Can I plot a point with an arrow towards it?

Can I use plot3 (3D plot) in matlab to plot a random point and to have some text in the corner of the figure with an arrow pointing towards that point? I tried the annotation function, but I don't know how to get the normalized position value of the point (for the x,y funtion input pairs). Thanks.

check

 plot::Arrow3d

Is this the same thing what you mean?

I found a few functions in Matlab fileexchange. May be that will help: http://www.mathworks.com/matlabcentral/fileexchange/7470-plot-2d-3d-vector-with-arrow/content/vectarrow.m
