Answer 1

Amongst other solutions, here is one using annotation where you can set the arrow properties including (x,y,width,height) within the current axes, the head and line properties.

h=annotation('arrow');
set(h,'parent', gca, ...
    'position', [50 5 20 2], ...
    'HeadLength', 1000, 'HeadWidth', 100, 'HeadStyle', 'hypocycloid', ...
    'Color', [0.4 0.1 0.8], 'LineWidth', 3);
