How i make a quiver plot between each dot in the same line dot P1(1,:) with P2(1,:); P1(2,:) with P2(2,:) and on....
P1=[121.578100000000 6.97130000000000
115.047800000000 6.22980000000000

D=P2-P1
figure
for k=1:length(P1);
hold on;
quiver(P1(k,2), P1(k,1), D(k,2),D(k,1),0);
end
plot(P1(:,2), P1(:,1), '.b', 'markersize', 15)
plot(P2(:,2), P2(:,1), '.g', 'markersize', 20)
