The main constraint here is the parfor "sliced output" requirement. Basically you cannot directly update a single struct using parfor, but you can use parfor to assemble the fields separately, and then put them together into a struct afterwards. For example:
parfor i = 1:7
name{i} = sprintf('name %d', i);
value(i) = randi(10);
end
result = struct('name', {name}, 'value', {value})
