### drawing vectors...

• Follow

```Hi,

I need to draw a vector 5eg velocity) centered on a point. The
general structure is the following:

vel=[vx1 vy1; vx2 vy2; ...]
center = [X1 Y1; X2 Y2; ...]

where vx1 and vy1 are velocities on x and y at time step 1 and so on,
and X1 Y1 represent the position on which the vector is applied at
time step 1 and so on...

How can I write a routine? (mainly I don't know the commands for
drawing the vector)

And if I have more than 1 vector/center to draw at each time step?

Thanks
```
