Making lines thick (or thicker) in MATLAB plots

The default line size for MATLAB is 0.5pt, which is a bit annoying when integrating graphs into LaTeX. Consider the following graph made by:

x=1:10;
plot(x,'o-');

You can thicken a line by finding the elements of the line property. Let's say that you wanted to make the line width 4pt, you would do the following:

ch = get(gca,'children'); 
ln = ch(strmatch('line',get(ch,'Type')));
set(ln,'Linewidth',4);

As you can see, the line is much thicker. Play around with getting the 'children', as there's a lot of cool stuff that you can do to help you make your graphs prettier. You can basically do everything in 'edit plots' without changing into edit mode. :)
