Get class of matlab struct element

I have a matlab struct that has a sub-element such that when I run

class(foo.bar)

Gives the error:

Error using class
The CLASS function must be called from a class constructor.

When I just run foo.bar, ans gets set several times.

How can I find out which class bar belongs to?

I suppose you have a structure array as foo. Example:

>> foo = struct('a',{1 2})
foo = 
1x2 struct array with fields:
    a

>> foo.a
ans =
     1
ans =
     2

>> class(foo.a)
Error using class
The CLASS function must be called from a class constructor. 

>> class(foo(1).a)
ans =
double

Note that foo.a returns here what is called a comma-separated list.
