I wanted to make a vector plot with a discretized data set that has 6 columns (x, y, z, vx, vy, vz). The first three columns specifies the starting point of the vector, (vx, vy, vz) specifies the x, y and z components of the vector. I think I should probably use "quiver3" to make the plot as the example ( https://www.mathworks.com/help/matlab/ref/quiver3.html ) here is what I need. However, I cannot find how the data set "wind" is formatted. My data looks like the following, can anyone help me with this? Thanks in advance.
My data set:
%x y z vx vy vz
Data = [
0.250 0.250 0.125 0.000 4.000 0.000
0.250 0.750 0.125 4.000 0.000 0.000
0.750 0.250 0.125 -4.000 0.000 0.000
0.750 0.750 0.125 0.000 -4.000 0.000

0.500 0.000 0.500 -4.000 4.000 0.000
0.000 0.500 0.250 0.010 -0.010 0.000

0.500 0.500 0.500 -0.010 0.010 0.000 ];
