19790914
19791219
19800310
19800622

Convert the dates to datenum and use logical indexing i.e. use inequalitties.

idx = find(19800310 <= column & column <= 19901214);
At this point you can select corresponding values by
selected_data = YourData(idx,:);
and you can reject corresponding values by
other_data = YourData; other_data(idx,:) = [];
If you are selecting and you want to add an entry before 19800310 then
selected_plus = [Additional_data; selected_data];
If you are rejecting and you want to add an entry where 19800310 would have been then
other_plus = [other_data(1:idx(1)-1, :); Additional_Data; other_data(idx(1):end,:)];
