Aren't these two lines of code?
aspect_ratio = results(index).MajorAxisLength /results(index).MinorAxisLength;
arr(k,1) = aspect_ratio;

Use the debugger to examine the problem: How to use the debugger
Set a breakpoint in the failing line - after fixing the problem that these are two lines (see my comment above). Or let Matlab stop automatically when the error occurs by typing this in the command window:
dbstop if error
Now run the code again. When Matlab stops, check the locally used variables:
class(results)
size(results)
class(index)
size(index)
I guess, that index is empty. Then results(index).MajorAxisLength has no element, such that you do not have an input for the division.
