How can I enlarge the legend box-size?

Hi,
I am plotting two curves and defining their parameters using the legend. The code is as follows
hleg1 = legend ( ['$ n/n_c = $' num2str(den1)], ['$ n/n_c = $' num2str(den2)] );
set(hleg1,'Interpreter','latex')
set(gca,'fontsize',15)
My problem is that as soon as I change the font size to 15 the box around the legends doesn't expand automatically and I have legends of the curves going outside the legend box. Can anybody suggest something?

legend() is implemented by creating a new axis, the handle of which is returned. You should be setting Interpreter and fontsize for the text entries rather than the axis.
[hleg1, hobj1] = legend( ...);
textobj = findobj(hobj1, 'type', 'text');
set(textobj, 'Interpreter', 'latex', 'fontsize', 15);
Then if you find you need to, set() the Position property of hleg1.

You have a legend with two entries. The second value returned by legend() is the handles to the objects that went up to make the legend, including the text objects. The findobj() reduces the list down to just the text objects. The set() then affects all of those text objects. So already this code works for legends with multiple entries.

set(hleg1,'position',[0 0 0.2 0.2])
In general
set(hleg1,'position',[x0 y0 width height])

A simple workaround is to put additional spacing after the text.
E.g., by using \quad:
hleg1 = legend ( ['$ n/n_c = $' num2str(den1) '$\quad$'], ['$ n/n_c = $' num2str(den2) '$\quad$'] );
