It depends on what the data are (for example, datetime arrays).
Given the problem described —
Months = repmat(ones(3,1) * (1:12), 1, 5);
Data = [Months(:) (1:numel(Months)).']
Data = 180×2
1 1 1 2 1 3 2 4 2 5 2 6 3 7 3 8 3 9 4 10
% Check1 = Data(24:36,:)
Result = Data(6 <= Data(:,1) & Data(:,1) <= 8, :)
Result = 45×2
6 16 6 17 6 18 7 19 7 20 7 21 8 22 8 23 8 24 6 52
Check2 = Result(28:36,:)
Check2 = 9×2
6 124 6 125 6 126 7 127 7 128 7 129 8 130 8 131 8 132
There are other approaches as well. this is likely the simplest.
