How can I draw a vertical line upon the horizontal lines in matlab?

I want to draw a vertical line in Matlab upon the concurrent horizontal lines and show the coordinates where the vertical line intersects the horizontal lines.I give a figure here, I want to write a code so that it draws a line first and show the co-ordinates on the intersection point automatically.

It can be drawn, how you have the data? Do you have the data for horizontal and vertical lines shown on the image?

bro i dont know. but after hough transform i get some horizontal lines. now i want to apply a algorithm so that a vertical line flows from left to right and mark the intersection point when it intersects with the image horizontal lines.It also great for me if it shows the co-ordinates on the intersection point.

I gave you code on how to show intersection points in stackoverflow already. :)

L1 =  [0.7290    0.2163
    0.2026    0.9763] ; % line 1 coordinates 
L2 =   [0.5932    0.9677
    0.3044    0.8960] ;  % line 2 coordinates 

figure(1)
hold on
plot(L1(1,:),L1(2,:),'r')
plot(L2(1,:),L2(2,:),'b')
%%Get intersection
P = InterX(L1,L2) ;
%
plot(P(1),P(2),'*r')
%%Show points
text(P(1),P(2),num2str(P)) ;
