Phil, you're one of the funniest people I know!

I hate bureaucracy and all it's forms.

In order to process the tenth (and onwards) parameter in a bash script, you need to enclose the argument number in curly braces, e.g.:

echo "Parameter #11 is ${11}"

Not doing this introduces all kinds of weird problems.

Usually, papers produced with LaTeX are not accepted unless all fonts are embedded in the document. Doing this is really easy if you're going the LaTeX -> DVI -> PS -> PDF way. Once compiled, just call the following on the postscript.

ps2pdf14 -dPDFSETTINGS=/prepress filename.ps filename.pdf

This should now contain all fonts embedded. You can check this by calling:

pdffonts filename.pdf

As for embedding fonts in eps figures that are produced using MATLAB, this is a little bit more complex.

As for embedding fonts in eps figures that are produced using MATLAB, this is a little bit more complex. Use this m file. Usage is easy. Just run print_eps filename from within MATLAB. An eps with fonts embedded should be produced within the current directory.

Movies are a very useful tool in order to visualise the evolution of a process with time. It's very easy to make movies with MATLAB. Here, we are going to demonstrate 100 random points moving in time. First we open an aviobj which contains the name of the movie. We can define the frames per second for the movie. Under Linux, compression is not possible. However, you can define the quality and compression method on other platforms. The rest of the script simply defines the points and at each iteration adds a random jitter to each point. Every time plot is called, that frame is added to the aviobj. Once aviobj is closed, the movie is saved. Use your favourite editor to view the movie.

fig = figure;

aviobj = avifile('testmovie.avi');

aviobj.fps = 20;



xcoords = 100.*rand(1,100);

ycoords = 100.*rand(1,100);



for i = 1 : 100

    xcoords = xcoords + (-2 + 4.*rand(1,100));

    ycoords = ycoords + (-2 + 4.*rand(1,100));

    plot(xcoords,ycoords,'b*','markersize',10); hold on;

    axis([0 100 0 100]); hold off;

    F = getframe(fig);aviobj = addframe(aviobj,F);

end



close(fig)

aviobj = close(aviobj);

Since the file was 68 MB, I uploaded it to YouTube. Here it is:
