Can I put two mocks of same class in an array?

I am using the mock testing framework to create mocks.

I create two different mock instances of the same class, for example, `obj1 = testCase.createMock(?Foo)` and `obj2 = testCase.createMock(?Foo)`. (The two instances play two different roles in my test.) When I attempt to put these instances in an array, `[obj1 obj2`, Matlab reports any '...error converting from `FooMock_1`to `FooMock`'.

How do I create two different mock instances of the same mocked type?
