to pdf use the epstopdf utility that comes with MikTeX in the command prompt:

epstopdf figure.eps

and use it like this:

\begin{figure}[t]

\centering

\includegraphics[width=columnwidth]{figure.pdf}

\caption{my caption}

\label{fig:system}

\end{center}

\end{figure}


Note:
For some reason, direct export to pdf does not preserve the figure size.
