This function draws a 3D arrow using a cylinder and cone patch. This allows the use of all patch properties including transparency. It can be used with default parameters (example 1) or user-defined parameters (example 2).

example 1:
> mArrow3([0 0 0],[1 1 1]);
    % draws a black arrow from point [0 0 0] to point [1 1 1]

example 2:
> h = mArrow3([0 0 0],[1 1 1], 'facealpha', 0.5, 'color', 'red', 'stemWidth', 0.02);
     % draws a semitransparent red arrow with a stem width of 0.02 units from point [0 0 0] to point [1 1 1]; h is the handle to the patch object

Works great —at least for simple stuff. Haven't tried doing anything fancy with it.

Sounds good, but not working on R2011b (7.13.0.564). No arrow, no error message.

Very good!
