I have hourly temperature data (without date and time) about 5200. I want to extract daily mean and store the output as a vector using a for loop. Can anyone give me useful suggestion?

One approach:

T = 1:5200;                                     % Temperature Vector
for k = 1:24:numel(T)
    k2 = ceil(k/24);
    idx = k:(min(k+23,numel(T)));
    DailyMean(k2) = mean(T(idx));
end

There may be more efficient ways to do this, depending on what your temperature data actuallly are.
