How can I determine if elements in an array are equal to a scalar

I have an array like the following

 a = {[1] [3] ['A'];[3] [1,2] []};

and I want to check to see if each element of the array is equal to 3 or something, so I would want an output like this:

   Output = [0,1,0;1,0,0];

This seems like something that should be easy to do but I can't figure it out. I tried doing

Output = cellfun(@eq,a,3)

But that doesn't seem to work.

Output = cellfun(@(x)isequal(x,3),a);
