How to draw bunch of line segments?

I would like to draw [x1 x2],[y1 y2] line segments, and I have data in the form X1(i) = x1 etc. and i=1:1000; Is it possible to draw the lines without a for cycle?

You can. But what is the wanted result?

X1 = rand(1, 10);
X2 = rand(1, 10);
Y1 = rand(1, 10);
Y2 = rand(1, 10);

subplot(1,2,1)
plot([X1; X2], [Y1; Y2])      % A bunch of separate lines

subplot(1,2,2)
plot([X1; X2].', [Y1; Y2].')  % Two polygones

x=1:10;
y=rand(size(x));
line(x,y);
