MATLAB: How to initialize an object array as a class property

initializationobject arrayoop

Here are two code snippets illustrating my problem:
classdef SomeClass
    properties
        foo;
        bar;
    end
end
and in another file:
classdef SomeOtherClass
    properties
        %Array of SomeClass objects.
        someClassArray;
    end
      methods
          function obj = SomeOtherClass(n)
              %Initialize the array, as n can be large.
              obj.someClassArray(n,1) = SomeClass();
          end
      end
  end
When initializing an object of the second class, Matlab assusmes the someClassArray property is a double, and gives an error:
The following error occurred converting from SomeClass to double:
Conversion to double from SomeClass is not possible.
Error in SomeOtherClass (line 10)
          obj.someClassArray(n,1) = SomeClass();
How do I get around this?

      methods
         function obj = SomeOtherClass(n)
               tmp(n,1)=someClass;
              obj.someClassArray=tmp;
          end
      end
