MATLAB OOP: How does the end function get called when passed to a class method

I have a class in MATLAB that uses a class method for specialized indexing into the class data. I am interested in overloading the end(obj, k, n) method so that it is easy to write indexing expressions into this method, but I have already overloaded this function for use in subsref(obj, s).

Could someone please explain to me how MATLAB calls the end method in the following:

>> obj = myClass; obj.myIndexMethod(1:end)

end is implemented as a function ind = end(obj, k, n). k is the index of the expression containing end, and n is the total number of indices in the expression.

So, for example, when you call a(1,end,1), k is 2, as the end is in argument 2, and n is 3 as there are 3 arguments.

ind is returned as the index that can replace end in the expression.
