MATLAB: USING FOR LOOP TO PLOT SEVERAL LINES

assignmentMATLAB

L=[4:2:20];
%X coordintates for reflaction point x3=L/2;
%Y coordinates for reflection point IS -5
%X coordinate for rays coming back to the surface (y=0 line) is L and all y is 0
First there are rays that goes from point (0,0) to evrey point on the line y=-5 with L/2 as x coordinates and then from these points rays goes back to the line y=0 with L as x coordinate
 I did this
X=[0  2  0   3   0  4  0   5   0  6  0   7   0  8  0   9  0  10;2  4  3   6   4  8   5  10  6  12  7   14  8   16  8  18  10  20];
Y=[0 -5 0 -5 0 -5 0 -5 0 -5 0 -5 0 -5 0 -5 0 -5 ;-5  0  -5   0  -5  0  -5  0 -5  0  -5   0 -5  0 -5  0  -5  0] ;
plot(X,Y)

I have plotetd this using matrix but I am required to plot it using for loop command which I cant here !! could anyone thankfully help me out?

Best Answer

something like this?
 plot(X(:),Y(:))
