Plotting Multiple Lines from two end points in a matrix without a loop?

I have sets of two end points in xyz coord in a matrix in the form of

V (2,3,418)

so for example V(1,:,1) would call the start point of the first line as [x, y, z ]

and V(2,:,1) would call the end point as [x,y,z]

I can plot this in a loop like

for i = 1:length

plot3(V(:,1,i),V(:,2,i),V(:,3,i))

end

I was wondering if theres a way I can plot this all at once with out a loop?

one way (which is kind of bad practice) is to make each point separated by a NaN, which interupts the line. This way is still probably better because it doesn't create 418 line objects

example:

Length=418;
V2 = zeros(3*Length, 3);
for i = 1:Length
    V2(i*3-2:i*3, :) = [ V(:,:,i); NaN(1,3)];
end
plot3(V2(:,1), V2(:,2), V2(:,3))

this does also end up making every line the same color, in case one of your goals was to keep them different.

The other method would be to switch the third dimension with the second dimension, which took me a while to figure out.

V2 = permute(V, [1,3,2]);
plot3(V2(:,:,1), V2(:,:,2), V3(:,:,3))

the plot or plot3 command will separate each column into its own line if you pass in matrix arguments. getting that to be intuitive is really hard.

Thank You! That is very useful

so I left the tab open for this, and I got thinking again would a quiver3 be more what you're looking for?
