This code allows you to create simple, yet powerful three dimensional arrow. As it is derived from the surf command, it may be memory intensive, but well worth the cost for crisp visualization of data using phong shading and MATLAB's lighting options.

Example:
arrow3D([0,0,0], [0,0,1],'red',0.82);

%% Creates a single arrow starting at the origin with magnitude=1 along the z-axis, in red, with an arrowhead 18% of the length and the stem 82% of the length.
