Hello,
I have the following question:
How do I place a cone along a line or two points?
I know how to generate a cone:
cylinder([1 0])
But how do I move it where I want it to be?
Thank you!

% get the coordinate x, y and z
[x,y,z]=cylinder([0 1])
% New coordinate
x=x+2
y=y+10
z=z+5
%----new cone----------
mesh(x,y,z)

I would like to create an arrow by giving two points and a color.

If you want to plot cone-shaped arrowheads in 3D, use the coneplot function.

Unfortunately, no. The coneplot function is set up for volume data, so if you only want a quiver3 plot with cone-shaped arrowheads, I would settle for the regular quiver3 plot instead. I have no experience with converting quiver3 plot data to volume data to use with coneplot, and it has defeated my attempts to do so just now.

Is there maybe a way to rotate a cylinder so that it will be aligned along two points?
