Calling an object method on multiple objects of the same class

Is there a nice shortcut for calling an object method (i.e. without using a for loop) on multiple instances of a class at the same time which are collected in a vector?

What I do now:

A = [SomeObject, SomeObject, SomeObject]
for n=1:numel(A)
  A(n) = A(n).callSomeMethod();
end

I tried

A = [A.callSomeMethod()];

and

A(:) = A(:).callSomeMethod();

but this gives an error.
