arrowz(startpair,en​dpair,varargin)

Draw an easily adjustable arrow

ARROWZ draws an easily adjustable arrow from startpair to endpair. These
pairs should be vectors of length 2. The input of ARROWZ can vary from 2
to 6 inputs.
This arrow can be specified by a startpair, an endpair, also the thickness and color of the shaft and the arrowhead can be customized.

ARROWZ(starpair,endpair) creates an easy arrow, a line plot from
startpair to endpair, with an additional head within the direction of the
endpair. Input format is [x y],[x y].
ARROWZ(starpair,endpair,headsize) is able to adjust the size of the head.
Default size is 1.
ARROWZ(starpair,endpair,headsize,shaftsize) sets the thickness of the
shaft to the desired size. Default size is 1.

ARROWZ(starpair,endpair,headsize,shaftsize,color) specifies the color of
the total arrow. These values should be provided as RGB. Default is black
[0 0 0].

ARROWZ(starpair,endpair,headsize,shaftsize,headcolor,shaftcolor) colors
the shaft of the arrow into a seperate color. Default is black [0 0 0].
