How to increase the length of the legend line?

Hello, I would like to increase the length (not linewidth) of the line inside the legend. Does anyone has an idea? Thanks you.

 t = [0:0.1:2*pi]
a = sin(t);
b = cos(t);
plot(t,a,t,b,'linewidth',3)
l = legend({'Sinus','Cosinus'},...
     'location','southwest','FontName','TimesNewRoman','FontSize',20);

I don't think it is customizable directly, go to the following links to user-defined function-

The simplest way to do it is to use: -

leg = legend('Plot1','Plot2',...);
leg.ItemTokenSize = [x1,x2];

By default x1=30 and x2=18 so put larger or smaller numbers as x1,x2 to increase or decrease the legend line size.
