mArrow3.m - easy-to-use 3D arrow

Draw a 3D arrow. Easily specify size, color and even transparency.

Description

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
