Adjust size of title and axis labels in figure/eps

[poster]

I have a Matlab figure, like:

x=0:0.01:4;

y=sin(x.*x);

plot(x,y);

title('Some title');xlabel('some x-label');ylabel('some y-label');

I save this figure with saveas(gcf,'myfig','epsc') or manually by using the GUI as a eps vector grapfic. Now I'd like to include it in a Latex file by using \includegraphics. But the problem I have, is that the title and labels are way too small to be read. So how can the size of these labels be increased?

textwidth and scale in Latex are not what I mean. They are no solution to this.

Thanks!
