how to read data in 1*3 struct for one filed directly?

Hi, I have a struct and the data,

 mystruct = struct([]);
 mystruct(1).a = 1;
 mystruct(2).a = 2;
 mystruct(3).a = 3;

how can I read the data of a directly without using a loop, with a loop man can du it like

for i = 1:length(mystruct)
  value_a(i) = mysruct(i).a;
end

than I get

 value_a = [1 2 3];

maybe man can read it directly with a special syntax.

Thanks forward!!
