You could, for example, create a cell array:
C = {};
C{1,1} = s(1).f1;
C{1,2} = s(1).f2;
C{2,1} = s(2).f1;
C{2,2} = s(2).f2;
I suggest making a for-loop, but I hope you get the idea.
BTW there's also a build-in function struct2cell which does this for you ( except it creates a multidimensional array ).

You'd do this:
st = load('mat_str.mat')
f1 = vertcat(st.s.f1)
f2 = cat(3, st.s.f2)
