If you have exactly 24 data points for each day (one for every hour) then you could use this approach, assume you have your data in an a two dimensional array named data
% determine total number of days of data
numDays = length(data)/24;
% reshape your temperature data so that you have a column for each day, with a row for each hour in the day
Tdata = reshape(data,24,numDays)
% calculate your min and max for each day
dailyMin = min(Tdata);
dailyMax = max(Tdata);
If your data is somehow less regular and you are missing entries for certain hours then you will have to do something more involved

you could also use accumarray for this purpose https://www.mathworks.com/help/matlab/ref/accumarray.html
