Draws two dimensional vectors on Matlab figures. Uses complex numbers. Example provided. Should be used in conjunction with 'export_fig' for high quality output. For each vector, start point, end point, arrow head length, arrow tip angle, colour, & line width are specified. If pol2rec(magnitude, angle) also downloaded, can take vector start/end point in polar form.
How it works: arrow head is 250 carefully placed lines at right angle to vector, finishing at end point of vector.

Version Published Release Notes

Previous version drew arrow for vector as horizontal or vertical lines. Now, arrow consists of series of lines at right angles to the vector. Additional argument required, angle of arrow (deg). Error handling arrow length > vector length
Changed description to indicate code fixed; there is no longer a problem with some arrows not looking right.

Added screenshot with output using export_fig. Other function here, pol2rec() is good to use in conjunction with this. In this way, polar form (magnitude and phase) of vector can be entered.
