Object array method dispatching

In MATLAB's new object model (classdef, etc): If I have an array of the object, and I call an ordinary method, is the methods called for each object, or for the entire array, i.e. is a single object passed into the method, or the entire array? I know that in the old model, it got dispatched as the entire array.

If you have:

classdef MyObject

methods
    function foo(obj)
    ...
end

And you then call

>> foo(myObjArray)

Then the single call to foo() will receive the entire array. From there you can write code to handle a scalar case of obj or vector case of obj.

It depends on if your method is vectorized. For a trivial example:

Not vectorized

function result = mySimpleMultiply(a,b)

result = a*b;

Vectorized

function result = myVectorizedMultiply(a,b)

result = a.*b;
