Hai,
I have drawn two intersecting lines. The point of intersection of these two lines is a dot. I need to increase this dot size, of the intersection. How could I do this?

You can always plot a symbol at the point of intersection
x = -10:10;
y = x;
y1 = -x;
plot(x,y,x,y1,'b');
hold on;
h = plot(0,0,'ko','MarkerfaceColor',[0 0 0]);
If you really want to make the size bigger than the default, use the MarkerSize property.
