Matlab: changing font size on xlabel and ylabel

问题

I am doing the following (this is a simple example to illustrate the problem):

a = [1,3,4];
b = [1,4,5];
plot(a,b,'LineWidth',4);
xlabel('recall','FontSize',35);
ylabel('precision','FontSize',4);

and it produces:

As you can see the 'FontSize' is having no effect. I have also got the properties of the xlabel shown below:

xl = xlabel('recall','FontSize',35);
get(xl)
    FontAngle = normal
    FontName = Helvetica
    FontSize = [35]
    FontUnits = points
    FontWeight = normal

You have to install packages:

• xfonts-100dpi
• xfonts-75dpi.

as suggested in this thread because Ubuntu 12.04 doesn't come with MATLAB specific fonts.
