You can create a struct of structs and use loops to access the inner structs' fields. Here is an example using the code sample that you have provided:
num = [3, 4, 8];
num_weeks = length(num);
Week = struct(); % Initialize the outermost structure
for n = 1:num_weeks
% Create the nested structures for each week
People = struct('FirstName', {}, 'LastName', {}, 'PhoneNumber', {});
% Add the specified number of People structures to the current week
for i = 1:num(n)
People(i).FirstName = '';
People(i).LastName = '';
People(i).PhoneNumber = '';
end
% Add the nested People structure to the current week in the outermost structure
Week(n).People = People;
end
This can get you the desired result. Hope it helps!
