Hello, I have a matrix such as [1 2 3; 4 5 6; 1 3 5; 2 6 9], how to plot 3D trajectories from point [1 2 3] to [4 5 6] then from [4 5 6] to [1 3 5], then from[1 3 5] to [2 6 9] etal? namely, the neighbour points are connected with an arrow line. Thank you

P = [1 2 3; 4 5 6; 1 3 5; 2 6 9] ;
[nx,ny] = size(P) ;
figure
hold on
for i = 1:nx-1
v=[P(i,:);P(i+1,:)];
plot3(v(:,1),v(:,2),v(:,3),'r')
end

Rick commented:Thank you, KSSV, it is very close to the answer I want. Is it possible add the arrow at the end of each line fragment?
Best,
