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!!
