plotting 3D vector field in MATLAB in many different ways

Recently I read post from Dr. Doug Hull's blog:

http://blogs.mathworks.com/videos/2009/10/23/basics-volume-visualization-19-defining-scalar-and-vector-fields/

I liked this video tutorial so much and I really felt that should finish the 'homework' assigned at the very end. So I spent sometime on it and here are my code and figures.
