for i=1988:2020;

months_i=dates_i.Month;

end

I want the months_i to be read as months_1988, then months_1989, etc because I'm looking at arrays from those ~20 years and am digging into each array with multiple loops underneath. Thank you!

You can do it with eval but it’s not recommended. Use a cell array instead or another struct

month{i} =['month_',num2str(i)];

end
