Multipline plotting

Hello,

I need to plot over 3000 line segments on a figure, normally I use a loop

close all A=[1 2 3 4;2 8 9 10;5 6 7 1; 8 5 2 1]% example matrix

figure

hold on

for counter=1:size(A,1) X= [A(counter,1) A(counter,3)]; Y= [A(counter,2) A(counter,4)]; line(X,Y) end

but since I have the coordinates in one matrix it seems not efficient to use loop for the plotting. Is there another way of is this just the way to go? I already consulted this thread: http://www.mathworks.com/matlabcentral/newsreader/view_thread/240110 , so I thought using a loop is inevitable

thanks for any input

X = [ A(:,1) A(:,3) ]';
Y = [ A(:,2) A(:,4) ]';
line(X,Y,'color','b')

ok, this was stupid of me, tried that solution but forgot to transpose, sorry, THANKS
