I'm using quiver() to show flow magnitude and direction, but the arrow heads are tiny, as you can see in the figures. The arrows are scaled by AutoScaleFactor=0.1, to prevent the lines from overlapping. Changing MaxHeadSize doesn't do anything!

I've read ALL the previous questions on changing the arrowhead size and style, and even downloaded some functions from MatlabCentral. But nothing seems to work. I guess the data structure of the quiver plot was changed in one of the recent Matlab versions. Specifically (taken from: In Matlab how do I change the arrow head style in quiver plot?), 

hq1 = quiver(x,y,u,v);
hkid = get(hq1,'children');

results in hkid=empty.

When I tried to use annotation() I ended up with arrows of odd shape and location.

Any help will be appreciated (including referral to an R package), thanks in advance.

    Have you actually tried [this](http://stackoverflow.com/a/18776335/2586922)? (Keep a copy of original file!) – Luis Mendo Jan 10 '16 at 21:56

There is an up-to-date version of the quiver-to-annotation code that control for the arrow size and head width/size separately here:

Here is the figure
