Arrow plotter

very simple customizable inline function to draw arrows.

Very simple customizable inline function to draw arrows. Lightweight and fast for drawing many, many arrows. You customize fill color, linewidth, etc... Tune theta up if you want a wider arrowhead.

takes two [x y] coords and one double, headsize, that allows you to tune the length of the arrowhead to your liking. It's normally set to (length of the line) / 2.5, the headsize variable acts as a multiplier of that (in the numerator).

made this in just a few minutes because the other arrow.m thing is too unwieldy and slow. Enjoy!
