How to plot a 3D vector as an array: attempts and problems

$

I am using MC v.11.2, and I attempted to plot a column vector  (3x1), as one would do in Vector algebra.

 

I saw in the forum for help, and I found the following method:

 

1. Take the vector and turn it in the first row of a matrix of dimension 2x3

2. Place in the second row  of the matrix the coordinates of the origin of the vector (in my case  zero)

3. Create a 3D Scatter (or Field) Plot and write the three columns of the above matrix.

 

I tried in MC 15, and it works for more than one vector. I re-tried several times the same with v.11.2 and the following error is shown (see figure).

I timidly ask:

a) Is it possible to plot more than one vector in MC v.11.2 with the above method?

b) If it is possibile with the method above, where is my error and how many vectors can one plot (I would need at least 3 or 4).

c) If it is impossible, are there some other effective methods able to do it with MC v11.2?

 

Thanks for any feedback.

BTW,  this is one field where MC lies behind as compare to competitors, where there is a specific command to plot vectors without any additional trouble.
