get a field value from all elements of a structure

If I have a structure s with a field A(1) and A(2) and A(3), where each of these A fields has a field B, I can type:

s = struct

s.A(1).B = 351;

s.A(2).B = 879;

s.A(3).B = 229;

s.A(4).B = 654;

If I type s.A.B it will show all four values as four separate "ans", but if I type temp = s.A.B it only grabs the first value. How do I get all of these values of B into a double array? I could write a for-loop:

for i = 1 : size(s.A,2)

temp(i) = s.A(i).B;

end

Is there a one-liner?

z = [s.A.B];

Thanks, I knew there must be an easy way.

Good intuition. :)
