Matlab：如何合并结构数组字段的值

Question

Is it possible to easily combine values from struct array fields into a single array without looping through each individual struct in the array?

For reference, see the attached code:

% build random struct array with only one field
% for demonstration only
clear i s out;
for i = 1:10
    s(i).value = rand;
end
s

% not working, as it returns multiple results
s(1:end).value

% combine all "value" into a single array using for-loop
out = zeros(length(s), 1);
for i = 1:length(s)
    out(i) = s(i).value;
end
out

Simply put, the goal is to kind of "merge" all "value" fields.

Answer 1

You can get it using the following:

out = [s.value]

The s.value returns all the values and [...] to make an array of them.
