Why does arrow fail? (R2015a)

A simple call to arrow fails on 2015a with:
Undefined operator '*' for input arguments of type 'matlab.graphics.axis.Axes'.
Error in arrow (line 423)
ax = o * gca;
Where on line 412: o = ones(narrows,1);

If arrow is a FEX submission, note that HG2 ‘broke’ many FEX files that used the more flexible HG1 functionality. If they are not updated to be compatible with HG2 (and I suspect many cannot be), you have to use them with R2014a or earlier.

I'm not sure what "arrow" is, but that code fragment looks like it's trying to create a vector which holds "narrows" copies of the handle of the current axes. A much more reliable way of doing that would be something like:
ax = repmat(gca,[narrows 1])
