YourData = load('merged.txt');
YourData(YourData(:,2) > 279 & YourData(:,2) < 291, :) = [];
save('Newmerged.txt', 'YourData', '-ascii');
Note that I have interpreted "between" as meaning not equal to 279 or 291 exactly, the open interval (279,291), rather than the closed interval [279, 291]

The above code removes all rows in which the second column is in (279,291), producing an output file which has two columns, with each row being one of the original rows.
If you just wanted to remove items from the second column leaving the first column entirely in place, then you would end up with a second column which was shorter than the first column, and MATLAB cannot store numeric arrays which do not have equal number of values in the columns.
I'm wondering if you are trying to exclude data in that range, or if what you want is only the data in that range?
