Arrow in 2-D:

r_from_origin = l*[cos(theta),sin(theta)];

Arrow in 3-D:

r_from_origin = l*[cos(phi)*sin(theta),sin(phi)*sin(theta),cos(theta)];

How about annotation()?

annotation(lineType,x,y) creates a line or arrow annotation extending between two points in the current figure. Specify lineType as 'line', 'arrow', 'doublearrow', or 'textarrow'. Specify x and y as two-element vectors of the form [x_begin x_end] and [y_begin y_end], respectively.

or the quiver() function?
