Change quiver arrow size and width in 2014

In quiver.m in 2014, there are parameters for controlling the quiver arrow size and width as:

alpha = 0.33; % Size of arrow head relative to the length of the vector

beta = 0.3; % Width of the base of the arrow head relative to the length

however changing them does not make a difference. How to change quiver arrow size and width in 2014? Thanks.

In 2013, there is a way to change the alpha and beta by changing the file refresh.m located in folder \toolbox\matlab\specgraph\@specgraph\@quivergroup\@quivergroup. I'm looking for a way to achieve the same in 2014. Thanks.

I don't know exactly what you want, but perhaps try changing the AutoScaleFactor or the MaxHeadSize LineWidth etc. properties of the quiver object.

q = quiver(rand(10,1),rand(10,1),rand(10,1),rand(10,1))
q = 
Quiver with properties:
