After updating Matlab to 2014b, arrow.m is not working. It is stopping in line 423 with the error:
Undefined function 'mtimes' for input arguments of type 'matlab.graphics.axis.Axes'.
Error in arrow (line 423) ax = o * gca;
Does anybody have idea?

Graphics handles have changed significantly in R2014b. The author will have to update arrow.m for R2014b and subsequent releases.

It has a new home in R2014b. See: Annotation Arrow Properties.

It looks like it is treating a graphics handle as a double precision number.
It looks like they are pre-allocating a variable by multiplying a handle by 0. When handles were double precision numbers that worked.
Replace that line with
ax = 0;
