the arrow.m does not work any more in matlab 2014b version.

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?

Where did arrow.m come from?

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

Answer 1

[Star Strider]

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

Answer 2

[Doug Hull]

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;
